A.
Transportation Plans and Policies
The purpose of this section is to summarize policies and plans in the Urban Ring Project Corridor in
order to: 1) coordinate transportation efforts and land use; 2) avoid conflicts with, potential adverse
impacts, and unintended consequences of other projects and policies; 3) leverage off projects
undertakings; 4) improve sharing of information across institutional and bureaucratic barriers; and 5)
refine and design the second phase of the project to meet community needs.
Local, institutional, regional, state and federal policies with importance to the Urban Ring are
discussed below. This section also discusses projects along the Urban Ring Project Corridor that are
in the planning, design or construction phase. Projects that may be in conflict with the Urban Ring
Project Corridor are also identified.
Plan and Policy Approach
The wide range of government jurisdictions involved in the corridor made it necessary to organize
policy-related information into categories. The locally-oriented planning priorities that have marked
the Urban Ring planning process make it logical to present policy descriptions in similar order as
follows:
•
Local Plans and Policies;
Page 1

•
Institutional Plans;
•
Regional Plans and Policies;
•
State Plans and Policies; and
•
Federal Plans and Policies.
This discussion focuses on those agencies and jurisdictions likely to have a direct role in the planning
and/or implementation of Urban Ring transportation improvements, though other entities not
discussed herein would also have some role. In order to gather requisite background information and
documents, the Urban Ring Phase 2 consultant team has conducted internet research and
coordinated with a range of agencies, including corridor municipalities; institutions and institutional
groups; the Boston Region MPO and the Boston regional planning agency, the Metropolitan Area
Planning Council (MAPC); state agencies and authorities; and federal agencies. The various
documents and information sources were reviewed for policy statements, key information, and
consistency with Urban Ring Phase 2 proposals, and then summarized.
Local Plans and Policies
The chief executives of six municipalities of the Urban Ring corridor (Boston, Brookline, Cambridge,
Chelsea, Everett and Somerville) jointly put forth the policy that the economic vitality of their
jurisdictions requires them to coordinate their land use planning with implementation of the Urban
Ring project. These six municipalities formed the Urban Ring Regional Planning Compact in 1995
and adopted a set of planning principles committing themselves to working with the MBTA during the
Urban Ring project.
At the local level, each of the six local jurisdictions in the Urban Ring Regional Planning Compact
provided information concerning its transportation plans and policies. Although the City of Medford is
not a signatory to the Urban Ring Compact agreement, Medford is included in the project corridor, so
policy information on Medford was also obtained, focusing on the Wellington Station area. The plans
and policies for each local jurisdiction relating to the Urban Ring project are discussed below and
summarized in Table A-1.

TECHNICAL TRAFFIC REPORT
Boston
Boston's transportation policies are directly related to its development policy, which focuses on ensuring that
future economic growth is balanced with the protection of neighborhoods and the environment. Within and
adjacent to the Urban Ring corridor, the City of Boston has undertaken numerous district planning efforts
(including the LMA, Dorchester, Fenway, the Southwest corridor area, and Roxbury) that relate directly to the
proposed BRT routes and are supportive of transportation improvements in the corridor.
Boston’s transportation vision is laid out in the Boston Transportation Department’s 2000-2010 Citywide
Transportation Master Plan, Access Boston. The plan addresses the various modes of travel (walking,
automobiles, transit and bicycles) to benefit all users of transportation systems. This initiative is driven by a
"doing while planning" approach with an emphasis on implementation during the process. It focuses on issues
that were identified through public dialogue in a year-long workshop series. The plan, a multi-report effort,
prioritizes programs and projects for the short term and develops strategies for the coming decade. Separate
sections of Access Boston include:1
•
Parking in Boston (December 2001);
•
Boston Bicycle Plan (May 2001);
•
Pedestrian Safety Guidelines for Residential Streets (August 2001);
•
Public Transportation and Regional Connections Plan (March 2003); and
•
Transportation Fact Book and Neighborhood Profiles (May 2002).
The goals and objectives in the various Access Boston components support improved public transportation in
the Urban Ring corridor. In particular, public transit goals in the Access Boston Public Transportation and
Regional Connections Plan include the following:
•
Link the bus system to commuter rail and trolley lines;
•
Create exclusive bus lanes;
•
Create a plan to connect Boston’s residential and commercial areas with a network of transit lines;
•
Work toward creating a more integrated and efficient public transportation system; and
•
Create better suburban connections by public transit.2
In addition, the state’s 2006 Economic Stimulus Bill allocates portions of the state budget to improvements
intended to stimulate economic growth in Massachusetts. The bill covers transportation improvements,
including road, pedestrian, and infrastructure projects, and specifies planning, design, and construction
projects in downtown Boston and in the vicinity of the Urban Ring corridor. Some key projects covered in the
bill include new signals along major arterials; traffic and transit improvements in the LMA, Fenway, and
Kenmore Square areas; and a multimodal commuter rail and bus station and parking facility in North Allston.
The City of Boston and EOT are coordinating on the various projects slated as part of the Economic Stimulus
Bill relative to the Urban Ring project.
Brookline
The Town of Brookline transportation policy is tied into its growth strategy of consolidating and enhancing
existing developed areas. The focus of transportation improvements is on enhancing transportation and

parking options for the entire Brookline community. The town has anticipated significant development on
Route 9 due to major new projects planned in Boston and Newton over the next several years. Brookline has
initiated discussions with state and regional bodies regarding undertaking a sub-regional corridor study for
Route 9 in conjunction with surrounding communities to identify a regional approach to the future of the
corridor. The Brookline Comprehensive Plan 2005-2015 visions an increased transit use by Brookline
3
residents after the full development of the Urban Ring transit service.
Following is a list of some of the specific transportation policies of Brookline.
•
Work with state government and the Cities of Boston and Newton to create a long-term transportation
strategy for the Route 9 corridor that balances local and regional needs;
•
Work with the MBTA to explore potential near- and long-term transit options that serve Brookline;
•
Play an active role in advancing development of the Urban Ring, particularly Phase 3;
•
Promote TDM measures in new development to limit impacts on the roadway network; and
•
Enhance accessibility of all town facilities to the meet the requirement of the Americans with Disabilities
Act (ADA).
The focus of current transportation improvement is on providing more efficient and safe pedestrian and
vehicular operations through the following programs:
•
Beacon Street reconstruction;
•
The Town’s Street rehabilitation program;
•
The Town’s Sidewalk rehabilitation program; and
•
Signal modernization; and traffic management policies, including traffic calming.
Cambridge
The City of Cambridge growth policy seeks to reverse the trend, evident in recent decades, of progressively
greater automobile use. With most employees commuting into Cambridge from other towns, the city seeks to
encourage travel from those other towns by means other than the automobile where possible.
In order to accomplish its growth management goals, the City of Cambridge implemented a Vehicle Trip
Reduction Ordinance in 1992, which set forth provisions for accomplishing its goal of reducing vehicle trips.
Other relevant initiatives are the Cambridge Pedestrian Plan, Cambridge Bicycle Plan, and findings of The
Green Ribbon Report. Additionally, the Cambridge Growth Policy Document outlines 10 transportation policies
to encourage transit and non-automotive travel; reduce automobile and truck through-traffic in neighborhoods;
reduce congestion; reduce reliance on single-occupant vehicles; and promote clean alternative vehicle
technologies.4
In January of 2000, in response to price pressures on the residential markets induced by the city’s booming
computer and biotech industries, and resident perceptions of diminished quality of life from the associated
scale of development and traffic impacts, the City of Cambridge imposed an 18-month city-wide moratorium on
growth and significant down-zoning from industrial to residential uses. During this time, Cambridge underwent
a growth-management strategic planning process with its residents, business leaders, MIT, and a
multidisciplinary team to unlock the potential of the area and preserve the characteristics most cherished by
neighborhood residents. The city produced plan supported by residents, business leaders, and the city, that

cleared the way for more than 12 million square feet of growth, which was the same amount proposed before
the moratorium, but now re-envisioned in a new, mixed-use, pedestrian-friendly, transit-oriented form. The
Eastern Cambridge Planning Study5 strategically addresses the key issues of development density, scale, and
traffic in a way that allows for continued growth of the city’s national high-tech and biotechnology business
center, while preserving and enhancing the adjacent neighborhood’s walkability, park land, and access to the
Charles River Basin – the area’s premier open space system. The plan enables the city to grow while
protecting the neighborhoods’ residential character. It recommends detailed zoning for different districts, a
retail strategy and transportation plan, and specific guidelines for new development areas. Eastern Cambridge
residents and the Cambridge City Council endorsed the study as a way to allow growth and channel its
benefits into the creation of an improved public realm and quality of life for residential neighborhoods.6
Chelsea
The City of Chelsea's transportation policies are related to and supported by its growth policies. The policies
and plans include reducing the volume of commuter traffic that cuts through Chelsea; consolidating and
relocating the off-ramps from Route 1 that currently pass by the high school and residential neighborhoods;
possible relocation of the Chelsea Commuter Rail Station; improving maritime facilities of Chelsea Creek;
improving access to Logan Airport; reconstruction of the Chelsea Street Bridge; and providing better public
transportation to support redevelopment of the waterfront. The city has applied for temporary trail use along a
portion of the CSX Right-of-way (ROW) between Chelsea Creek and Griffin Way. The CSX ROW is in the
abandonment process, and the proposed trail along the CSX ROW is consistent with the proposed BRT
alignment in the area, which would implement a busway in the CSX ROW north or Griffin Way.
Consistent with the state development goals as set forth in Smart Growth policies and programs, the City of
Chelsea has made a priority of developing 1,200 new housing units by 2008. The Anchor Projects Program
aims at reshaping the physical landscape of the entire community by identifying where the greatest amount of
development can take place. The four areas that have been identified include: Chelsea Waterfront, Parkway
Plaza, Everett Avenue Urban Renewal District, and Mystic Mall. The Urban Ring corridor travels through many
of these areas.7
Approximately 65 acres are governed by the Everett Avenue Urban Renewal Plan. As part of the Chelsea
Residential Overlook Project, the city has begun to redevelop 10.5 acres in Phase I and an additional 7.3
acres in Phase II. The plan seeks to convert the largely dilapidated industrial/commercial district into a dense
mixed-use urban development. The Urban Ring Phase 2 alignment overlaps with this plan on Everett Avenue,
Revere Beach Parkway, and the Chelsea commuter rail station.8
Everett
Within the City of Everett, the transportation priorities include adequate public transportation in the Parkway
Industrial Area and the South Everett Industrial Area. The city seeks improved bus service to commercial and
industrial centers of employment, and has proposed a potential commuter rail station.
Recommendations in the city’s Growth Management and Development Study include:
•
Continue to implement the recommendations of the “Operation Industrial Uplift” study pertaining to the
Parkway area;
•
Reconstruction of Vale Street;

•
Explore increasing development parcels adjacent to “paper streets” and used right-of-ways (ROWs)
including East Summer Street, Fourth Street, Fifth Street, and Beech Street; and
•
Relocate, extend, and reconstruct Terminal Street.
These improvements are located within the Urban Ring corridor, and would result in improved roadway
circulation in the vicinity of the project.
Medford
In conjunction with the cities of Malden and Everett, Medford has formed a tri-city partnership (the Tri-city
Mystic Valley Development Commission) to create a regional technology development project called River’s
Edge (formerly “TeleCom City”). This 30-acre mixed-use development would include several area universities,
federal and state government agencies, and private companies. Plans call for over one million square feet of
office/research space, housing and retail. Phase 1 would include up to 200 units of housing and 440,000 sf of
commercial space.9 With over 7,500 potential new jobs, Medford is making an effort to reposition an
abandoned manufacturing-based economy into a new global technology-based economy. Much of the River’s
Edge project site is located within a half mile of the proposed Urban Ring alignment. The mixed use nature of
the River’s Edge project would likely provide a valuable source of ridership for the Urban Ring service. On
December 22, 2005, the new master plan for River’s Edge was approved by the Medford Council. Construction
has begun on the first office building, 200 River’s Edge Drive, and projected to be available for occupancy in
January 2009. Work on apartments will begin soon.10
The City of Medford also issued a master plan for Medford Square in June 2005. Medford Square is located
approximately two miles from the Urban Ring, providing the opportunity for potential bus connections from the
square to the Urban Ring service.
Somerville
The City of Somerville has completed master planning efforts for Union Square (Union Square Transportation
Plan, September, 2002) and Assembly Square (Assembly Square Transportation Plan Final Report, May 13,
2003) areas. A main focus of these efforts is to improve transportation services and facilities as a way of
spurring economic revitalization in these areas. In addition, EOT is evaluating alternatives for improving transit
services to Somerville. EOT is currently pursuing the Green Line Extension project, with proposed extension of
the Green Line from New Lechmere Station through Somerville in two branches: one to Union Square and the
other along the Lowell commuter rail line right-of-way to Medford Hillside near Tufts University. Somerville is
currently working on a Union Square zoning amendment to establish a Planned Urban Development (PUD-C)
zoning overlay district and Union Square Arts overlay district with facilitation by City-Wide Amendments. This
type of mixed use development encourages non-automobile travel modes.
A document entitled the Assembly Square Mixed-Use District, completed in March of 2004, describes
development standard and design guidelines for Assembly Square development. One of the district’s goals
listed in the document is to encourage transit-oriented development.11 Phase 1AA of the Assembly Square
Development includes an IKEA store and the construction of Assembly Square Drive. This project was
conditionally approved at the October 18, 2007 Planning Board Meeting. The IKEA store is anticipated to

break ground in the summer of 2008 and open in the fall of 2009. The next phase of development in Assembly
Square will be Phase 1A, composed of primarily mixed-use retail and residential.12
In summary, the City of Somerville has pursued transportation improvements through:
•
Development of Land Use and Transportation Master Plans for Assembly Square;
•
Proposal for a new Orange Line station at Assembly Square;
•
Renewal of the Assembly Square Commercial Revitalization District Plan;
•
Reduction of air pollution by implementing a Transportation Demand Management (TDM) program for
shuttle service to complement MBTA services;
•
Increased use of High Occupancy Vehicles and transit and reduce Single Occupant Vehicles; and
•
Transformation of the Inner Belt district to office and biotechnology uses.
All of these programs would support Urban Ring planning goals and increase the demand for transit use in the
vicinity of the Urban Ring corridor.
Local Plan and Policy Summary
The seven local jurisdictions have transportation and growth policies that, while exhibiting some variation, are
consistent in their overall objectives and goals. One of the critical issues facing all compact communities is
how to encourage, stimulate, and accommodate development and growth in an environmentally sensitive
manner. Cambridge and Boston are trying to curb the increase in automobile travel while continuing to
encourage development. Everett, Chelsea and Somerville are looking to revitalize areas, especially along the
waterfront, which have traditionally been industrial sites. All communities have embraced public transportation
as a key factor to achieving their goals of growth, revitalization and decreased automobile use, and have
undertaken planning efforts to address and guide future development and revitalization. Community and
citizen involvement have been instrumental in focusing and guiding these planning efforts. Close coordination
with each jurisdiction should allow Phase 2 of the Urban Ring to play a prominent role in each community’s
growth.
The City of Boston has been working with each of its neighborhoods to develop community master plans to
guide future growth and development. The Urban Ring LPA alignment passes through several of these
neighborhoods including Roxbury, Fenway (including Audubon Circle), Longwood Medical and Academic
Area, East Boston, Allston, and South Boston. Other neighborhood communities such as Cottage Farm in
Brookline have been active in the Urban Ring process. The Urban Ring has coordinated with these
neighborhood groups throughout the planning process and will continue to as the project progresses.
Institutional Plans
A large number of community institutions are located within the Urban Ring project corridor. Key medical
institutions include: Beth Israel Deaconess Medical Center; Brigham and Women’s Hospital; Children’s
Hospital Boston; Harvard Medical, Dental, and Public Health Schools; Massachusetts General Hospital; MGH
Chelsea Healthcare Center; Dana-Farber Cancer Institute; Massachusetts College of Pharmacy & Allied
Health Sciences; Joslin Diabetes Center and Boston Medical Center. Key academic and cultural institutions in
the corridor include: Boston Latin School; Boston University; Emmanuel College; Harvard University; Isabella
Stewart Gardner Museum; Massachusetts College of Art and Design; Massachusetts Institute of Technology
(MIT); Museum of Fine Arts; Northeastern University; Simmons College; University of Massachusetts at
Boston (Umass Boston); Wentworth Institute of Technology; Wheelock College; and Winsor School. Many of

the medical and academic institutions in this area are members of the “Medical Academic and Scientific
Community Organization, Inc.” (MASCO). Large employers and other destinations in the corridor include
Assembly Square Mall, Biomed companies such as Genzyme Corporation; Boston Red Sox; Fenway Cultural
District; Gateway retail in Everett; Logan Airport; and Wellington Circle.
The City of Boston requires that major educational and medical institutions in Boston prepare, amend, and
periodically update and renew Institutional Master Plans (IMPs), which are comprehensive development plans
that describe an institution's existing facilities, long-range planning goals, and proposed projects. The process
brings the city and community into institutional planning, creates the possibility for a truly collaborative
approach to campus development, and offers institutions an opportunity to define their commitments to the
community for an extended period of time through a single comprehensive process rather than negotiating
such contributions and approval-by-approval. As a result of the deliberate, thoughtful, and cooperative
institutional master planning process, institutions in the Urban Ring corridor and throughout Boston have
uniformly adopted policies and practices that encourage auto travel reduction, travel demand management,
smart growth development, pedestrian and bicycle oriented growth, and support for transit use and
accessibility. These policies are all consistent with and strongly supportive of the Urban Ring Phase 2.
MASCO
The Medical Academic and Scientific Community Organization, Inc. (MASCO) consists of 21 institutional
members or associate members. MASCO plans, develops, and enhances the 213-acre Longwood Medical
and Academic Area (LMA) for the benefit of the general public and its members. MASCO's mission is to
pursue programs that promote a sense of community among its members, create and deliver services more
effectively, and lessen the burdens of government with regard to planning, development, and enhancement of
the LMA. MASCO creates and implements programs that assist the institutions and individuals in the LMA.
MASCO gets involved with facilitating the flow of traffic, coordinating development plans, serving as a liaison
with the Greater Boston community, and acting as a general community planner for the LMA. MASCO’s Area
Planning and Development strives to improve the accessibility and attractiveness of the LMA by providing
long-range planning, transportation planning, traffic and access improvements, and development and
construction coordination. Figure A-1 shows the extensive area that composes the Longwood Medical and
Academic Area.
The LMA is Boston’s densest employment center outside of downtown Boston. In September 2003, MASCO
published the State of the LMA: A Report on Longwood Medical and Academic Area Institutions, Their Future
Growth and Economic Impact.13 According to this report, the member institutions have strong concerns about
the limited direct transit options, the degree of traffic congestion, and the scarcity of parking (a particular
problem for clinical facilities). These problems complicate staff recruitment, discourage patients from seeking
medical treatment, and exacerbate tensions with nearby neighborhoods.
In response to the issues described in the report, the institutions have created state-of-the-art transportation
demand management (TDM) programs and currently spend well over $8 million annually on the MASCO
shuttle program, T-pass subsidies, and other transportation-related programs. All of the institutions are
strongly committed to encouraging their employees to use public transit. As of 2003, many institutions reported
reaching transit mode shares among employees of close to 50%, and most academic institutions reported that
roughly 75% to 100% of their off-campus students walk, bike, or use the MBTA due, in large part, to parking
prohibitions on campus. The MASCO report noted that the next round of significant mode share increases will
require significant transit improvements in the near term and major new transit investments such as the Urban
Ring over the long term. The institutions believe that public improvements must include increasing commuter
rail service at nearby Yawkey and Ruggles commuter rail stations, and providing more convenient access to
North Station, so that LMA personnel can increase their use of commuter rail. Many institutions, particularly
academic ones, reported that 25% to 30% of their staff and students walk or bike to campus from homes in

Even with MASCO’s large private investments (shuttle programs, transportation improvements, and
transportation demand measures (TDMs)), the Commonwealth’s investment in commuter rail service, transit
and other needed transportation infrastructure improvements have not kept pace with the growth of the LMA
area. The transportation goals that emerged from MASCO’s State of The LMA report fall into four broad
categories: transit access, pedestrians, traffic circulation, and parking, all briefly discussed below.
•
Transit access – MASCO’s successful shuttle bus services are considered a viable short-term strategy to
supplement MBTA services in the area. However, support from the public sector for additional transit
capability is critical to the success of MASCO’s transit goals for the future. MASCO supports moving
forward with the Urban Ring tunnel section that would directly connect the heart of the LMA to Green, Red,
and Orange Lines. It will also be critical to identify other east/west transit initiatives; nearer-term transit
improvements to the Green Line; improved scheduling of commuter rail service to Yawkey, Ruggles, and
Old Colony Stations; and feasible ways to introduce Urban Ring Phase 2 service to the LMA.

TECHNICAL TRAFFIC REPORT
•
Pedestrian realm – All major new development should make significant contributions to the vitality,
character, and accessibility of the pedestrian realm. The focus should be on adding pedestrian-friendly
retail, accessible entrance lobbies, and similar active uses in places like the hundred-percent corner at
Brookline and Longwood Avenues15 and along Huntington Avenue; converting service streets into
walkable streets with sidewalks and streetscape improvements where possible; and improving pedestrian
crossings at the Sears Rotary and other intersections. Above-grade pedestrian connectors could play a
critical role in the LMA and their feasibility and appropriateness should be studied.
•
Traffic circulation – Improvements should provide some relief for the LMA’s strained circulation system.
Options include circulation improvements to Ruggles Street, the Sears Rotary; the Riverway and
Longwood Avenues; evaluation of one-way pair streets; modifying traffic signal operations; and improving
management of deliveries. Circulation options should be evaluated on the basis of their ability to improve
traffic operations, while balancing open space, pedestrian and bicycle needs, as well as campus
circulation needs. Improvements that promote the use of bicycles, including on- and off-street dedicated
lanes and routes and secure storage, would improve access for employees and students.
•
Parking – The MASCO institutions remain firmly committed to encouraging alternatives to automobile
access through a wide variety of incentive programs. Parking ratios need to sufficiently address economic
needs for patient and visitor parking, while balancing employee demand for parking. It might serve the city,
the larger community, and institutions’ interests to explore more flexible performance-based management
approaches to minimizing peak hour traffic generation and parking demand.16
These goals are consistent with the Urban Ring project, and providing improved transit access and capacity to
the LMA is a major objective of the Urban Ring project.
In 2006, in response to the Boston MPO’s initial draft (November 2005) Regional Transportation Plan (Journey
to 2030), MASCO staff presented a memorandum (January 9, 2006) summarizing the LMA’s transportation
statistics and needs. Specific transportation needs identified by MASCO include:
•
Full time commuter rail service to Yawkey Station (including station improvements);
•
Full time commuter rail service to Ruggles Station;
•
Operational improvements on the D and E Green Line branches, including increased AM service to
better accommodate the 7:00 AM work shift, direct D Line service to North Station, schedule
adherence, and 3-car trains to increase capacity;
•
Station improvements at Kenmore, Fenway, and Longwood stations on the Green Line;
•
Improvements to Green Line central subway operations, including crossover tracks at Park Street
Station;
•
Transportation improvements in the Urban Ring corridor with the flexibility to reshape phasing and
alternatives, specifically a transit tunnel connecting Ruggles and Yawkey stations;
•
Improvements to the Sears Rotary and other area roadways to enhance pedestrian safety and improve
traffic flow;
•
Signal improvements to roadways in the area and funding for Boston’s Traffic Management Center
(monitor and correct deficiencies with real time traffic information);
•
Public bicycle parking;
•
Improved pedestrian connections, particularly to transit nodes; and

Congestion Mitigation and Air Quality (CMAQ) funding for TDM programs in the LMA.
At MASCO’s annual meeting, Massachusetts Transportation Secretary Bernard Cohen announced
Commonwealth initiatives, through the 2006 Economic Stimulus Bill, to invest $35 million in traffic, roadway,
and public transit improvements around the LMA. Some of the initiatives Cohen outlined are $12 million to
make Yawkey Station a full-service commuter rail station, $5 million to enhance the Longwood and Fenway
stations on the D line, $5.6 million for traffic management improvements, and $12.5 million for improvements
to roadways and pedestrian walkways. The community will have the opportunity to review plans and provide
input. Some projects are already underway. The Boston Transportation Department (BTD) is currently
conducting a $400,000 traffic improvement survey in the Longwood and Fenway areas. In addition, EOT will
use an additional $500,000 to study and create a preliminary design of a commuter rail and multi-modal
transportation center in Allston. Urban Ring project plans are coordinated with these improvements.
Beth Israel Deaconess Medical Center (BIDMC)
Because of strong fiscal year 2007 financial results, BIDMC was able to increase its capital budget for fiscal
year 2008 to include additional funds to be spent on equipment, technology and buildings. Specifically, BIDMC
launched the planning for a major renovation/building project, designed to increase clinical capacity at the
main LMA campus and enhance convenience and access for patients at a new BIDMC ambulatory care center
at a yet-to-be-determined suburban location. Additional clinical capacity will increase the demand for transit
travel in this vicinity. The Cardiovascular Institute at Beth Israel Deaconess was also launched to better serve
patients, coordinate care, and use common electronic medical records to enhance service to patients.
Brigham and Women’s Hospital
Brigham and Women’s Hospital completed a five-year Institutional Master Plan (IMP) and Article 80 for a new
10-story, 350,000 square foot clinical care facility with 150 beds (the Cardiovascular Center) at 70 Francis
Street. The facility will feature publicly-oriented facilities on the first and second floors and three below-grade
levels of parking. The IMP also approved restoration and enhancement of the historic Brigham Green and
below-grade parking project, as well as open space, pedestrian, and transportation improvements. The IMP
ensures the zoning compliance of preexisting institutional buildings and uses, and provides limited preapprovals for future leases for institutional purposes of sites within and without the LMA.17 Planned
development at Brigham and Women’s Hospital will benefit from future transit improvements, including the
Urban Ring Phase 2 project.
Children’s Hospital Boston
Children's Hospital Boston's July 2006 Strategic Plan identified an urgent need for new inpatient beds to serve
its growing acute care patient population. The hospital also identified the need for several LMA campus
development and improvement projects over the next ten years to provide sufficient clinical, research and
hospital support space. Because potential long-term plans are not finalized and the need for acute care beds
is so urgent, Children's IMP currently only includes a proposed vertical 60,375 square foot addition to its Main
Building, providing 39 new inpatient beds.
The additional traffic generated by the Main Building Expansion Project will have minimal impacts to the
transportation infrastructure and minor incremental impacts to the transit operations in the area by 2018. To
offset these new trips, Children’s is committed to providing transportation improvements and mitigation actions
to improve transportation for patients, visitors, and employees traveling to the LMA. The hospital will continue
to proactively manage its drop-off and valet parking operation at its main entrance to reduce traffic activity on
area streets, particularly along Longwood Avenue. Children’s is committed to implementing visitor TDM
measures to encourage the use of alternative modes of transportation. In addition, Children’s will continue to
expand its proactive TDM measures to its employees to encourage the use of transit and other alternative

forms of transportation. As part of this plan, Children’s has introduced a parking rate structure that makes it
advantageous for employees to park outside of the LMA and ride shuttles to the campus.
The IMP analysis assumed that future Children’s employees, patients, and visitors will have access to the
many public transportation services offered by the MBTA, as well as the array of private shuttle and TDM
services that are offered in the LMA through MASCO. The IMP notes, however, that some existing public
transportation services will be operating at or above capacity during peak periods by 2018 if services are not
expanded to meet expected passenger demands.18
Harvard Medical, Dental and Public Health Schools
Harvard University completed an IMP for its medical school campus in the Longwood Medical and Academic
Area of Boston. The IMP provides for the long-range renovation of the buildings and grounds of the School of
Public Health, the School of Dental Medicine, and the Medical School at the Harvard University Longwood
Medical Campus. Through a combination of demolition, renovation, and new construction over a 10-year
period, five new buildings, an underground parking garage, new landscape, and new quadrangle will take
shape.19 Harvard has plans to construct a new 53,000 square foot School of Dental Medicine and Research
Education Building, and several smaller projects. The building projects are required to reduce overcrowding in
existing facilities and to meet the immediate need for state-of-the-art research space for the Dental School.20
Harvard University’s School of Medicine also participated in a neighborhood development partnership for a
mixed-use project called One Brigham Circle. The partnership also included Partners Healthcare, New Boston
Fund, Inc., NDC Development Associates, Inc., Mission Hill Neighborhood Housing Services and the Mission
Hill community.21 One Brigham Circle is located adjacent to the LMA in the Urban Ring study corridor. Mixed
use developments in urban areas such as this one with limited on-and off-street parking encourage the use of
public transit.
Massachusetts General Hospital (MGH)
Massachusetts General Hospital is working on an Article 80 for the development of a 10-year Institutional
Master Plan for the MGH campus development. Over a ten-year period, the MGH proposes a new
construction and off-campus leasing plan to address the three components of its mission: patient care,
education and research. The document describes projects that would accommodate these goals, as well as
administrative and parking issues.22
Currently in the works is preparation for the construction of MGH's Building for the Third Century (B3C). Three
buildings (the Clinics, Vincent Burnham Kennedy (VBK) and Tilton) are currently being demolished to prepare
the site for construction of the new, 530,000-square-foot clinical facility, which is scheduled to be completed in
2011.23 Urban Ring Phase 2 connections to the existing radial transportation system, including connections to
the Kendall/MIT Station on the Red Line, will be important for enhancing transit connectivity for this and other
development projects on the MGH campus.

TECHNICAL TRAFFIC REPORT
Dana-Farber Cancer Institute (DFCI)
Dana-Farber Cancer Institute completed its IMP in December of 2006. The transportation chapter in the plan
presents a summary of the existing transportation aspects of DFCI and develops a thorough description of its
transportation infrastructure 10 years into the future. It is based on the comprehensive Transportation Access
Plan that was developed in connection with the Center for Cancer Care Draft Project Impact
Report/Environmental Impact Report (DPIR/DEIR), which was filed simultaneously with the IMP. The IMP
presents a set of mitigation strategies and improvement measures that will provide transportation
improvements to the LMA.
DFCI plans to implement six projects over the course of the IMP. Of these projects, the following two will affect
parking conditions on the campus:
•
Renovation of DFCI’s existing Dana Building will include reconfiguration of an existing above-grade
structured parking area and surface vehicular drop-off/pick-up area into approximately 71,000 SF of
administrative/institutional space. The existing 213 parking spaces and vehicular drop-off area located
within the existing Dana Building will be relocated within the new Center for Cancer Care facility (described
below).
•
The Center for Cancer Care project includes construction of a single building project totaling approximately
257,500 zoning square feet (ZSF)24 of space at 450 Brookline Avenue. The proposed project will create
approximately 219,049 ZSF of “net new” construction to accommodate much needed clinical and clinical
research space. It will also include some ground floor retail space, and a campus dining area. The new
building will serve as the campus’ main entrance along Brookline Avenue, and provide public pedestrian
access via entrances along both Brookline Avenue and Jimmy Fund Way. It will also include provision of a
new below-grade drop-off and valet parking area that will be integrated into the existing Smith Building
parking facility. All of DFCI’s on-campus parking will be located within this garage upon completion of the
project. The project (including the Dana Building renovation) will result in 217 net new parking spaces.
The comprehensive transportation improvement and mitigation plan proposed by DFCI IMP will provide an
improved transportation infrastructure for patients, visitors, and employees traveling to the LMA. DFCI will
proactively manage the creative, underground drop-off and valet parking facility as a means to reduce traffic
activity on area streets, particularly along Brookline Avenue. DFCI is also committed to reconstructing the
intersection of Brookline Avenue/Jimmy Fund Way/Deaconess Road/Joslin Place to allow for a safe and legal
left-turn for motorists traveling southbound on Brookline Avenue toward the DFCI campus. DFCI will set its
new building back to allow for the creation of wide pedestrian sidewalks along both Brookline Avenue and
Jimmy Fund Way and to create an additional left-turn lane from Jimmy Fund Way onto Brookline Avenue.
DFCI is also committed to improving existing traffic cameras in the area and to the installation of a new pantilt-zoom camera at the Brookline Avenue/Jimmy Fund Way intersection. Roadway improvements and
enhanced valet parking operations management have been devised to help manage peak hour traffic flow
adjacent to the site. DFCI will also continue to expand its proactive TDM to its employees to encourage the
use of transit and other alternative forms of transportation.25 In addition, providing retail and dining facilities on
the ground floor of the project may help eliminate some auto trips and encourage the use of public transit.

Boston Medical Center (BMC)
Boston Medical Center26 recently filed an Environmental Notification Form (ENF) for a new 245,000 square
foot, nine-story Ambulatory Care Building at 725 Albany Street (the site of the current 91 East Concord Street
building). The project will allow the relocation and consolidation of several outpatient services currently located
in BMC’s Doctor’s Office Building (DOB) and the Dowling Building (two existing on-campus buildings), and will
require demolition of the existing aging Maternity Building at 91 East Concord Street. The shift in the location
of the existing ambulatory functions does not result in a significant increase in the square footage of outpatient
services on the campus. However, the project is anticipated to generate 1,996 new daily trips, and will result in
a decrease of five parking spaces. BMC submitted an Institutional Master Plan Notification Form/Project
Notification form to the BRA on April 30, 2007. An Institutional Master Plan Amendment/Draft Project Impact
Report was submitted to the BRA on August 22, 2007. The project ENF provided the following transportationrelated mitigation measures and benefits:
•
Upgrade of the streetscape along the proposed project site to establish a more pedestrian-friendly
edge to the BMC campus and improvement of pedestrian crossing experience at Albany Street;
•
Removal of significant patient and employee traffic from Harrison Avenue;
•
Maintenance of the public link through the BMC west campus area to the neighborhood;
•
Provision of building setbacks that improve sidewalk space around 725 Albany Street; and
•
Provision of transportation demand management programs (shuttle services, carpool, hybrid car,
emergency ride home, MBTA pass, and car sharing programs).27
All of these improvements will encourage the use of transit and non-motorized modes of transportation in the
LMA. The project is undergoing review by the BRA under Article 80 of the Boston Zoning Code.
Boston University (BU)
Boston University began the update and renewal of BU’s 1997 IMP in 2002. The process involved a task force
of 16 community groups with dialogue among BU, its neighbors, and the City of Boston. The Master Plan
includes development projects the university would like to complete over the next 10 years. Ranging from
immediate goals at the time, like construction of the Life Science and Engineering building, renovation of the
Nickelodeon and the graduate student apartments at 580 Commonwealth Avenue, to more distant ones, like a
new School of Law building, the process entailed BU, the community, and the city casting a consensus about
the size and shape of the university’s growth.28
Beginning in 2006, Boston University has conducted a new master planning effort focused on the long-term
development of the Charles River Campus. In December of 2006, Boston University’s Strategic Planning
Coordinating Task Force completed One BU: A Connected University Framework of a Strategic Plan: 20062016. One of the 12 core commitments of the strategic plan states: “We will pursue changes in our built
environment… that will help to define and integrate the campuses, facilitate informal gatherings and study
sessions, (and) make the campuses pedestrian- and neighborhood- friendly.”29 A 2001 article in the Boston

Globe featured Commonwealth Avenue near the BU bridge (see photo below) as one of the most dangerous
areas in Boston for pedestrians.30
In November of 2007, based on feedback from One BU and a subsequent plan entitled Forging Our Future by
Choosing to Be Great, BU released it’s 2007 Strategic Plan: Choosing to Be Great: A Vision of Boston
University – Past, Present, and Future.31 This document focuses on the fundamental level of values, vision,
and a plan to achieve BU’s goals. A key concept in the Commonwealth Avenue/BU Bridge study is tying
together a campus that is stretched along Commonwealth Avenue by creating a new central hub at the
intersection of Commonwealth Avenue and the BU Bridge. A BU study of improvements to this location
recommended that state and city planners consider building near the BU Bridge a transportation hub that
would connect the existing Commuter Rail line to the Green Line and to rapid transit buses traveling along the
proposed Urban Ring, connecting Boston’s universities and medical centers. The proposed transit hub would
benefit BU and neighboring communities by providing faster and more convenient transportation to about
70,000 residents of Cambridge, Boston, and Brookline. It would create an opportunity to design a more
pedestrian-friendly flow of traffic in the area of the BU Bridge, and encourage the development of commercial
and retail space, as well as institutional space to meet the needs of the University without requiring an
expansion into neighboring communities. The long-term advantages of such a hub would include providing a
new center of gravity pulling East and West Campuses together, and reconnecting with the Charles River.
Such a concept could be a powerful incentive for new academic, residential, and commercial development
with improved traffic flow, safety, and other urban benefits.32
Ideas from the BU study involving connections to the Urban Ring have been presented to the EOT, which has
incorporated this planning into the Urban Ring Phase 2 project recommendations. In turn, University will
coordinate several current and proposed roadway improvement projects with the state’s master plan for the
Urban Ring.

Harvard University
Harvard has been filing IMPs for its existing Allston campus since 1989. On January 11, 2007, Harvard
unveiled a vision for its future, filing with the City of Boston a proposed IMP for the first stage of the physical
evolution of an interdisciplinary campus in Allston. The Plan describes two phases. Phase 1 refers to those
Harvard development projects and related infrastructure improvements that are expected to occur over
approximately the next 20 years. The second phase, involving potential build-out over the ensuing 30 years, is
more speculative and is included to provide a more complete vision of the potential for redevelopment in
Allston. Phase 1 of the development program, which includes between 4 and 5 million gross square feet of
new space including academic space, housing, museums, and a conference center, was the primary subject
of the January 2007 filing. The plan states that an integrated, multimodal transportation system will be
essential for the long-term success of Harvard’s proposed development in Allston. Key transportation goals for
Phase 1 are:
•
Protecting and enhancing the interface between the campus and the neighborhood;
•
Addressing the transportation requirements of the planned projects and providing connectivity with
Harvard’s other campuses;
•
Fostering sustainable development that relies as little as possible on the private automobile; and
•
Improving the connections between Allston and the region.

TECHNICAL TRAFFIC REPORT
As part of Harvard’s large-scale expansion into Allston, Harvard University also proposed siting a commuter
rail station at the current location of the Beacon Park Rail Yard.33
The transportation component of Phase 1 of Harvard’s IMP is multimodal in nature, addressing highway,
public transportation, bicycle, and pedestrian needs. The ultimate transportation requirements will be important
considerations in establishing the long-term development framework for Allston and will provide a major
contribution to the overall sustainability of the Allston development program. Phase 1 projects are consistent
with the transportation elements of the broader planning framework for North Allston. Most significantly, this
broader framework incorporates guidelines set forth through the North Allston Neighborhood Strategic Plan
(NANSP) process and the Boston Transportation Department’s (BTD) priorities for Harvard development in
North Allston.34
Under the proposed IMP, Harvard will improve city streets, with new pedestrian walkways, bicycle lanes, and
plantings.35 Harvard’s IMP discusses bike access, public transit, proposed new Harvard shuttle services
(between Allston and Cambridge and between Allston and the LMA), Transportation Demand Management
(TDM), parking, vehicular traffic access, existing roadway conditions, and preliminary trip generation and
distribution estimates. However, detailed analyses of the potential traffic impacts for the Phase 1 development
program have not been completed at this time. Harvard anticipates refining the study area for the Phase 1 IMP
with BTD and Boston Redevelopment Authority (BRA) and conduct traffic impact analyses at locations where
changes in traffic patterns due to the project and construction of surrounding streets may occur.36
Northeastern University
Northeastern University is working under a 10-year IMP that lays out development proposals through the year
2010. Northeastern University’s 2000 Master Plan was amended in August 2004 surrounding Building F and
the Coventry Street property. In 2006, The BRA approved a change to the IMP that allowed for 1,800 new
residence-hall beds and the opportunity for some non-residential development. The BRA also allowed
Northeastern to incorporate some recently purchased properties in the IMP, and approved the first phase of
residential construction, a 1,200-bed hall at the corner of Tremont and Ruggles Streets. The next phase of
residential construction is a 600 residential bed dormitory on the site of an existing Northeastern building on
St. Botolph Street in the Fenway.
In order to maximize community input to its master planning process, Northeastern joined with representatives
of the Fenway, Mission Hill and Roxbury neighborhoods in the Northeastern University Community Task Force
under the auspices of the BRA. The task force hammered out a proposal for new residence halls during 46
meetings through 2005 and 2006. The first phase residence hall will consist of two towers, one 19 stories and
the other 23 stories. It will also hold a dining hall, ground-floor retail space, and 30,000 square feet of office
space to replace offices now in Cullinane Hall. The residence hall is slated to open for fall 2009.37 Additional
students living on Northeastern’s campus will benefit from improved transit connections provided by the Urban
Ring Phase 2 project.

UMass Boston is in the process of updating their 25-year Campus Master Plan. The existing conditions portion
of the effort was presented for Master Plan Subcommittee review in July 2007, and the UMass task force is
currently looking at future plans and alternatives. Phase I of the plan (5-10 years) will include new academic
buildings, 1,000 beds of residence hall space, structured parking, and modifications to circulation and open
space. The development of the new Master Plan will focus on facilities expansion and rehabilitation, establish
design guidelines (buildings, sustainability, parking and transportation), resolve sequencing of individual
project, and identify funding sources.38 These improvements will also benefit from improved transit
connections at the JFK/UMass MBTA station provided by the Urban Ring Phase 2 project.
Massachusetts Institute of Technology (MIT)
MIT is a diverse educational community with a dense, highly organized environment of experimental,
intellectual, social, and recreational activities. Rapidly approaching the saturation of its available spaces, the
Institute confronts the planning challenge of furnishing a master plan with sufficient muscle and flexibility to
accommodate both current and as yet only emerging demands. In response to an urgent need for new
campus housing, in 1999 MIT developed a Master Plan for a new residential corridor forming the Vassar
Street edge along Briggs Athletic Field. To meet the changing needs of teaching and research, the Institute is
adding an array of new facilities. The School of Management’s new home, scheduled for completion in 2010,
will extend from Memorial Drive to Main Street and will serve as an eastern gateway to the MIT campus. Also
in construction and slated for occupancy in spring of 2008 is a graduate residence complex that will expand
the northwest sector of MIT’s campus housing quarters. A new cancer research facility to be located next to
the David H. Koch Biology Building and across from the Eli and Edythe L. Broad Institute is scheduled to begin

The Master Plan for the east campus was assigned as a joint venture to Gruzen and PartnersMitchell/Giurgola. Their scheme is designed to connect and integrate the previously disparate main and Sloan
campus sectors.39
Each year, MIT publishes Reports to the President that include annual reports of MIT's academic and
administrative units, summarizing the year's goals, accomplishments, honors and awards, and future plans.
The Office of Institutional Initiatives (OII) was established on July 1, 2005, with the mission of managing the
development program for the highest-priority interdisciplinary initiatives at MIT. To achieve this goal, the office
works with colleagues within Resource Development; with school, program, and project fundraisers; with the
MIT Alumni Association; and with selected faculty and staff. In fiscal year 2006, OII worked with faculty leaders
and administrators to develop the fundraising architecture for the new facility for the MIT Center for Cancer
Research.40 Increased development will result in increased demand for transit ridership.
Wentworth Institute of Technology (WIT)
In the fall of 2005, WIT launched a strategic planning process called “Building the Next 100 Years” to plan how
to best respond to industry needs by evolving the existing and developing new undergraduate programs. The
Institute has a tradition of working very closely with the community, which it is doing now through its new
Center for Community & Learning Partnerships. In October 2005, WIT opened a residence hall at 555

Simmons College
Simmons College is currently undergoing a new strategic planning process. The College has $103 million
approved and funded for Phase III of their Master Plan for facilities to address long-term issues. Recent
projects include major library renovation, construction of a new School of Management building, campus quad
and underground parking facility (to completed in January 2009), and expansion of the Fens Dining facility in
the Main Campus Building (to begin in spring 2008). The Fens Dining facility project will include renovations to
the College’s loading dock and shipping and receiving areas, plus completion of an underground link between
the new parking garage and the Main College Building.42
Emmanuel College
In 1996, Emmanuel College led the discussion to initiate the Colleges of the Fenway (COF), an innovative
consortium of six neighboring colleges. Since the COF's founding, Emmanuel has offered its students the
social and academic benefits of a large university while maintaining the close-knit community of a small private
college. Also in 1996, the College developed its Institutional Master Plan to identify tangible, achievable ways
for Emmanuel to significantly increase its enrollment and thrive in the new century. The 1996 Master Plan
identified a strategy for funding, and sketched the ways Emmanuel's academic and residence life facilities
would evolve in the years ahead. The Master Plan accommodated a one hundred percent increase in
academic facilities while “greening” the campus and relocating surface parking to peripheral structured
parking.
The Master Plan identified two parcels of lease-able area (an "endowment campus") that could secure a
sufficient revenue stream for growth without affecting the quality of its academic program. In 2000, city and
state regulatory agencies approved both the campus master plan and the endowment campus plan.43 The
College then entered into a 75-year ground-lease agreement with a private company, enabling them to
construct a 400,000 square-foot research facility in exchange for a one-time multi-million dollar payment.44
Wheelock College
Wheelock submitted its Institutional Master Plan to the BRA in February of 2007. It was subsequently reviewed
and discussed at community meetings, including meetings with the LMA Forum and the Community Task
Force established as an advisory body for both the BRA and Wheelock. BRA Board approved Wheelock
College’s 10-Year Institutional Master Plan on May 31, 2007. The plan included a 129-bed student housing
facility and two potential projects that would add new housing, academic, and administrative uses to the
Fenway campus.45

During the 1988-89 school year, the existing Boston Latin School building underwent a complete renovation,
including major work on the auditorium and cafeteria, an extension that added a new gymnasium and ancillary
athletic facilities, and new computer and science labs. From 1999 to 2002 the building was once again
renovated and upgraded to the latest in technology, and a new library was built within the space once
occupied by the cafeteria, and a new building with art and music rooms and a new dining hall was
constructed.47
Winsor School
Winsor School’s Board has been engaged in strategic planning for the past two years, considering the future
needs, opportunities, and challenges of the school. They have been exploring to best pursue the school’s
mission in the future. The LMA is one of the city’s most rapidly developing neighborhoods, making the
possibility of expansion on the current campus more difficult. The master planning process is investigating the
potential for expanding their existing Pilgrim Road campus, including potential underground construction, as
well as considering land acquisition and assessing alternative sites that might provide more options. In the
mean time, the school has undertaken renovation and athletic field projects.48
Isabella Stewart Gardner Museum
The Board of Trustees of Boston’s Isabella Stewart Gardner Museum adopted a Master Plan in 2003. The
Museum is committed to the importance of intimate scale and personal sensibility, and their master planning
process reflected that. In November 2004, the museum announced a plan to preserve the historic palace and
support expanded programs for visitors, artist, schools and community partners, including a new building on
the Museum’s property. The new building is part of a larger campaign to preserve Isabella Gardner's historic
Palace, world-class fine art collection, and legacy.
The Museum initiated the Article 80 Development Review process with the Boston Redevelopment Authority
(BRA) for the proposed new building in November of 2004. Located behind the Museum’s historic Palace in
the Fenway, the proposed new building will improve the visitor experience and provide much-needed space to
address the critical conservation, programming, and administrative needs of the institution. The design
includes approximately 60,000 square feet, including: an orientation area, a performance hall, a special
exhibition gallery, studio classrooms, improved greenhouses, a café, an expanded museum shop, visiting
artists’ accommodations and studio space, new conservation labs, and administrative offices. The new
building will incorporate sustainable design initiatives, including a geothermal well system. The design for the
new building will open up the site to the public, providing a more inviting and safer entrance along Evans
Way.49

Regional Plans and Policies
Several regional organizations are significantly involved with the Urban Ring project. The following is a
summary of the planning coordination activities between the project and the Circumferential Ring Regional
Planning Compact, comprised of six of the municipalities along the Urban Ring Project Corridor; the Boston
Metropolitan Planning Organization (MPO); the MBTA; and the MAPC.
Circumferential Ring Regional Planning Compact
The six municipalities that formed the Compact in 1995 adopted a set of planning principles and committed
themselves to working with the MBTA during the Urban Ring project. The six communities act as a regional
collaborative in the Urban Ring corridor. By sharing information, working together to resolve transportation
issues, and advocating for solutions that serve the interest of the entire corridor, their intent is to support and
coordinate transportation and land use along the corridor in a manner which best serves each community as
well as the whole. The Compact is also focused on protecting the environment and neighborhoods from
negative growth impacts. The Compact has pledged to integrate land use, planning, and zoning initiatives with
transit planning, and to support ridership on new transit services, as described in the Urban Ring Compact
Final Draft Report.50
Metropolitan Area Planning Council (MAPC)
MAPC is the regional planning agency for the Boston metropolitan area. The MAPC has recently completed a
major regional planning called MetroFuture: making a Greater Boston Region. Initiated in May 2002 and
completed in 2008, the MetroFuture team incorporated the public’s ideas about what the region’s future should
look like under the guidance of a Steering Committee. The team developed the following four scenarios based
on Metro Boston’s growth and development through 2030:51
Current Trends – Let It Be: The first scenario is the “Let it be” scenario which shows what Metro Boston
might look like in 2030 if the current trends continue. In this scenario, the existing problems get worse, with
sprawls, unaffordable housing, educational inequity and unsustainable water withdrawals.
Alternative 1 – Little by Little: The first alternative demonstrates what the region might look like if cities and
towns implement many of the “smart growth” tools.

Alternative 2 – Winds of Change: This scenario illustrates what the region might be like if communities
made major efforts to address challenges regionally, with individual cities and towns sharing in the costs and
benefits of growth.
Alternative 3 – Imagine: The final scenario address the changes after the communities prioritize responses
st
to 21 century global challenges such as climate change, energy independence, and growing international
economic competition.
The MetroFuture vision for the Boston metropolitan area calls for planning and land use policies that reduce
sprawl, concentrate residential and commercial development in existing urban areas, and protect open space
and natural resources. These policies are consistent with and supportive of the proposed Urban Ring Phase 2
project.
The following major topics are discussed in MAPC’s MetroFuture Regional Plan:52
Existing Land Use and Projected Growth – The Urban Ring corridor is home to two major medical centers and four
universities. In 2001, the area provided 327,400 jobs and was home to 392,700 residents.53 Growth trends
indicate that jobs and residents will continue to increase. MAPC projections suggest that jobs in the Boston
Metropolitan Region may increase by 12.4 percent from 2000 to 2030, and 41 percent of this growth will occur
within the “inner core” cities of Boston, Cambridge, Somerville, Revere, Everett, and Chelsea. Based on
historic trends in birth rates, mortality and migration, MAPC anticipates a 13 percent increase in residents in
the region between 2000 and 2030, with 35 percent of this growth occurring in the inner core cities. Transit use
along the Urban Ring corridor would continue to be the highest in the region.54
Corridor Land Use Policies – Land use policies along the Urban Ring Project Corridor have been established to
help meet the needs of each community. While communities such as Everett, Chelsea and Somerville are
looking to promote development in underutilized zones, Boston and Cambridge look to focus their growth in
established economic areas, while preserving residential neighborhoods.
Tools to Implement Land Use Policies – Federal, state and local governments have all made pledges to invest in
targeted areas along the Urban Ring Project Corridor. Whether through infrastructure improvements or lease
commitments, an effort has been made to focus funds along the corridor.
Performance of Land Use Policies – The communities have distinguished four types of areas, each with specific
land use policies: neighborhood business centers, established areas, emerging areas and residential areas.
The performance of land use policies in each of these areas is analyzed and the potential impact of the Urban
Ring project is assessed.
Transit-Supportive Regulations Near Transit Stations – Through unique zoning and other regulations, each
community has encouraged transit use along the Urban Ring system. For example, specific parking
regulations, transit-oriented development and other policies aimed directly at increasing transit ridership have
been established to ensure that transit ridership will reach higher levels.
Containment of Sprawl – The Compact communities are working to create a regional policy to contain sprawl.
They support limiting suburban growth and focusing future economic development along and within the Urban
Ring Project Corridor.

TECHNICAL TRAFFIC REPORT
Boston Region Metropolitan Planning Organization (MPO)
The MPO has developed the current long-range transportation plan for the Boston region that includes the
transportation policies that will help guide the development of the Urban Ring goals and objectives.
The MPO’s Mobility Management System (MMS), formerly known as the Congestion Management System
(CMS), is an ongoing program for monitoring mobility in the region, providing the MPO and transportation
planners with timely information about transportation system performance, and making recommendations in
the areas where mobility deficiencies are found. The MMS program includes the systematic measurement and
analysis of mobility problems in the region so that they may be mitigated. The staff then provides decisionmakers with information about transportation system performance and with strategies and recommendations
for improving mobility.
The annual Unified Planning Work Program (UPWP) is a federally required certification document describing
transportation planning projects. It describes transportation planning studies undertaken by the MPO and other
entities in the Boston region during a given federal fiscal year. It provides information to government officials,
local communities, and the general public about all of the transportation planning studies that are expected to
occur in the region, and complete budget information to federal and state officials. Information from the MMS
and associated planning studies funded through the annual UPWP are used in the selection of projects for the
Plan and the Transportation Improvement Program.
The MPO recently completed the Boston Region MPO Transportation Plan Journey to 2030,55 which consists
of policies, topics, and visions for transportation in the region over the next 23 years. The Plan was prepared
according to guidelines outlined under Safe, Accountable, Flexible, Efficient Transportation Equity Act: A
Legacy for Users (SAFETEA-LU). The policy topics are related to the eight planning factors in the SAFETEALU and are also consistent with the objectives of the Patrick/Murray Administration. The Journey to 2030
document recommends the Urban Ring Phase 2 project.
Massachusetts Bay Transportation Authority (MBTA)
The MBTA has developed a 25-year capital planning document, Program for Mass Transportation (PMT),
which sets forward the Authority’s vision for public transportation in eastern Massachusetts. The 2003 PMT
defines a vision for regional mass transportation and sets priorities (high, medium, or low) for infrastructure
investments in the areas of system preservation, service enhancement, and system expansion. The Urban
Ring project Phase 2 and 3, including the Silver Line Phase III expansion to South Station and Boylston via
Chinatown, the Silver Line south extension to Ashmont and Mattapan, the Green Line extension, and the
Red/Blue connector have been identified as the projects with the highest priority for implementation.
The PMT has formulated the following goals to implement its 25-year vision for public transportation in the
Massachusetts Bay region:
•
Preserve and modernize the transit system and improve accessibility;
•
Improve mobility for area residents and visitors now and in the foreseeable future;
•
Minimize transportation-related pollution of the environment;
•
Promote the equitable sharing of the transportation system’s benefits and burdens; and
•
Serve as a partner for community development within the MBTA service area.

Regional Plans and Policy Summary
The Compact municipalities have fully incorporated the Urban Ring project into their future transportation and
growth plans. The Boston MPO has incorporated Phase 2 of the Urban Ring project into the Boston Region
MPO Transportation Plan, Journey to 2030.56 The MBTA has identified the Urban Ring project as one of the
projects with the highest priority for implementation, and the MAPC encourages “smart growth” tools for the
Greater Boston Region. The Urban Ring Project Corridor will be used to encourage controlled growth, which
will meet the criteria established by the entire region for smart growth.
State Plans and Policies
The 1994 State Transportation Bond Bill passed by the legislature and signed into law contains authorization
for conducting environmental studies for the Urban Ring. The MBTA is responsible for determining the need
for transportation improvements in the corridor and eventually progressing any identified projects through the
environmental process. In September 1996, the MBTA issued its Service Delivery Policy as approved by the
MBTA Board of Directors. The purpose of the Service Delivery Policy is to ensure that MBTA service meets
customers’ needs and is provided in a cost-effective manner. While other state-level agencies and authorities
have transportation responsibilities that sometimes relate to the Urban Ring, those agencies are generally
focused on other modes.
The Commonwealth of Massachusetts Executive Office of Transportation and Public Works Office of
Transportation Planning develops transportation plans, programs, and projects to advance the transportation
policies and objectives of the Secretary of Transportation and to ensure compliance with federal and state
transportation and environmental laws and regulations so that federal transportation funding to Massachusetts
continues. The Office of Transportation Planning performs the following activities to accomplish its mission:57
•
Develop multimodal and modal-specific statewide transportation plans, and project-specific
transportation improvement programs.
•
Inform and seek input from both the public and private sector in their efforts to improve the
transportation system.
•
Ensure a certified federally-mandated transportation planning process through oversight and active
involvement in the Commonwealth’s Metropolitan Planning Organizations.
•
Monitor, analyze, and report the functional and fiscal performance of the Massachusetts
transportation system.
•
Develop and implement statewide management systems to identify transportation needs, issues, and
strategies for improvement.
•
Perform and manage project-level Major Investment Studies, corridor planning studies, traffic
planning studies, and freight planning studies.
•
Design and manage innovative transportation programs, such as travel demand management, open
space, intelligent transportation system planning, transportation enhancements, alternative fuels,
scenic byways, bicycle and pedestrian planning.

On September 1, 2000, the state Department of Environmental Protection (DEP) entered into an
Administrative Consent Order (ACO) with the Executive Office of Transportation and Construction (EOTC, now
EOT); that ACO and its subsequent amendments establish requirements and deadlines for environmental
filings for the Urban Ring. The MEPA unit of the Executive Office of Environmental Affairs (EOEA) is the
regulatory body charged with ensuring that the Urban Ring filings are submitted by their deadlines and that
they comply with state environmental laws and policies.

Air Act Amendments
The Massachusetts Department of Environmental Protection (MassDEP) has implemented programs to attain
the ambient air quality standards in the 1990 amendments to the federal Clean Air Act. The state is required to
monitor ambient air to determine if it meets a standard. If it does not meet a standard, it must develop and
implement pollution control strategies. State plans and control strategies constitute the State Implementation
Plan (SIP).
State Implementation Plans (SIP)
MassDEP has SIPs for ozone, carbon monoxide, nitrogen oxides, and air pollution transport. The final
Massachusetts SIP revision to meet Federal Clean Air Act Air Pollution Transport Requirements was
completed in January 2008, The Urban Ring project would result in an overall improvement in air quality in the
region.
Greenhouse Gas Reduction Policies
In 2007, the Executive Office of Energy and Environmental Affairs (EEA) issued a Greenhouse Gas Emissions
Policy and Protocol to take all feasible measures to avoid, minimize, or mitigate damage to the environment
Page 27

URBAN RING PHASE 2
TECHNICAL TRAFFIC REPORT
due to project greenhouse gas emissions.58 The Urban Ring project would reduce indirect greenhouse gas
emissions by reducing overall traffic generation in the region.
State Rideshare Regulations
The Massachusetts Rideshare Regulation (310 CMR 7.16) is part of the Commonwealth’s plan to reduce air
pollution and to achieve and maintain health-based federal air quality standards. It requires many businesses
with 250 or more commuters and educational facilities with 1,000 or more commuters to develop commuter
option programs aimed at reducing drive-alone trips.59 The Urban Ring provides a viable commute alternative
to the single occupant automobile.
Smart Growth and Sustainable Development Strategies
The Urban Ring project is consistent with the Commonwealth’s Smart Growth and Sustainable Development
strategies. At the end of 2003, draft transportation evaluation criteria were developed to apply to transit and
highway projects. The criteria have been used to:
•
Develop regional transportation plans and TIPs;
•
Manage resources in state agencies; and
•
Assist proponents in the project initiation process.
The following three project types have been identified for transit and highway projects as part of the evaluation
criteria:
•
Preservation;
•
Improvement; and
•
Expansion.
The Patrick Administration has shown strong support for proposed transit expansion projects such as the
Green Line Extension project. The Patrick Administration released the South Coast Rail Plan in April 2007 to
bring commuter rail services to southern Massachusetts communities. This Administration has also supported
Smart Growth development initiatives such as Transit-Oriented Development (TOD). A major new TOD
initiative was launched by the MBTA in partnership with Office of Commonwealth Development (OCD)
agencies to support planning efforts that will result in additional housing and revenue to support transit. The
OCD recently developed guidelines entitled What is Transit-Oriented Development?
The OCD will encourage the coordination and cooperation of all agencies in Smart Growth and will be guided
by the following development principles:
1.
Redevelopment First;
2.
Concentrate Development;
3.
Be Fair;
4.
Restore and Enhance the Environment;
5.

The current administration is promoting sustainable development through integrated energy and environment,
housing and economic development, transportation and other policies, programs, investments, and
regulations. The state will encourage the coordination and cooperation of all agencies and stakeholders, invest
public funds wisely in smart growth and equitable development, give priority to investments that will deliver
good jobs and good wages, transit access, housing, and open space.60 The Urban Ring Phase 2 project
promotes these goals.
2006 Economic Stimulus Bill
An Economic Stimulus Bill (ESB) was passed by the Democratic majority-held Legislature in the summer of
2006. This bill allocates portions of the state budget to improvements intended to stimulate economic growth in
Massachusetts. This legislation appropriated approximately $152 million to Massachusetts development and
research/technology programs to “promote job creation, economic stability, and competitiveness in the
Massachusetts economy.” The Urban Ring project provides improved transit access for such development.
Economic development results in a greater demand and need for improved public transit, public safety, access
to public transportation facilities and services, and compliance with the Americans with Disabilities Act. The bill
covers transportation improvements, including road, pedestrian, and infrastructure projects, and specifies
planning, design, and construction projects in downtown Boston and in the vicinity of the Urban Ring corridor.
Some of these projects include:
•
Traffic management, including new and improved signals and traffic management equipment for
Brookline Avenue, Boylston Street, Beacon Street, Commonwealth Avenue, Melnea Cass Boulevard, and
Ruggles Street.
•
Investigate the improvement of traffic flow in and around the Longwood Medical, Fenway and Kenmore
Square areas, and all intersecting streets and roadways, including, but not limited to, an analysis of: (i)
use of variable one-way lanes during peak traffic hours; (ii) peak-time traffic restrictions and bus and
ambulance priority lanes; (iii) permanent reconfiguration of two-way streets to one-way streets; and (iv)
partial or complete elimination of on-street parking on Brookline Avenue and other streets and roadways.
•
Construction of a Back Bay Connector in the Allston Landing area in the City of Boston.
•
Enhancements to the Fenway, Kenmore and Longwood stations on the MBTA Green Line.
•
Planning, design and construction of a new eastbound crossover tracks at Park Street Station and a
dynamic double berthing information system.
•
A study of the feasibility of building a tunnel for the Silver Line to travel under D Street in the City of
Boston.
•

Transportation Bond Bill
On April 17, 2008, Governor Patrick signed a $3.5 billion transportation bond bill to invest in road and bridge
projects across the Commonwealth over three years. Portions of the Urban Ring alignment may benefit from
this legislation.
Commonwealth Capital Programs
The recently updated Commonwealth Capital Policy coordinates state capital spending programs in order to
invest in projects that are consistent with the Commonwealth’s Sustainable Development Principals and to
partner with municipalities seeking to advance shared conservation and development interests.62 The policy
encourages communities to site and build homes and businesses in ways that conserve energy and natural
resources. The programs encourage local implementation by linking state spending programs to municipal
land use practices. The Transit-Oriented Development Bond Program is a Commonwealth Capital Program.
In July 2007, Governor Patrick announced six guiding principles for the state’s transportation agencies. These
guidelines set new vision for transportation policy in Massachusetts. They include:
1.
Aligning transportation initiatives with environmental goals;
2.
Improving coordination among agencies and improving transparency;
3.
Improving project delivery;
4.
Fostering economic growth through enhancements and modernization of the transportation system;
5.
Addressing the shortfall in transportation funding and restoring financial stability; and
6.
Addressing perceived geographic inequities in the funding of transportation projects and services
across the state.
The Commonwealth Capital Programs encourage redevelopment and new development in areas already
served by infrastructure; preserve and protect historic structures and critical lands; and reward and encourage
local land use planning that supports the commonwealth’s Sustainable Development Principles.
Transit-Oriented Development (TOD) Guidelines
The TOD Bond Program was authorized by Massachusetts Legislature in 2004 and is intended to increase
compact, mixed-use, walkable development close to transit stations by providing financing for pedestrian
improvements, bicycle facilities, housing projects, and parking facilities within 0.25 miles of commuter rail
subway, bus or bus rapid transit station, or ferry terminal.63 The Urban Ring project benefits from this
legislation.

Federal Plans and Policies
With the mission to provide fast, safe, efficient, and convenient transportation at the lowest cost, the United
States DOT has set policies to improve safety throughout the transportation network; reduce congestion for
better performance of the Country’s transportation system; increase global connectivity to open international
transportation markets and improve intermodal transportation linkages; address environmental challenges to
provide safe and efficient transportation network; and provide security, preparedness and response to both
expected and unexpected transportation challenges.65
Federal policies most relevant to the Urban Ring project are those of the Federal Transit Administration (FTA)
within the United States Department of Transportation (DOT). The FTA’s discretionary New Starts program is
the Federal government’s primary financial resource for supporting locally-planned, implemented, and
operated major transit capital investments. From heavy to light rail transit (LRT), from commuter rail to bus
rapid transit (BRT) systems, the New Starts program has helped to make possible dozens of new or extended
transit fixed guideway systems across the country. These rail and bus investments have improved the mobility
of millions of Americans, helped to reduce congestion and improve air quality in the areas they serve, fostering
the development of more viable, safe, and livable communities.66
st
In late 2003, Congress passed a short-term extension of the 1998 Transportation Equity Act (TEA) for the 21
Century (TEA-21) to February 29, 2004 as it continued to work on a new 6-year reauthorization. On May 22,
2006, The 1998 TEA-21 has since been replaced by the new act called Safe, Accountable, Flexible, Efficient
Transportation Equity Act: A Legacy for Users (SAFETEA-LU). The SAFETEA-LU was signed into law by
President Bush on August 10, 2005. On February 14, 2007, Federal Highway Administration (FHWA) and FTA
published the “Final Rule.” According to the Final Rule, statewide and metropolitan transportation planning and
programming are required to implement the provisions of SAFETEA-LU.67 The SAFETEA-LU mandates that

TECHNICAL TRAFFIC REPORT
proposed transit New Starts projects must receive FTA approval to advance from alternatives analysis (e.g.
the Urban Ring MIS) to preliminary engineering, and again from preliminary engineering to final design and
construction. This approval will be based, in large part, on an evaluation of the proposed project against the
FTA New Starts criteria.68 FTA issued updated New Starts and Small Starts guidance on policies and
procedures on June 4, 2007, and New Starts/Small Starts Evaluation Measures on August 3, 2007.69
SAFETEA-LU requires this guidance be updated at least every two years.70
In 2008, the US DOT and FTA published its Annual Report on Funding Recommendations, Proposed
Allocations of Funds for Fiscal Year (FY) 2009. This document provides the U.S. Department of
Transportation’s recommendations to Congress for the allocation of funds for the design and construction of
fixed guideway New Starts and Small Starts capital investments for FY 2009. New Starts and Small Starts
programs are part of the Capital Investment Grant Program provisions most recently reauthorized by the
SAFETEA-LU in August 2005. As required by SAFETEA-LU, the annual report document also contains a
summary of the allocation of funds made available in FY 2007 to assist qualified projects under the Alternative
Transportation in Parks and Public Lands program.71
The FTA has implemented various planning-related programs to support transit, including Alternative
Transportation in Parks and Public Lands; Public Transportation Participation Pilot Program; Transit Oriented
Development/Joint development; Transportation Planning Capacity Building Program; and Travel Model
Improvement Program.
Additionally, the policies and criteria of several other federal agencies are also potentially relevant because of
the relationship of the Urban Ring project to land use, economic development, and Brownfields
redevelopment. The US DOT has developed a policy that encourages transportation officials to pay for the
cleanup of environmental contamination that lies in the path of a transportation project, as well as continue a
program of support for the United States Environmental Protection Agency’s (U.S. EPA’s) Brownfields
Economic Redevelopment Initiative. TEA-21/SAFETEA-LU also encourages, through the integrated planning
process outlined in the statute, the integration of transportation projects with environmental and community
revitalization goals. As such, TEA-21/SAFETEA-LU fits well with US DOT policy regarding Brownfields
Redevelopment.
There are several industrial areas within the Urban Ring Project Corridor, such as in Chelsea and Everett,
which may be revitalized though the Brownfields initiatives to improve transportation access. US DOT
agencies, including FTA, encourage transportation agency project sponsors to develop their transportation
improvement programs in concert with contaminated site remediation and redevelopment efforts at targeted
Brownfields sites.

Traffic Count Data
Traffic count data was collected from a variety of sources. The specific source of traffic count data used for
each study intersection is shown in Table B-1.
For Urban Ring Phase 2 study intersections with outdated count data or where no counts were available, new
traffic turning movement counts were collected. New intersection turning movement counts were collected at
79 study intersections between December 14, 2006 and May 2, 2007. Traffic count data worksheets are
provided in the Technical Traffic Report Additional Supporting Materials document. Intersection turning
movement counts were performed between 7 and 9 a.m. and 4 and 6 p.m. on weekdays, which represent the
peak commuting periods.

Updated counts (Ruggles Street) were completed by VHB/MASCO on November 28-29, 2006 to account for new
traffic volumes as a result of the re-opening of the Ruggles Station busway accessible from Ruggles Street. This
is part of MASCO’s work with BTD to improve signal timing in this corridor. VHB/MASCO completed counts on
Tremont Street in March 21, 2006 as part of an ongoing signal improvement project.

TECHNICAL TRAFFIC REPORT
D.
Study Area Private Shuttle Service Data
The corridor is served by a number of private transportation services, primarily consisting of
shuttle and circulator bus routes provided by a number of the major institutions, employers, and in
one instance, a major shopping mall. The private shuttles typically provide specialized
connections for employees and students when those origins and destinations are generally not
well-served by the MBTA. While MBTA bus routes may serve some origins and destinations
served by shuttles, they may not provide a one-seat ride as many of the shuttles do. The services
are focused primarily in the Boston and Cambridge portions of the corridor, and operate with
fleets of both passenger vans and full size transit buses. Private shuttles are provided for several
major employment areas in the Urban Ring corridor, including the Longwood Medical and
Academic Area (LMA), Mass General Hospital, Kendall Square, UMass Boston, Boston
University and Medical Center area, MIT, and Harvard. Employer shuttles are often provided as
part of Transportation Management Associations (TMAs). Some of these in the corridor include
MASCO, MIT, and Partners. Some shuttles, such as the MASCO M2 Route, are open to the
public who are not employees, patients or students, but may require payment. In some instances
tickets may not be sold on the vehicle.
The private transportation systems in the corridor provide feeder service between activity centers
and existing transit stations and line-haul service between major nodes. An example of the former
is the UMass shuttle between the JFK Red Line Station and the nearby UMass-Boston campus.
An example of the latter is the shuttle between the Harvard Medical School in the LMA of Boston
and Harvard Square in Cambridge. The private shuttle providers have identified a need for
service not currently provided adequately by public transit. With an absence of improved public
transit service for crosstown trips in the corridor, it can be expected that travel demand for both
types of private transportation service will increase given the forecasted growth in corridor trip
making between 45 and 55 percent over existing levels.
The total daily ridership of the private shuttles in the study area is approximately 36,850 trips
(year 2007). The service provider with the highest ridership is UMass Boston (the shuttle between
UMass and the JFK/UMass Red Line station), which has 13,000 daily riders, followed by MASCO
(approximately 9,440 daily riders) Partners Health Care (6,540 daily riders), and Boston
University (3,570 daily riders).
Tables D-1 and D-2 compare the percentage overlap among private shuttle routes and the
proposed BRT routes for 2030 Build and Hybrid and LPA alternatives, respectively. Several
private shuttle routes have a high percentage of overlap with the Urban Ring routes, including
UMass Boston Routes 1 and 2, which both experience high ridership today. This indicates that
there may be an opportunity for the Urban Ring project to provide services to the areas where
BRT routes overlap with private shuttle services. For routes with a high percentage of overlap, it
is reasonable to expect that many current riders on private shuttles could shift to Urban Ring BRT
service. In these cases, reduction or elimination of the private shuttle route could be considered,
which would reduce the volume of bus trips on study area roadways. It is noted that private
shuttles support travel needs between campus locations and off-site parking.

Numbers show the percentage of private shuttle routes covered by BRT routes in the Urban Ring Study Corridor.
UMass = University of Massachusetts, Boston
MASCO = Medical Academic and Scientific Community Organization, Inc.
BU = Boston University. BU also operates a fleet of Healthnet buses that travel to neighborhood health centers in the Boston Area. This service is intended only for patients, therefore it is not included here.
CRTMA = Charles River Transportation Management Association
MIT = Massachusetts Institute of Technology.
There are several Harvard University Shuttles that provide inner services. Here, only one shuttle, the “Soldier’s Field Road Shuttle” is considered as it overlaps with the Urban Ring services.

Numbers show the percentage of private shuttle routes covered by BRT routes in the Urban Ring Study Corridor.
UMass = University of Massachusetts, Boston
MASCO = Medical Academic and Scientific Community Organization, Inc.
BU = Boston University. BU also operates a fleet of Healthnet buses that travel to neighborhood health centers in the Boston Area. This service is
intended only for patients, therefore it is not included here.
CRTMA = Charles River Transportation Management Association
MIT = Massachusetts Institute of Technology.
There are several Harvard University Shuttles that provide inner services. Here, only one shuttle, the “Soldier’s Field Road Shuttle” is considered as
it overlaps with the Urban Ring services.

URBAN RING PHASE 2
TECHNICAL TRAFFIC REPORT
E. Traffic Volume Calculations
Traffic volume calculations are described below for existing, No-Build, and Build conditions.
Existing Traffic Volumes
The existing traffic volumes used for this study come from a combination of collected data and traffic data
from CTPS, local municipalities, and agencies. Turning movement counts collected by others were used if
the data was more recent than 2002. Any counts collected between 2002 and 2006 were adjusted upward
to 2006 based on calculated traffic growth rates. Traffic growth rates were calculated by comparing new
traffic volume data at nearby intersections with older data at the same location (generally 2002 vs. 2006
volumes), where available. Based on the comparison results, the following composite annual traffic
growth rates were calculated for each community:
Boston
Brookline
Cambridge
Chelsea
Everett
Medford
Somerville
-0.2%/year
Not available
-0.2%
Not available
-0.8%/year
Not available
-1.8%/year
As shown above, traffic volumes have decreased over the last several years.
For intersections with older count data or where no counts were available, new traffic turning movement
counts were collected or developed. New intersection turning movement counts were collected at 79
study intersections between December 14, 2006 and May 2, 2007 (see Section B of this report).
No-Build Traffic Volumes
Year 2030 traffic and transit forecasts were developed by CTPS based on the MPO’s regional
Transportation Plan, Journey to 2030. The land use, employment and demographics of the plan were
used to develop travel forecasts in the region, including the Urban Ring study area.
A three-step process was used to develop year 2030 No-Build traffic volumes for capacity analysis
purposes. The first step was to take the year 2030 CTPS traffic volume projections and compare those
with the CTPS 2006 baseline traffic model volumes to develop annual traffic growth rates for each study
intersection approach (northbound, southbound, eastbound, and westbound directions). While a wide
range of traffic growth rates were observed, the annual traffic growth from 2006 to 2030 generally ranged
between -10 and +15 percent. Based on this information, traffic growth factors were developed to
represent CTPS model growth between 2006 and 2030. Traffic growth rates for No-Build traffic volume
calculations are provided at the end of this section.
The growth factors were applied to the year 2006 Existing Conditions traffic count volumes (both roadway
and intersection turning movement volumes) to develop Future 2030 traffic volumes. To provide a
conservative analysis, only positive growth rates were used for future volume projections. For intersection
approaches showing negative or growth rates less than 6 percent between 2006 and 2030, a default
growth rate of 6 percent (=0.25 percent per year for 24 years) was assumed. The following represent

average future annual growth rates used to project 2030 traffic volumes for intersections within each
community:
Boston
Brookline
Cambridge
Chelsea
Everett
Medford
Somerville
1.5%/year
0.5%/year
2.0%/year
1.9%/year
1.0%/year
0.9%/year
1.6%/year
The second step involved a post-processing procedure where projected turning movements were
compared with existing and projected future volumes (from others) that reflect known potential
developments in the study area. Based on these comparisons, adjustments were made to the projected
year 2030 intersection turning movement volumes. The major sources for comparison of future traffic
volumes in the project study area included:
•
Year 2011 Synchro Traffic Model, Boston Transportation Department, 2006;
•
Synchro Traffic Model, City of Cambridge;
•
Dana-Farber Cancer Institute Center for Cancer Care Study (2016 Build Condition);
•
Blackfan Research Center/New Blackfan LLC Study (2009 Build Condition);
•
Beth Israel Deaconess Medical Center Longwood North Research Center Draft PIR (2013 Build
Condition);
•
Harvard University Study for Stadium Way Extension in Allston;
•
North Point Final EIR (2014 Build Condition);
•
Northeastern University Institutional Master Plan (2010 Build Condition);
•
Fenway Neighborhood Transportation Plan (2007 traffic volume projections – 40 percent drive
option);
•
Master Plan EIR, Everett Avenue Urban Revitalization and Development Project, Chelsea, April
30, 2001;
•
Assembly Square Impact Study (2025 preferred alternative);
•
Somerville Ikea Expanded ENF (2006 Build Condition project trips);
•
Boston University Charles River Campus Transportation Master Plan, 2002; and
•
BioSquare Phase II FEIT, 2004.
Traffic volumes from these documents were extrapolated as necessary to be consistent with the Urban
Ring’s 2030 future analysis year.
CTPS model land use projections were updated in September and December of 2007, resulting in
increased population and employment primarily in the LMA, Allston, and East Somerville. To account for
these changes, intersection and roadway volumes at some locations required further adjustment. This
was accomplished through a comparison of previous CTPS projections to the new CTPS projections. If
total intersection volume change was greater than 20 percent (positive or negative), adjustments were
made to traffic volumes based on the percent difference between previous and updated CTPS volumes.

URBAN RING PHASE 2
TECHNICAL TRAFFIC REPORT
The third and final step in the process was reviewing traffic volume balance of adjacent intersections, and
providing adjustments as appropriate. The process of developing the 2030 No-Build volumes was
coordinated with and overseen by the Urban Ring Phase 2 project Citizens Advisory Committee (CAC)
Traffic Subcommittee.
Build Traffic Volumes
The traffic volumes for the Urban Ring Baseline and Build Alternative conditions are based on projected
growth in traffic demand throughout the corridor resulting from future population and employment
projections, along with impacts from specific developments and traffic growth assumptions in certain
congested areas of the corridor. The future Build traffic volumes were reduced slightly from the No-Build
traffic volumes to account for mode shift from automobiles to Urban Ring service. The Build traffic
volumes used in this RDEIR/DEIS are generally conservative, and represent a consistent and reasonable
basis for evaluating a range of future traffic conditions. The specific methodology to estimate future Urban
Ring Phase 2 Baseline and Build Alternative traffic volumes follows.
Urban Ring Phase 2-generated weekday commuter peak hour bus volumes were developed for the
Baseline Alternative, the nine Build Alternatives, the three Hybrid Alternatives, and the LPA based on the
proposed routes and headways (see Section G). To be conservative, no replacement of existing bus or
shuttle service by the Urban Ring was assumed for this analysis.
The next step in the development of Build Alternative traffic volumes was adjustment of the 2030 roadway
volumes based on mode shift comparison from the CTPS model forecasts with and without the project.
The travel demand forecasts showed that the Urban Ring LPA project would reduce the number of
automobile trips in the region by approximately 24,000 auto trips per day compared with the Baseline. The
percentage vehicle reduction due to the project was calculated for each study roadway and then applied
to the corresponding intersections. At study intersections, the peak hour automobile trip reduction created
by the project was generally between 0.25 and 0.33 percent.
To create the 2030 Build (with project) peak hour traffic volumes, the 2030 No-Build traffic volumes were
adjusted for mode shift and then added to the calculated Urban Ring bus volumes. The process of
developing the 2030 No-Build and Build traffic volumes was coordinated with and overseen by the CAC
Traffic Subcommittee. Build condition traffic volume calculation back-up data is provided at the end of this
section.

Description of Future Roadway Projects
Future roadway projects are described below.
Infrastructure and Expansion Projects Opened Since 2000, Under Construction, or Programmed
for 2007 in TIP:72
•
Central Artery Project (Boston);
•
Massachusetts Avenue/Lafayette Square Roadway Realignment (Cambridge); and
•
Cambridgeport Roadways Realignment.
These projects, which are included in the 2030 No-Build alternative, are described briefly below.
Central Artery Project (Boston) – The Central Artery project is an 8-10 lane, limited-access, 1.5 mile
long underground expressway that has replaced the formerly elevated I-93 through the center of Boston.
It also includes the Ted Williams Tunnel from South Boston to Logan Airport, and extension of I-90 from
near South Station to Logan Airport and Route 1A in East Boston; four major highway interchanges; a
able-stayed bridge across the Charles River; and the reconstruction of an additional 2.1-mile segment of
I-93. In all, the project includes construction or reconstruction of 161 lane-miles of urban highway, about
half in tunnels, in a 7.5 mile corridor.
Mass Ave/Lafayette Square Roadway Realignment (Cambridge) – This project realigns the
intersection of Mass Ave/Main Street/Columbia Street to form a four-way intersection opposite Sidney
Street. The project also requires realignment of the traffic signal.
Cambridgeport Roadways Realignment – Street patterns in Cambridgeport from Mass Ave to Memorial
Drive will be realigned, including Sidney Street, Waverley Street, Albany Street, and Brookline Street. The
benefits of the project include traffic flow improvements, the diversion of traffic away from neighborhood
streets, and economic development opportunities.
The Boston Region MPO’s Transportation Plan, Journey to 2030, is the primary source for identifying
what new roadway improvements or expansions will occur by the project’s 2030 design year. The
following infrastructure and expansion projects in the Plan are regionally significant, located in or near the
Urban Ring Project Corridor, and were assumed for the 2030 future analysis scenarios:
Infrastructure and Expansion Projects in the Recommended Journey to 2030 Plan73
•
East Boston Haul Road/Chelsea Truck Route (Boston);
•
Route 1A/Boardman Street Grade Separation (East Boston);
•
Rutherford Avenue/Sullivan Square Reconstruction (Boston);
•
Logan Airport Consolidated Rental Car Facility (East Boston);
•
River’s Edge Boulevard (formerly Telecom City Boulevard, Everett, Malden, and Medford);
•

TECHNICAL TRAFFIC REPORT
•
Route 1 Improvements (Malden and Revere);
•
Mahoney Circle Grade Separation (Revere);
•
Route 1/Route 16 Interchange (Revere);
•
Route 1A/Route 16 Connection (Revere); and
•
Interstate 93/Mystic Avenue Interchange (Somerville).
These projects are described briefly below.
East Boston Haul Road/Chelsea Truck Route (Boston) – The East Boston Haul Road/Chelsea Truck
Route will utilize an unused former railroad ROW between Frankfort Street and Chelsea Street Bridge.
The project as defined in the RTP 2007 is intended to remove truck traffic from East Boston residential
streets. It would also be used by other commercial vehicles and MBTA buses. This facility will enable the
Urban Ring service in East Boston to utilize a limited access facility between Logan Airport and the
Chelsea Street Bridge. Intersection improvements at the intersection of Frankfort Street and Chelsea
Street are proposed as part of the Urban Ring project.
Route 1A/Boardman Street Grade Separation (East Boston) – This project involves construction of an
overpass with ramps to replace the existing signalized intersection of Route 1A and Boardman Street.
Boardman Street will be relocated approximately 400 feet south of its current location and Route 1A traffic
will pass over Boardman Street, with connections provided via on- and off-ramps.
Rutherford Avenue/Sullivan Square Reconstruction (Boston) – The Rutherford Avenue project is
intended to improve alignment and function of Rutherford Avenue in Charlestown in the context of the
completion of the Central Artery/Tunnel project. The project includes a redesigned Sullivan Square to
accommodate enhanced development opportunities and improved pedestrian connections between the
Charlestown neighborhood and the Sullivan Square MBTA station. The City of Boston completed a
planning study in 1999 that included preliminary concepts for roadway system reconfiguration in Sullivan
Square and along Rutherford Avenue; the City of Boston is currently conducting a preliminary design
process to develop roadway improvements that are expected to be somewhat different from the
proposals in the 1999 study.
Logan Airport Consolidated Rental Car Facility (East Boston) – This project consists of a
Consolidated Rental Car Facility (ConRAC); a commercial parking facility; and an environmentallyinnovative passenger bus system connecting airline passengers with both parking and rental car modes.
The project will be constructed on airport property known as the Southwest Service Area, and is intended
to create an efficient and environmentally superior facility that will help meet current and future ground
access needs.
River’s Edge Boulevard (formerly Telecom City Boulevard, Everett, Malden, Medford) – This project
includes constructing a two-lane, median-divided roadway between Santilli Highway in Everett and
Corporation Way in Medford, with a bridge across the Malden River. The new road will accommodate
public traffic and will improve access among the three communities.
Revere Beach Parkway (Route 16 Everett, Medford and Revere) – This project consists of providing a
six-lane mainline parkway between Route 38 in Medford and Sweetser Circle in Everett, except for a fourlane section at Wellington Circle. Wellington Circle will be replaced with a single-point diamond
interchange, with Route 16 passing underneath.
Route 1 Improvements (Malden and Revere) – As part of this project, Route 1 is widened from four to
six lanes between Copeland Circle (Route 60) and Route 99, and the on- and off-ramps at Salem Street
and Lynn Street will be reconstructed to provide acceleration/deceleration lanes, better turning radii, and
full turning movements. Also, the connection between Route 99 and Route 1 will be improved by
providing a normal right-lane merge from Route 99 northbound to Route 1 northbound.

TECHNICAL TRAFFIC REPORT
Mahoney Circle Grade Separation (also known as “Bell Circle, ”Revere) – The preferred alternative
or this project will remove the rotary by relocating a portion of Route 1A and depressing Route 60 under
Beach Street. Access to local streets will be maintained via direct connections from a newly constructed
Beach Street Connector.
Route 1/Route 16 Interchange (Revere) – This project provides a direct connection from Route 1
southbound to Route 16 eastbound and from Route 16 (Revere Beach Parkway) westbound to Route 1
northbound. The improvements include a signalized double left-turn lane from Route 1 southbound onto
Route 16 eastbound and a standard on-ramp from Route 16 westbound to Route 1 northbound.
Route 1A/Route 16 Connection (Revere) – This project involves a realignment of Route 16 (Revere
Beach Parkway) and its junction with Route 1A to the south, placing a three-fourths-cloverleaf
interchange at the northwest corner of Suffolk Downs. A new signal will be installed on Route 16
providing left turns from Route 1A southbound to Route 16 eastbound. A traffic signal will be installed at
the intersection of Route 16 and Winthrop Avenue (Route 145), and the current alignment of Route 16 will
be closed north of Route 145 and converted into a linear park.
Interstate 93/Mystic Avenue Interchange (Somerville) – Includes a new underpass separating Route
28 northbound, and converting the existing underpass to the exclusive use of Route 28 southbound. A
new connector road will be constructed between Mystic Avenue and Middlesex Avenue, and the I-93
northbound off-ramp will be reconstructed to permit the connector road to Assemble Square.

Urban Ring Phase 2 Bus Volumes
Urban Ring Phase 2-generated bus volumes were developed for the Baseline Alternative and the nine
Build Alternatives. Tables showing Bus volumes for these future Build conditions are provided in the
Technical Traffic Report Additional Supporting Materials document.
Weekday commuter peak hour BRT and CT bus volumes were identified for the future study roadways
and intersections based on the proposed routes and headways. The highest Urban Ring bus volumes
occur on roadways where multiple BRT routes travel on the same alignment, plus CT routes. Roadway
examples include Chelsea (Eastern Avenue), Cambridge (Kendall Square), and Boston (Melnea Cass
Boulevard, and Ruggles Station). The following six study intersections would experience in excess of 36
BRT (60') buses during the weekday commuter peak hours:
•
Eastern Avenue/Chelsea Bridge (Chelsea);
•
Eastern Avenue Bellingham Street (Chelsea);
•
Eastern Avenue/Griffin Avenue (Chelsea);
•
Arlington Avenue/Sixth Street (Everett);
•
Ruggles Street/Station Entrance (Boston); and
•
Melnea Cass Boulevard/Washington Street (Boston).
Projected Urban Ring bus volumes on roadways and at intersections vary (+/-) depending on the
alternative. At tunnel locations in Alternatives 3 and 4, bus volumes are lower than the same locations
with surface alignments (e.g., Alternatives 1 and 2). To be conservative, no replacement of existing bus or
shuttle service by the Urban Ring was assumed for this analysis.
It is important to note that the projected Urban Ring bus volumes would represent only a small proportion
of the total traffic volume on study roadways, generally less than two percent. The volume of new buses
would also be far below the general traffic growth projected on most roadways in the study area.
Therefore, the proportion of bus traffic (including Urban Ring service) compared with total traffic volume
may actually decrease.
As part of the traffic capacity analysis performed for the Urban Ring Build scenario, a passenger car
equivalency (PCE) factor was utilized to account for the proposed buses within the roadway network.
This factor was based on whether a proposed bus would be part of mixed traffic or traveling along an
exclusive bus-way or lane. For a bus within mixed traffic, a PCE of 3 passenger cars per 1 bus was
used. This is based upon the 60-foot length of a proposed bus, and an average car length of 20-feet. For
a bus traveling within an exclusive bus-way or lane, a PCE of 1 was used, but the Heavy Vehicle
percentage within the analysis was changed to 100.

Bus Signal Priority System Information
Traffic signal priority is proposed for the signalized intersections along the roadway sections of the Urban
Ring Phase 2 Bus Rapid Transit System. Signal priority has been proposed to reduce delays for buses at
traffic signals and improve overall bus travel time and reliability compared to the existing traffic signal
systems in the corridor that currently do not have the priority feature. Traffic signal priority works by
modifying signal timing to provide an operating advantage to buses traveling through signalized
intersections in order to improve bus travel time and reliability along their routes. The Build alternative
includes traffic signal priority for buses operating in exclusive busways, bus lanes, and mixed traffic when
operating through signalized intersections. Current practice in traffic signal bus priority was identified
through research into technical literature, review of best practices, and discussions with traffic signal
equipment suppliers as well as discussions with the MBTA and City of Boston Transportation Department
staff relative to experience on the Silver Line.
Traffic Signal Priority Strategies
Traffic signal priority strategies can involve either passive or active strategies, defined as follows:
•
Passive priority only acknowledges the presence of the bus in terms of the timing pattern; the
predetermined timing pattern is not affected by the presence of buses. This involves changing the
signal timing at a group of intersections to favor buses. This can be done by adjusting the cycle
length, split phases, and giving priority to buses in area wide timing plans. These strategies favor bus
flow without actually detecting the presence of the bus. Passive strategies do not involve equipment
cost; they only involve engineering and minimal implementation costs.
•
Active priority occurs when a signal from a bus overrides the existing pattern and substitutes a new
signal pattern to benefit the bus. Priority can be divided into unconditional and conditional subsets.
Unconditional priority (known as preemption) is similar to that practiced at railroad grade crossings,
whereby the green phase is granted whenever a bus requests it, subject only to clearance intervals
required for safety. Conditional priority considers other factors such as progression, time since last
preemption, and whether the bus is on or behind schedule before priority is granted. Most cities with
bus priority systems have utilized conditional priority; this is deemed to be most appropriate for the
Urban Ring Phase 2 bus routes.
•
Bus movements can also be expedited by coordination of signals along an arterial street without
specific priority for buses. Coordination of arterial flow would benefit buses as well as general traffic.
This is recommended for all corridors in the Urban Ring network as well as utilizing signal priority.
Traffic Signal Priority Benefit and Impacts
Traffic signal priority will reduce delays for buses at signalized intersections, but can also increase delays
for traffic on cross street approaches. Recognizing this, the effects of traffic signal priority were first
tested in the Urban Ring Phase 2 DEIR, November 2004 using the SYNCHRO software program for 12
prototypical intersections around the corridor selected in collaboration with the municipalities. The
prototypical intersections were selected to represent a range of LOS and geographic conditions.
SYNCHRO is a software program that analyzes traffic flows through signalized and unsignalized
intersections. It is based on the methods of the Highway Capacity Manual (HCM) published by the
Transportation Research Board. SYNCHRO was used to estimate the reduction in delay on the bus
approaches and increase in delay on the cross street approaches. This was done for increases of 5, 10
and 20 seconds of green time on the bus approaches. The benefit for buses was measured for a cycle in
which a bus was present while the impact on side streets was determined for an average cycle (over a 1
hour period) since priority will not occur every cycle. The results are shown in Table I-1.
Page 145
November 2008
URBAN RING PHASE 2
TECHNICAL TRAFFIC REPORT
As can be seen from Table I-1, reductions in bus delay are greater for intersections with worse LOS and
lesser for those with better LOS. The average reduction in bus delay for a green time increase of
10 seconds ranges from 70 percent for LOS F to 35 percent for LOS B. As can also be seen from Table I-1,
generally the cross street delay increases as the added time for buses is increased. The cross street delay
generally increases least for better baseline LOS and most for worse LOS. The average increase in cross
street delay for a green time shift of 10 seconds ranges from 75 percent for LOS F to 5 percent for LOS B.
For Baseline LOS A, B, or C; generally the reduction is no worse than LOS D. For Baseline LOS D, E, and
F, the increase in delay and reduction in LOS is greater, generally in the LOS E/F range.
Comparing the results of the travel time savings for the bus approaches and the increased delays for the
cross street traffic, it can be seen from Table I-1 that the travel time savings is generally a greater
percentage improvement than the travel delay increase on the side streets.
The impacts shown in Table I-1 to cross street delay are given in terms of vehicle delay at the
intersections. A review of the technical literature and experience in other locations indicates that traffic
signal bus priority can also be justified in terms of savings in person delay rather than strictly vehicle
delay. Since the buses are projected to carry large numbers of passengers and most automobiles will be
carrying low numbers of passengers, reducing delays for buses will reduce overall person delay at the
intersections even if some cross street delays are increased. This also needs to be considered in
identifying the strategy for traffic signal, bus priority.
Further, research into experiences in other cities which have implemented traffic signal bus priority
indicate actual results are quite favorable for both improvement in bus delays and impacts on general
cross street traffic. Evaluation of traffic signal bus priority systems in Los Angeles and Seattle shows as
much as 25 percent decrease in delay for buses at intersections with priority and minimal increases in
delay to cross streets. This result is attributed to the design of the systems, which limits the extra green
time for buses to 10-15 seconds per bus and also limits the priority requests to successive buses to allow
the intersections to recover. These results indicate that the theoretical SYNCHRO results in the attached
table may be very conservative, i.e. worse compared with national industry results, since it does not
reflect the recovery cycles for the cross-street traffic.
Figure I-1 shows transit travel times improvement in 13 cities in U.S. and abroad after the implementation
of transit signal priority. It shows that the 13 cities experienced 1.5 to 15 percent improvement in bus
travel time due to transit signal priority. These cities included a variety of transit service types under
varying traffic conditions.

Transit Travel Time Improvements with Transit Signal Priority

Systems, Benefits, Costs and Deployment, and Lessons Learned. 2008 Update.
During the DEIR process, (based on discussions with the Traffic and Transportation Subcommittee of the
CAC) it was determined that the bus priority strategy should emphasize improvement of bus travel times
without major impact on cross street traffic. It was recommended that the largest increment in bus green
times take place at the intersections with better levels of service in order to minimize the effects on cross
street traffic. In order to address this recommendation, three ITS strategies were developed and tested to
determine their effects.
Three levels of ITS bus signal priority techniques (1, 2 and 3) were identified with ITS 1 being the least
aggressive in terms of additional green time and ITS 3 being the most aggressive. Table I-2 summarizes the
additional green time by LOS grade for bus approaches at signalized study intersections. The additional
green times for each ITS strategy were applied to all signalized study intersections in the Urban Ring
corridor according to the average delay savings developed from the prototype intersections. The results
were then summarized for each ITS strategy to determine the travel time savings for each BRT route.
The analysis results show that ITS 1 would reduce travel time by approximately 1 percent over baseline
Build conditions. For ITS 2, travel time savings ranged between 5 to 20 percent within an overall average
savings of approximately 10 percent. For ITS 3, travel time savings increased up to approximately
30 percent for some BRT routes.
Based on the travel time savings, intersection delay results, and expected increased ridership for the
DEIR (+12,250 daily riders), ITS 2 was recommended for the Recommended Build alternative for the
morning and afternoon peak periods74. ITS 1 was not selected because of its marginal benefits. ITS 3 is

not recommended due to its negative impact on side street traffic delay and practicality of implementation
during peak periods. Table I-3 shows the travel time savings for the DEIR Recommended Build with ITS 2
compared with the MIS Build with and without ITS 2. Except for BRT 7, which shows a negligible increase
in travel time, each of the BRT routes reduces travel time over the MIS Build between 9 and 35 percent.
BRT 7 is slightly slower in the Recommended Build than the MIS Build due to additional station stops.
The ITS 2 strategy refers to traffic operations during peak traffic periods. As described above, maximum
green time increments for bus priority will be based on peak hour traffic LOS. At off peak periods,
however, it may be possible to provide some or greater signal priority where it is not possible due to poor
peak hour operations. The proposed traffic signal system will have the capability of detecting actual traffic
demand and making a determination of whether and what extent priority is possible at all periods of time
during the day. For this reason, it is recommended that all Urban Ring intersections be equipped for
possible signal priority even if projected peak hour traffic operations do not permit such operation. The
decision whether to grant priority will be determined on a real time basis depending upon detection of
actual traffic demands.
The selection of the signal priority approach depends upon the number of buses that are candidates for
priority, number of buses adversely affected by priority, impact of priority on general traffic and pedestrian
flow, and concurrent priority on crossing streets. Suggested requirements in the technical literature for
conditional bus priority to be effective are: a minimum of 100 buses per day; or a minimum of 10-15 buses
per hour in the peak hours. Maximum bus volume for conditional priority is approximately equal to half the
number of hourly traffic signal cycles. Above the maximum bus volume, passive signal timing plan priority
may be more effective. Most of the Urban Ring routes have appropriate numbers of buses per hour in the
range for implementing conditional bus priority. In areas where bus volumes are greater than this
threshold, consideration should be given to passive strategies during peak hours when bus volumes are
large and active strategies at other off peak times.
Traffic Signal Priority Equipment and Implementation
In order to implement conditional bus priority using the ITS2 strategy at traffic signals along the Urban
Ring bus routes, traffic signal control equipment will need to be updated to provide the necessary bus
priority features. Also, a method of bus detection will need to be chosen and implemented. At signalized
locations within the Boston Central Computer System, bus priority features are already available with the
existing equipment and no additional control equipment is necessary. A method of bus detection and
communication to the controllers will be necessary, however.
Methods of Bus Detection
There are three principal methods to enable detection of buses and initiation of traffic signal priority:
optical detection; magnetic induction; and global positioning system-based. The first method to provide
priority/preemption is via the OPTICOM system, which involves use of optical emitters on the vehicles,
optical receivers at the intersections, and priority/preemption equipment in the cabinets. This optical
system works on line of sight so the signal from the bus can be detected well upstream of most
intersections to bring early priority. Other detection systems involve a transducer on the bus and loop
detection in the roadway, which can detect the “signature” of a bus and transmit the signal via conduit to
the controller. Another system would involve installation of global positioning system (GPS) transponders
on the buses that transmit a radio signal to a receiver, which could be located at the signal control cabinet
or at a remote traffic or transit control center. The Silver Line has utilized a GPS-based that transmits
signals from the bus to MBTA Operations Center, which in turn communicates with the City of Boston
Traffic Operations Center, which can remotely control signal timings and initiate transit signal priority.
Because this system is already in place, and many MBTA buses are equipped with GPS transponders,
the GPS-based system is the most appropriate for use on the Urban Ring routes and is recommended as
part of the Build Alternative.

Traffic Controller Needs
Standard available traffic signal controllers do not have the capability of providing bus priority. It is
necessary to modify the current controller software to provide priority operation that causes the controller
to shift to a priority pattern to assist the bus to pass through the intersection. This can be accomplished
by extension of green time, skipping of non-priority phases, truncating a red signal to bring an early green
to the bus approach, and inserting additional bus phases. Following passage of the bus, compensating
time can be allocated to the non-priority phases. The priority preemption can be accomplished at an
isolated intersection or within a coordinated system. When used in a coordinated system, the coordination
can be maintained in the background while the priority call is served. When the priority sequence is
completed, the system can return to coordinated control without loss of coordination. For larger signal
systems, as in the case of Boston, a central computer can provide control of the system and provide bus
priority on a network basis through commands from the central computer to the remote intersection
controllers. Use of a central control system is recommended for each of the seven communities in the
Urban Ring corridor. This will provide the most efficient and flexible system for the traffic signal systems
in the corridor.
Intersections currently part of the Boston Traffic Operations Center (TOC) would not require new control
equipment, but will require additional detection equipment. Intersections in Boston that are currently not
connected to the central TOC would need to be upgraded to become part of the TOC or operate as an
independent system with priority at the individual controller level. Intersections with modern cabinets may
only require a new timer unit capable of handling the priority controls. Centrally controlled computer
systems are desired for locations not in the TOC. The central system will permit priority to be
implemented through a series of intersections on a system basis rather than through each individual
intersection.
During the DEIR process, the signal priority concept and potential savings and impacts was presented and
discussed with the Urban Ring Traffic and Transportation Subcommittee of the CAC and traffic officials from
the affected jurisdictions. Based on these discussions, an overall traffic signal bus priority operations
strategy has evolved which attempts to maximize travel time savings for buses while minimizing travel time
impacts for general non-priority traffic flow. This operations strategy involves using active conditional traffic
signal priority whereby real time traffic signal timing adjustments are made to expedite flow of buses subject
to conditions or limits to traffic signal timing which minimize additional delay to general traffic. In addition,
where feasible, the operations strategy calls for coordination of groups of intersections into systems to
provide progressive traffic flow through the corridor for both buses and general traffic. The general
operations strategy will be to provide traffic signal bus priority where it is possible to have minimal effects on
delay for general traffic and not to provide priority if it would cause significant negative effects on general
traffic.
Coordination Between Multiple Jurisdictions
In order to implement the proposed traffic signal bus priority operations strategy for Urban Ring Phase 2
BRT, it is necessary to provide new and upgraded traffic signal equipment at the signalized intersections
(existing and proposed) within the Urban Ring corridor. These intersections are controlled by a number of
different jurisdictions including the cities of Boston, Cambridge, Somerville, Everett, Chelsea; the Town of
Brookline; and the Department of Conservation and Recreation. It is proposed that new and upgraded
equipment at these locations be provided as part of the Urban Ring Phase 2 BRT project and that the
various jurisdictions continue to be responsible for operations and maintenance of the signal systems. An
agreement would be necessary between the MBTA and the jurisdictions to provide the desired traffic
signal bus priority operation as well as continued maintenance of equipment necessary for providing such
operation.
General Equipment Strategy
The traffic signal equipment strategy necessary to implement the proposed traffic signal operations
strategy consists of provision of new and upgraded traffic signal equipment at the project signalized
Page 149

TECHNICAL TRAFFIC REPORT
intersections. This includes control, detection, and communications equipment. Upgraded control
equipment is needed for local and system or group control to provide the real time traffic signal timing
adjustments to provide priority, coordination through a group of intersections for buses and general traffic,
and remote monitoring of priority and other traffic operations.
For bus detection, it is assumed that a similar method to that being used on the Silver Line in Boston
will be used. This consists of a GPS whereby buses are tracked via transponders on the buses
transmitting to a satellite link that in turn transmits the information to MBTA operations center. From the
operations center, information on bus location is transmitted to the intersection locations via telephone
links. In addition, upgraded vehicle detection is required at the intersections to provide information on
general traffic operations. This information will enable the control equipment to determine whether
general traffic conditions are at an acceptable level so that priority operation can be implemented.
Communications equipment is needed to interconnect all intersections into systems or groups for the
purpose of coordination of buses and general traffic through a series of intersections as well as provide
remote monitoring of bus and general traffic operations.
The following is a recommended list of new and upgraded equipment required to provide traffic signal bus
priority in the Urban Ring Phase 2 BRT corridor. This applies to all existing and proposed signalized
intersections in the corridor. For new signalized intersections or intersections within areas of roadway
reconstruction, complete upgrades including control, display, detection, and communications equipment
will be required. For most intersections, replacement of key equipment only will be required.
Control Equipment
•
Replace local intersection controllers, as needed, with new controllers capable of priority operation
and compatible with proposed system controllers. In Boston, new controllers will be compatible with
existing Boston TOC.
•
Provide new centralized control systems for overall control of groups of intersections within each
municipality. Assume DUPR intersections will be included in system for municipality in which they are
located. In Boston, all intersections will be tied to existing TOC.
•
Provide new computers in municipalities’ operation centers for remote monitoring of traffic control.
•
The central systems can provide better priority control and flexibility than the individual intersection
controller systems, but requires a major investment in control equipment and cooperation between
the local jurisdictions.
Display Equipment
•
Provide new vehicle signal head displays where necessary for special bus only phases for bus only
movements and queue jumps.
Detection Equipment
•
Provide transponders on buses for GPS for tracking of bus locations with satellite link to MBTA
operations headquarters. Provide telephone link for transmission of information from MBTA
operations center to street intersection controllers.
•
Provide new vehicle detection at local intersections for system monitoring of traffic demands at
intersections to be used in determination of application of signal priority.

Communications Equipment
•
Provide new communications links between all local intersection controllers and street master system
controller within proposed municipal systems for coordination of bus and traffic movements, remote
monitoring, and central control.
•
Provide new communications links between new central system controllers and street master
controllers within each municipal system. In Boston, all intersections will be tied into existing TOC.
•
Provide communications linkage between MBTA operations center and new central system
controllers, street master, or local controllers for communication of bus location information.

Transit Signal Priority Research
This section summarizes research conducted in August and September 2008 regarding current practice using
transit signal priority (TSP) in the United States and Canada. The research shows that TSP is being used in
several metropolitan areas to improve travel times for public transportation systems. Three public
transportation systems in particular, LYMMO BRT Service in Orlando, FL; Metro Rapid Bus in Los Angeles,
CA; and North Las Vegas MAX BRT Service in Las Vegas, NV use queue jumper lanes with transit-only signal
heads as part of their systems. A fourth example of transit signals in use exists in Toronto, Canada.
Examples of Transit Signal Priority with General Traffic
LYMMO BRT service, Orlando, FL - provided by the Central Florida Regional Transportation Authority
(known as LYNX), operates in downtown Orlando. The following is from the “LYMMO Bus Rapid Transit
Evaluation” Final Report July 2003.
Page 155
November 2008
URBAN RING PHASE 2
TECHNICAL TRAFFIC REPORT
Exclusive Bus Traffic Signal Phasing (p. 15)
At 11 intersections, approaching buses actuate exclusive bus phases. Windows for bus-only phases (about 10
seconds) are available only at the end of a concurrent auto phase or the beginning of an opposing phase.
Because the LYMMO operates in places and directions contrary to other vehicular traffic, all bus movements
at intersections are controlled by special bus signals. To prevent confusion, the bus-only signal heads are
mounted directly over the bus-only lanes and use illuminated lunar white bars on a three-aspect display unit to
signify Stop, Prepare To Go, and Go. The signals are loop actuated so that non-LYMMO buses using the busonly lanes will get a signal. Basically, when a LYMMO vehicle approaches an intersection, a loop detector in
the bus-only lane triggers the intersection to allow the vehicle to proceed either in its own signal phase (e.g.
when making turns not otherwise permitted) or at the same time as other vehicular traffic is released when no
conflicting traffic movements are permitted. All time for activation of a bus-only phase is taken from the time
allotted to the minor cross-street phases so progression on the major street is not disrupted.
Figure I-2 shows the special Lymmo transit signal head on the left adjacent to a standard signal head on the
right.
Figure I-2
Lymmo Transit Signal Head, Orlando, FL
Metro Rapid Bus, Los Angeles, CA – The following is from “Metro Rapid Demonstration Program Evaluation
Report” on the FTA website:
ATSAC and TPM System Operation
Each signalized intersection in the project area is equipped with loop detectors that serve as Automatic
Vehicle Identification (AVI) sensors. These sensors embedded in the pavement receive a radio-frequency
code from a small transponder installed on the underside of a vehicle. Buses equipped with unique
transponders will be detected when traveling over the loop detectors. These loops are connected to a sensor
unit within the traffic signal controller at each intersection, which transmits the bus identification number to the
Transit Priority Manager (TPM) computer in the City’s Automated Traffic Surveillance and Control (ATSAC)
Center at City Hall East for tracking and schedule comparison.
Page 156
November 2008
URBAN RING PHASE 2
TECHNICAL TRAFFIC REPORT
Once the bus identification and location are received by the TPM, the computer makes a determination of the
need for traffic signal priority. If the bus is early or ahead of the scheduled headway, no traffic signal priority
treatment is provided. However, if the bus is late or beyond the scheduled headway, then the downstream
traffic signal controller will provide signal priority to help the bus catch up with the scheduled headway. In
addition, real-time data links from the Los Angeles County Metropolitan Transportation Authority (MTA)
dispatch center to the ATSAC center is used to obtain the daily bus assignment for schedule comparison.
Individual Intersection Operation
Traffic signal control at each intersection is provided by Model 2070 controllers that are equipped with a stateof-the-art software program developed by the City of Los Angeles specifically for this project. Once the Model
2070 traffic signal controller receives a request from the Transit Priority Manager, it implements one of the
following four types of traffic signal priority actions depending upon the point in time when the signal controller
receives the commands, relative to the background cycle:
Types of Priority
•
Early Green priority is granted when a bus is approaching a red signal. The red signal is shortened to
provide a green signal sooner than normal.
•
Green Extend priority is granted when a bus is approaching a green signal that is about to change. The
green signal is extended until the bus passes through the intersection.
•
Free Hold priority is used to hold a signal green until the bus passes through the intersection during
non-coordinated (free) operation.
•
Phase Call brings up a selected transit phase that may not normally be activated. This option is typically
used for queue jumper operation, or a priority left turn phase.
North Las Vegas MAX, Las Vegas, NV - The following is from “North Las Vegas MAX BRT Project 2006
Evaluation”, page 28, on FTA website:
Queue Jumper
The single “queue jumper” in the system is located at Jerry’s Nugget southbound station where Las Vegas
Boulevard North crosses Tonapah. A request to “jump queue” is triggered when the induction loops in the
right-turn only lane sense a vehicle and the vehicle transmits an Opticom infrared signal. A request, therefore,
will only be triggered when a vehicle is waiting at a red light. Upon receiving the request, the traffic signal
controller displays a special white bar signal, indicating a bus-only green. This signal lets the driver continue
straight from the right-turn only lane, before other traffic is released. The Jerry’s Nugget southbound station is
an excellent location for the technology because the road drops from three to two lanes, creating the potential
to delay a transit vehicle waiting to merge out of a station.
Minimal problems have been experienced with the technical functions of the queue jumper system; in some
cases members of the public who do not understand the system have called the police, reporting a vehicle
running a red light.
Responses show that 95% of bus operators surveyed believe that it helps to speed service.
Figures I-3 and I-4 show examples of transit signals used in North Las Vegas MAX.

TECHNICAL TRAFFIC REPORT
Saint Claire Corridor, Toronto, Canada
In downtown Toronto, Canada, Toronto Transit Commission’s (TTC’s) trolleys and buses employ transit signal
priority whereby signals for transit are located adjacent to signals for general traffic, as shown in Figure I-5
below. There are signs posted above and below the transit signal to distinguish it from the general traffic
signal. In addition, the transit signal housing is black in contrast to the yellow signal housing for the general
traffic signal.
Figure I-5

In summary, the examples provided above show that bus signal priority is being used successfully along with
general traffic signalization in both the U.S. and Canada.

Intersection Capacity Analysis Tables
A model of the study area roadway network was developed using the SYNCHRO traffic analysis program to
evaluate study intersections along the Urban Ring BRT Phase 2 alignments. SYNCHRO models developed by
the cities of Boston and Cambridge were incorporated in into the Urban Ring model. Due to the length of the
study corridor (approximately 25 miles), the model network was separated into segments around the Urban
Ring Project Corridor. Tables J-1 through J-13 provide morning and afternoon Level of Service (LOS) analysis

URBAN RING PHASE 2
TECHNICAL TRAFFIC REPORT
K.
Surface Routing Analyses in the Longwood Medical and Academic
Area
The LPA alignment includes a tunnel through the Longwood Medical and Academic Area (LMA) and Fenway.
It is understood that while the tunnel will provide superior travel time and reliability service, it will take several
years to fund, design, and construct. Therefore, interim surface alignment options were evaluated that would
provide travel time and reliability advantages for Urban Ring buses until the tunnel is completed.
The interim surface options include busways, bus lanes, queue-jump lanes and bus signal priority at critical
locations in the LMA and Fenway. Evaluation results (see the memorandum provided at the end of this
section) indicate that these measures would reduce delay and improve travel times for buses in both existing
and future conditions. However, there are challenges and trade-offs involved with most of the interim
improvement measures evaluated including impacts to general traffic, pedestrian crossing times, turning radii,
and land acquisition. The project team has coordinated with the City of Boston, stakeholders and MASCO and
has addressed most of the issues and concerns raised. The memorandum provided at the end of this section
represents the most current analysis by the project team.
An interim surface plan in the LMA and Fenway area has not been finalized. An ongoing process of
coordination with the City of Boston and stakeholders will continue.

Longwood Medical and Academic Area (LMA) – Interim Surface Option
Distribution:
This memorandum has been prepared to summarize the advantages of the Urban Ring interim surface
improvements proposed in the Longwood Medical and Academic Area (LMA). The surface improvements
within the LMA typically include exclusive bus lanes or “queue jump” lanes, and a priority signal phase for the
bus movements. Figure 1 shows the interim surface routes between Yawkey Station and Ruggles Station
through the LMA. Figures 2 and 3 show the potential interim surface improvements in the LMA and along
Ruggles Street, respectively.
Tables 1 and 2 summarize anticipated traffic operating conditions in the year 2030 at several key intersections
along the interim surface route in the LMA. At each intersection, the delays and queue lengths for the bus
movements are shown with and without the proposed improvements. Additionally, the overall intersection
delay for general traffic is also included in the tables.
