Road Safety Audit – Middlesex Turnpike between Wheeler Road (East) and I-95 Southbound Ramps
Prepared by TEC, Inc.
Background
The Town of Burlington is currently planning roadway improvements along the Middlesex Turnpike
corridor in an effort to address existing safety concerns and to increase capacity within the vicinity of the
planned 63 South Avenue – Burlington Research Center development project by The Gutierrez Company.
The Town was recently awarded a MassWorks grant from the Executive Office of Housing and Economic
Development (EOHED) for the construction of these roadway improvements. The addition of new
vehicle trips to Middlesex Turnpike, which is the urban minor arterial roadway adjacent to the project
site, has stimulated roadway improvements and a corresponding Functional Design Report (FDR) to be
prepared by Transportation Engineering and Construction, Inc. (TEC, Inc.) of Lawrence, Massachusetts.
The project includes work along two different sections of Middlesex Turnpike, one in the Town of
Burlington’s jurisdiction at Second Avenue / Burlington Mall Road and the other within Massachusetts
Department of Transportation (MassDOT) jurisdiction at the I-95 Ramp terminals and Wheeler Road.
This Road Safety Audit (RSA) applies only to the intersections within MassDOT’s jurisdiction.
The purpose of an RSA is to observe, identify, and report all safety issues and identify future
opportunities for safety improvements for all roadway users. The MassDOT guidelines require an
RSA to be conducted where HSIP-eligible crash clusters are present within the scope of a 25% Design
and FDR. An intersection is defined as HSIP-eligible if the intersection is within the top 5% of clusters in
its respective Regional Planning Commission’s (RPC) boundaries. Along the Middlesex Turnpike
corridor, three HSIP-eligible intersection clusters, which were identified on MassDOT’s online database
and established using crash data from 2008-2010, are present within the scope of the FDR. Therefore, an
RSA was conducted along Middlesex Turnpike at and between the following intersections:



Wheeler Road (East) Interstate 95 (also signed as US Route 3 and Route 128) Northbound Ramps / Wheeler Road (West)
Interstate 95 (also signed as US Route 3 and Route 128) Southbound Ramps An RSA, as defined by the Federal Highway Administration (FHWA), is the formal safety
performance examination of an existing or future road or intersection by an independent,
multidisciplinary team. This RSA was conducted during the Preliminary Design (pre-25% Design) stage
of intersection and corridor improvements along the Middlesex Turnpike in Burlington, Massachusetts in
order to incorporate safety-related design features early in the design process. These roadway
improvements are in conjunction with the construction of a private development located along South
Avenue in the Town of Burlington. Elements of the RSA will be considered for incorporation into the
roadway improvement Project as the design is advanced through the MassDOT design development
process in order to obtain a construction Highway Access Permit from District 4.
Project Data
Transportation Engineering and Construction, Inc. (TEC) of Lawrence, Massachusetts is the prime safety
investigation consultant in an RSA for the Middlesex Turnpike from Wheeler Road (East) to the Interstate
95 Southbound Ramps in Burlington, Massachusetts. The RSA was conducted on Tuesday November 27,
Page 1

Prepared by TEC, Inc.
2012 at 10:00 AM, with the pre- and post-audit meetings held at 63 South Avenue in Burlington,
Massachusetts. A copy of the RSA agenda can be found in Appendix A. TEC conducted various other
site visits to the audit area as part of its FDR and pre-25% Design work.
As presented in Table 1, the audit team consisted of a cross-section of state, regional, and local
engineering, planning, enforcement, maintenance and emergency response professionals and was
assembled in conjunction with input from the MassDOT’ Traffic Safety Management Unit. Contact
information for all team members is provided in Appendix B.

Audit participants were provided with materials to review prior to the audit meeting. The materials
included a summary of traffic volume data (daily and peak hour) and collision diagrams that summarized
the type and severity of collisions at the study area intersections. Participants were encouraged to visit
the site prior to the audit and were urged to consider elements on MassDOT’s Safety Review Prompt
List.
On the day of the audit, a pre-audit meeting was held at the 63 South Avenue in Burlington to discuss
the project’s background, the audit process, review the distributed materials, and discuss the some of the
issues that Team members had observed individually. The audit site walk consisted of field observations
at the audit intersections and roadway locations. Handwritten notes and photographs documented the
observations made by audit team members during the site walk. Following the audit site walk, a postaudit meeting was held at 63 South Avenue in Burlington where the Team confirmed the observations
made in the field and offered solutions to remedy the safety deficiencies noted in the Site Walk and PreAudit meeting.

Project Location and Description
The Road Safety Audit intersection locations were as follows:



Middlesex Turnpike / Wheeler Road (East) Middlesex Turnpike / Wheeler Road (West) / Interstate 95 (Route 128 / US Route 3) Northbound Ramps Middlesex Turnpike / Interstate 95 (Route 128 / US Route 3) Southbound Ramps Middlesex Turnpike
Middlesex Turnpike generally runs in the north-south direction passing through Burlington from Billerica
/ Bedford to the north and Lexington / Arlington to the south. The roadway parallels the Northwest
Expressway (US Route 3) to the north of Interstate 95 at a typical offset of approximately one-half mile.
The Middlesex Turnpike is classified as an urban minor arterial. It is under the jurisdiction of the Town
of Burlington, except for a short segment at the Interstate 95 (Route 128 / US 3) interchange and bounded
by the Southbound Ramps to the north and Northbound ramps to the south for which it is under the
jurisdiction of MassDOT.
Between Wheeler Road and Burlington Mall Road / Second Avenue, Middlesex Turnpike is a four- to
six-lane, median divided roadway with multiple turn-lanes at the various side street intersections. A
sidewalk is provided on the westerly edge of the Middlesex Turnpike from the southern edge of the
Barnes and Noble property (opposite the Interstate 95 Southbound Ramps) north to Network Drive. Land
uses along the corridor include office, commercial, industrial, and retail uses.
The posted speed limit along Middlesex Turnpike is 35 miles per hour (mph) in both the northbound and
southbound directions. Speed regulations maintained by MassDOT Highway Division establish a 35 mph
speed limit for Middlesex Turnpike (known as Middlesex Street in the regulations). Historic speed
regulations are included in Appendix D.
Middlesex Turnpike / Wheeler Road (East)
Wheeler Road (East) intersects the Middlesex Turnpike to
form a three-way, fully-actuated signalized intersection.
The intersection is under the jurisdiction of the Town of
Burlington. The Wheeler Road (East) westbound approach
consists of an exclusive left-turn lane and an exclusive
right-turn lane. Directional flow along Wheeler Road
(East) is separated by a marked centerline. The Middlesex
Turnpike northbound approach consists of a through lane
and a shared through / right-turn lane. A two-way left-turn
lane (TWLTL), which accommodates turning movement
within the Middlesex Turnpike to the south, terminates at
this intersection. The Middlesex Turnpike southbound
approach consists of an exclusive left-turn lane and two

Road Safety Audit – Middlesex Turnpike between Wheeler Road (East) and I-95 Southbound Ramps
Prepared by TEC, Inc.
Audit Observations
Prior to the RSA site walk, a pre-audit meeting was held at 63 South Avenue in Burlington, MA. This
pre-audit meeting included brief introductions, an overview of the project and RSA process, and a
summary of volume, speed, and safety characteristics along the segment of the Middlesex Turnpike.
Audit participants then conducted a site walk as a group to observe the roadway segment and
intersections. Each participant was advised to offer their concerns and comments related to safety
deficiencies along the roadway segment and study area intersections.
Based on these field observations and discussions, the RSA team determined that the Middlesex Turnpike
corridor has the following general issues that negatively impact safety:











Conflicting Lane Configuration Signage,
Faded and Missing Pavement Markings,
Traffic Congestion / Long Vehicle Queues,
Excessive Red-Light Running,
Limited Lighting,
Limited Pedestrian Accommodations,
Blocked From View or Missing Street Signage,
Inadequate or damaged signal equipment,
Blocked Drainage Structures,
Fair to Poor Pavement Conditions, and
Lack or Misplaced Freeway Signage
The following sections describe in more detail the safety issues determined during the RSA. Several of
these require further evaluation and design work to develop appropriate safety enhancements. More
specific safety challenges located at specific audit area intersections are also included.
General Study Area Observations
The RSA team noted several general safety issues throughout the Middlesex Turnpike corridor. A
summary of those general safety concerns throughout the study area are as follows:
 Conflicting Lane Configuration Signage – The lane
configuration signage (R3-8 series) along the
Middlesex Turnpike southbound between the
Interstate 95 Southbound and Northbound Ramps
are conflicting. Over the 250 foot roadway
segment, three sets of lane configuration signage
are visible to the roadway user. The first visible
sign (L,L,T,TR), shown at the left of the image, is
the correct lane configuration but is 120 feet in
advance of the signed roadway configuration
downstream. The second visible sign (L,L,TR),
shown in the center of the image, is incorrect. The
Lane Configuration Signage along
Middlesex Turnpike Southbound
Page 6
Road Safety Audit – Middlesex Turnpike between Wheeler Road (East) and I-95 Southbound Ramps
Prepared by TEC, Inc.
third visible sign (L,L), on the far right of the image in the distance, is along the dual left-turn
lane approaching the I-95 Northbound Ramps and only shows the dual left-turn lanes in its
configuration which is incorrect for the entire four-lane approach.
These conflicting lane configuration signage causes confusion amongst drivers attempting to
weave from right to left in order to turn left onto the I-95 Northbound On-ramp. The second lane
configuration sign (L,L,TR) conveys to unfamiliar drivers that the second far right lane is a turn
lane causing quick weaves and lane changes within the intersection as the driver becomes aware
of their lane choice error.
 Pavement Markings – Pavement markings are
severely faded along several portions of the audit
area and not visible along the Middlesex Turnpike
directly under the Interstate 95 overpass. The lack
of pavement markings decreases the visibility of
defined lane use in a section of roadway that
experiences an increased amount of weaving and
lane change movements. The Middlesex Turnpike
northbound between the Interstate 95 Northbound
and Southbound Ramps is typically striped to
accommodate three travel lanes. At the current
Pavement Markings along Middlesex
time, the pavement markings are faded to a point
Turnpike. where it seems only two travel lanes exist. Several
pavement arrows delineating turning movements are also faded at the three intersections.
 Traffic Congestion / Queues – Due to the numerous commercial, retail, and office uses along the
Middlesex Turnpike, traffic volumes in the area generally increase during the weekday peak
periods and during Saturday peak periods. The traffic volumes increase significantly during the
month of December given the corridor’s location in close proximity to the Burlington Mall.
These additional traffic volumes result in increased traffic congestion along the Middlesex
Turnpike, the Interstate 95 Ramps, and the side streets such as Wheeler Road. With the close
proximity of the Interstate 95 Northbound Ramps and Wheeler Road (East), traffic often queues
from one intersection into the upstream intersection. These queues can cause blocked
intersections as part of a “grid-lock” condition. A representative of the Burlington Police
Department noted that police are typically assigned to this roadway segment to deter intersection
blockage, however; intersection blocking still occurs regularly during peak holiday shopping
periods.
A representative of the Burlington Fire Department researched and noted that it takes
approximately 3.5 minutes for a fire response vehicle to travel from Station #2 (Terrace Hall
Avenue @ Middlesex Turnpike) to the mall and it takes approximately 6.5 minutes to travel from
Station #2 to Middlesex Commons. This equates to 3 extra minutes of travel time for an
additional 4,000 feet of travel.

Prepared by TEC, Inc.
 Red-Light Running – A representative of the Burlington Police Department noted that red-light
running at these intersections is prevalent and is usually caused by user frustration with
congestion during peak periods. The Police representative also noted the difficulty of
enforcement of red-light running and other such roadway violations as there is no safe location to
pull-over vehicles along the Middlesex Turnpike.
 Lighting – Although ambient light and street lighting is present along the Middlesex Turnpike,
there is no under-decking lighting along the Middlesex Turnpike under the Interstate 95 overpass.
According to MassDOT, lighting on the under-decking has existed in the past and has since been
removed and not replaced. In addition, highway lighting within the cloverleaf interchange is
present, but often not functioning properly. At the time of the RSA, all cloverleaf lighting was
functioning and operational.
 Pedestrian Accommodations – A sidewalk is
currently constructed along the westerly side of the
Middlesex Turnpike from the Barnes and Noble
property and continuing northbound to Network
Drive. South of this location, a sidewalk is
intermittently constructed along the westerly side of
the roadway and under the Interstate 95 underpass
only. There are no current pedestrian crossing
locations across the Middlesex Turnpike in the
vicinity of the Audit area. A Town representative
noted that various office and commercial
Break in Sidewalk along Westerly Side of Middlesex Turnpike
employees will cross Middlesex Turnpike near
Wheeler Road (East) to access the Dunkin Donuts on the southeast corner of the intersection. In
addition to a lack of sidewalk infrastructure between the intersections, no pedestrian signal
equipment is present at the intersections and no pedestrian phasing is included in the signal
timing plan.
 Blocked or Missing Street Signage – An RSA member noted that the visibility of the Wheeler
Road and Middlesex Turnpike street sign plaques is limited due to the sign posts position behind
a utility pole offset from the edge of roadway. In addition, there is no “Middlesex Turnpike” sign
plaque on the Wheeler Road (West) sign post opposite the Interstate 95 northbound ramps.
Finally, street name plaques are mounted at different heights at each different intersection in the
Audit area and along the Middlesex Turnpike corridor.
 Signal Equipment – There are several signal equipment deficiencies which are listed below:
o All of the signal housings at all three intersections lack retro-reflective back-plates, which
would clearly define individual signal housing to the roadway user.
o The left-turn signal housing on the Wheeler Road (East) westbound approach is not
clearly centered on the approach lane.
o All three signals are equipped with emergency pre-emption. However, upon observation,
the pre-emption at the Middlesex Turnpike / Interstate 95 Northbound Ramps / Wheeler
Page 8
Road Safety Audit – Middlesex Turnpike between Wheeler Road (East) and I-95 Southbound Ramps
Prepared by TEC, Inc.
Road (West) intersection did not activate as an ambulance traversed through. A
MassDOT technician corrected the programming immediately following the audit.
o The Middlesex Turnpike northbound right-hand through lane loop detector at the
Interstate 95 Northbound Ramps is currently faulting. The line was recently cut as part of
trenching within the roadway and was not replaced by the Town of Burlington.
 Pavement Condition – It was noted that the pavement is in fair condition along the Middlesex
Turnpike corridor. However there are scattered pot-hole locations, especially near several
drainage structures. In addition, there is a large quantity of cracking on the pavement which has
been repeatedly filled-in by the Town of Burlington. There is significant truck traffic due to the
number of nearby retail and commercial businesses, which causes increased wear on pavement
conditions.
 Drainage Structures – Several RSA members noted that a few drainage structures along the
Middlesex Turnpike were significantly blocked by debris and built-up sediments.
Obstructed drainage structures can cause severe water ponding
and minor flooding on roadway segments with
raised curbing and level or deflated roadway
surfaces. With excessive vehicle speeds observed during off-peak hours along the Middlesex Turnpike corridor, this ponding may become a substantial safety concern. All drainage structures along the Middlesex Turnpike corridor should be Obstructed Catch Basin along Middlesex
cleared of all potential obstructions by their
Turnpike near Wheeler Road (West) respective maintenance crews.  Freeway Signage – On the southbound approach of Middlesex Turnpike, there is a lack of clear
signage that defines both the southbound and northbound ramps of Interstate 95. Green guide
signs were recently installed and are located within the ramp medians. These signs give vague
direction to the roadway user. Although the signs are visible from a distance, no signs decipher
lane information to access the I-95 Ramps. Drivers tend to focus on following the large
horizontal arrow pointing to the ramps and disregard the lane configuration signage along the
roadway causing unorganized weaving.
No clearly defined “I-95 Shield” is visible along the approach. A “Route 128 South” sign is
visible, but is located on the right-side of the roadway away from the southbound left-turn lane
onto the ramp. This may cause excessive weaving and lane changes as a result of roadway user
making delayed route choice decisions on the approach.
Middlesex Turnpike / Wheeler Road (East)
The intersection of Middlesex Turnpike / Wheeler Road (East) is considered HSIP-eligible. Collision
data for this intersection was provided by the Town of Burlington Police Department for the period of
January 2009 to December 2011 and supplemented by MassDOT for the period of January 2008 to
December 2010. The data shows a total of 46 reported collisions in the area of the intersection during the
four-year study period. The crash rate for this intersection is slightly higher than the statewide and
Page 9
Road Safety Audit – Middlesex Turnpike between Wheeler Road (East) and I-95 Southbound Ramps
Prepared by TEC, Inc.
district-wide averages for unsignalized intersections with 0.84 crashes per million entering
vehicles (MEV). A summary of the intersection audit is described below.
There were 16 angle-type collisions (35%) at this intersection over the four-year study period. Of the
locatable angled collisions, approximately half (6 of 11) involved a vehicle exiting Wheeler Road (East).
There were also 7 rear-end crashes (15%) at this intersection over the four-year study period. Of the
locatable rear-end collisions, a majority (4 of 6) occurred on the Middlesex Turnpike northbound
approach. Although most crash data did not specify a detailed vehicle action prior to crash, five (5)
collisions at this intersection involved vehicles attempting to enter travel lanes or vehicles changing lanes.
The RSA team noted several general safety issues specifically at the intersection of Middlesex Turnpike /
Wheeler Road (East). A summary of those general safety concerns at the intersection are as follows:
 Southbound Left-Turn Lane Definition – RSA team members noted that the left-turn from
Middlesex Turnpike southbound onto Wheeler Road East is not clearly defined for the
receiving area for vehicles exiting the Interstate 95 Northbound Off-ramps and Middlesex
Turnpike southbound vehicles. There is no clear transition into the southbound exclusive
left-turn lane, and vehicles exiting the ramps and Middlesex Turnpike might
unexpectedly find themselves in an exclusive left-turn lane while intending to proceed
through.. This may cause drivers that are unfamiliar with the lane configuration to weave
in and out of the left-turn lane approaching Wheeler Road (East) from the north.
 Signal Housing Location - As stated previously, it was noted that the left-turn signal
housing on the Wheeler Road westbound approach is not clearly centered on the
approach lane and should be appropriately moved within a proper cone of vision.
 Intersection Blockage – As stated previously, with the close proximity between the
Interstate 95 Northbound Ramps and Wheeler Road (East), traffic tends to queue from
one intersection into the upstream intersection. This queue often causes blocked
intersections disallowing side street traffic from exiting. A representative of the
Burlington Police Department noted that police are typically assigned to this roadway
segment to deter intersection blockage, however; intersection blocking still occurs
regularly.
 Pedestrian Accommodations – Pedestrians are often seen crossing the Middlesex
Turnpike at this location in order to access the Dunkin Donuts on the southeast corner of
the intersection. However, no defined crossing opportunities exist at this intersection and
there are currently no additional sidewalks except the sidewalk along the Dunkin Donuts
frontage.
 Blocked Street Signage - An RSA member noted that the visibility of the Wheeler Road
and Middlesex Turnpike street sign plaques are limited due to the sign posts position
behind a utility pole offset from the edge of roadway. This had the potential to cause
confusion with roadway users, especially as Wheeler Road in this location is separated
east and west by one block along Middlesex Turnpike.

Middlesex Turnpike / Wheeler Road (West) / Interstate 95 (Route 128 / US 3) Northbound Ramps
The intersection of Middlesex Turnpike / Wheeler Road (West) / Interstate 95 (Route 128 / US 3)
Northbound Ramps is specifically not considered HSIP-eligible. However, the Middlesex Turnpike
surface ramp intersection is part of the larger Interstate 95/ US Route 3 interchange which as a whole has
been classified as HSIP-eligible. Collision data for this intersection was provided by MassDOT for the
period of January 2008 to December 2010 and supplemented by the Town of Burlington Police
Department for the period of January 2009 to December 2011. The data shows a total of 39 reported
collisions in the area of the intersection during the four-year study period. The crash rate for this
intersection is significantly lower than the statewide and district-wide averages for unsignalized
intersections with 0.53 crashes per million entering vehicles (MEV). A summary of the
intersection audit is described below.
There were 16 rear-end collisions (41%) at this intersection over the four-year study period. Of the
locatable rear-end collisions; a majority (6 of 11) involved a vehicle travelling north along Middlesex
Turnpike. Two (2) of these rear-end collisions occurred within the Interstate 95 Northbound Ramp rightturn channelized lane resulting from vehicles stopping at the end of the ramp. There were also 4 angletype collisions (9%) at this intersection over the four-year study period. Of the locatable rear-end
collisions, a majority (3 of 4) occurred on the Middlesex Turnpike northbound approach resulting from
vehicles attempting to turn-left into Wheeler Road (West) and may be a result of left-turning vehicles
unable to see oncoming traffic.
Not all of the MassDOT Crash Data clearly decipher between collisions that occurred at the surface
intersections of the Interstate 95 (Route 128 / US 3) Northbound Ramps with the Middlesex Turnpike
versus collisions that may have occurred along Middlesex Turnpike or Interstate 95 near the interchange.
In addition, the data does not clearly indicate whether the collisions occurred at the northbound or
southbound ramps to/from the Middlesex Turnpike. After review of individual crash reports, a large
number of crashes reported at this junction were found not to be at the surface intersections. To remain
conservative, those crashes whose location could not be clearly deciphered were included within the
collision data. As a result, the crash information may not be representative of the safety characteristics of
the northbound surface ramp intersection with the Middlesex Turnpike.
The RSA team noted several general safety issues specifically at the intersection of Middlesex Turnpike /
Wheeler Road (West) / Interstate 95 (Route 128 / US Route 3) Northbound Ramps. A summary of those
general safety concerns at the intersection are as follows:
 Lane Usage / Traffic Control on Northbound Ramps – Currently, a YIELD sign is present at the
terminus of the I-95 Northbound off-ramp right-turn channel lane. This YIELD sign is currently
not warranted as the turn-lane enters its own dedicated lane along the Middlesex Turnpike which
is not clearly defined due to lack of pavement markings. Vehicles tend to stop, then progress, and
stop again while attempting to enter the Middlesex Turnpike traffic flow. A representative from
the Burlington Police Department noted that this causes frequent rear-end crashes and “near
misses” within the channelized right-turn lane. As noted above, two crashes were identified as a
result of this movement.
 Opposing Lane Alignment - Vehicles exiting the I-95 northbound ramps do not have a direct
track to access the opposing Wheeler Road (West) receiving lane. Concurrently, vehicles exiting
Wheeler Road (West) attempting to access the I-95 northbound on-ramp also must divert and
Page 11
Road Safety Audit – Middlesex Turnpike between Wheeler Road (East) and I-95 Southbound Ramps
Prepared by TEC, Inc.
correct a thru movement across the intersection. This is especially difficult for unfamiliar roadway
users attempting to cross Middlesex Turnpike. Future potential exists to reset the alignment of both the ramps and Wheeler Road (West); however, this
would include major right-of-way impacts.  Northbound Left-turns – Northbound left-turn movements at the signalized intersection are considered unsafe to potential roadway users as the intersection does not have a protected left-turn lane View of Alignment of Wheeler Road (West) which operates under an exclusive phase.
verses the I-95 Northbound Ramps
(from Wheeler Road)
Furthermore, the northbound left-turn from
Middlesex Turnpike into Wheeler Road (West) is unsafe as turning vehicles cannot clearly see
opposing southbound through traffic as they are blocked by queued traffic in the dual southbound
left-turn lanes. A “LEFT-TURN YIELD ON GREEN BALL” sign (R10-12) was requested by
the Burlington Police Department and installed and has decreased the number of angled crashes
as noted by a Burlington Police Department representative.
 Loop Detection - The Middlesex Turnpike northbound right-hand through lane loop detector at
the Interstate 95 Northbound Ramps is currently faulting. A representative of the Town of
Burlington noted that the line was recently cut as part of trenching within the roadway and was
not replaced by the Town of Burlington.
Middlesex Turnpike / Interstate 95 (Route 128 / US 3) Southbound Ramps
The intersection of Middlesex Turnpike / Interstate 95 (Route 128 / US 3) Southbound Ramps is
specifically not considered HSIP-eligible. However, the Middlesex Turnpike surface ramp intersection is
part of the larger Interstate 95/ US Route 3 interchange which as a whole has been classified as HSIPeligible. Collision data for this intersection was provided by MassDOT for the period of January 2008 to
December 2010 and supplemented by the Town of Burlington Police Department for the period of
January 2009 to December 2011. The data shows a total of 45 reported collisions in the area of the
intersection during the four-year study period. The crash rate for this signalized intersection is
significantly lower than the statewide and district-wide averages for unsignalized intersections
with 0.59 crashes per million entering vehicles (MEV).
There were 10 angle-type collisions (22%) at this intersection over the four-year study period. There
were also 12 rear-end crashes (27%) at this intersection over the four-year study period. Of the locatable
rear-end collisions, a majority (4 of 7) occurred on the Middlesex Turnpike southbound approach. Four
(4) collisions were classified as sideswipe collisions. Although most crash data did not specify a detailed
vehicle action prior to crash, five (5) collisions at this intersection involved vehicles attempting to enter
travel lanes or vehicles changing lanes.
Not all of the MassDOT Crash Data clearly decipher between collisions that occurred at the surface
intersections of the Interstate 95 (Route 128 / US 3) Southbound Ramps with the Middlesex Turnpike
versus collisions that may have occurred along Middlesex Turnpike or Interstate 95 near the interchange.
In addition, the data does not clearly indicate whether the collisions occurred at the northbound or
Page 12
Road Safety Audit – Middlesex Turnpike between Wheeler Road (East) and I-95 Southbound Ramps
Prepared by TEC, Inc.
southbound ramps to/from the Middlesex Turnpike. After review of individual crash reports, a large
number of crashes reported at this junction were found not to be at the surface intersections. To remain
conservative, those crashes whose location could not be clearly deciphered were included within the
collision data. As a result, the crash information may not be representative of the safety characteristics of
the southbound surface ramp intersection with the Middlesex Turnpike.
The RSA team noted several general safety issues specifically at the intersection of Middlesex Turnpike /
Interstate 95 (Route 128 / US Route 3) Southbound Ramps. A summary of those general safety concerns
at the intersection are as follows:
 Red-Light Running – A representative of the Burlington Police Department noted that red-light
running at the intersection of Middlesex Turnpike / Interstate 95 Southbound Ramps is prevalent
and is usually caused by user frustration with congestion during peak periods. The Police
representative also noted the difficulty of enforcement of red-light running and other such
roadway violations in the area as there is no safe location to pull-over vehicles along the
Middlesex Turnpike.
 Lack of Curb Reveal – There is little to no curb reveal
along the Middlesex Turnpike median at the intersection with the Interstate 95 Southbound Ramps.
Vehicles turning left while exiting the off-ramp and vehicles making northbound U-turns tend to cross over
the median during the turning movement.  U-turns – U-Turns are prevalent along the entire
Middlesex Turnpike corridor to the north and south of
the audit area. U-turns were notably occurring at the
Middlesex Turnpike’s intersection with the Interstate
95 Southbound Ramps on the northbound approach Raised Concrete Median along Middlesex
Turnpike.
before the destruction of the former Burlington Dodge
Dealership site which was between Interstate 95 and the Barnes and Noble property. With the
development of Middlesex Marketplace, which will be constructed on the former Burlington
Dodge site, U-turns may return to this location if the site’s driveway approach is not aligned with
the signalized intersection.
Crash data summaries and a collision diagram are included in Appendix C.

Summary of Road Safety Audit
Based on the observations and discussions, the RSA team identified safety issues along the Middlesex
Turnpike corridor between Wheeler Road (East) and the Interstate 95 Southbound Ramps. Further
evaluation and design work may be necessary to develop safety enhancements to the roadway and
intersections. The safety issues are summarized in Table 2.
For each safety issue, the RSA team has described the potential safety enhancement, its potential safety
payoff, the estimated time frame for completion, the estimated construction cost, and the jurisdictional
agency. Design plans are in progress for the Audit’s location area and the scope of the roadway
improvements shall be made consistent with the MEPA permitting review/approval process and all
necessary access permits for the Burlington Research Center. The approved project limits of the
improvements, to be funded by the MassWorks grant, begin just south of the I-95 southbound ramps and
extend to the southbound approach to the intersection of the Middlesex Turnpike with Wheeler Road
(East). The current scope will continue to be refined through coordination between the Project Team, the
Town of Burlington, and MassDOT. As design plans are in the pre-25% Design phase, some potential
safety enhancements will be incorporated into the design for the 25% Design Submission.
The summary of potential safety enhancements are summarized in Table 3 and include a column
identifying the improvements within the current project design. As the design plans progress, the safety
enhancements, identified by the RSA, will be incorporated into the design to the extent feasible based
upon agreements between the Project Team, the Town of Burlington, and MassDOT.
The time frame is categorized as short-term (<1 year), mid-term (1 to 3 years), or long-term (>3 years).
The costs are categorized as low (<$10,000), medium ($10,001 to $50,000), or high (>$50,001).
