Background
The intersection of Route 27 (Crescent Street)/Quincy Street/Massasoit Boulevard in Brockton,
Massachusetts, was listed in the Top 5% of High Crash Locations within the Old Colony Planning
Commission (OCPC) in 2009. The Massachusetts Department of Transportation (MassDOT) has
determined that Highway Safety Improvement Program (HSIP) funding would be allowed for
reconstruction of the intersection if a Road Safety Audit (RSA) were conducted and a proposed design
incorporated the safety improvements identified in the RSA. The intersection is currently identified as a
proposed project (#606143) with a scheduled advertising date of October 2018; however, it is not
currently under design.
Route 27 is a primary east-west route through the City of Brockton. The intersection of Route 27
(Crescent Street)/Quincy Street/Massasoit Boulevard experiences regular emergency vehicle traffic due to
its proximity to Brockton Hospital, located north of the intersection on Route 123 (Centre Street).
Massasoit Boulevard, which intersects Route 27 from the south, is an entrance driveway to Massasoit
Community College. An RSA team member stated that, although the main entrance to Massasoit
Community College is located on Thatcher Street, most traffic accesses Massasoit Community College
using Massasoit Boulevard because it is more easily accessed from regional roadways. Representatives
from Massasoit Community College attending the RSA also stated that, in addition to Massasoit
Community College-related deliveries, heavy vehicle traffic often uses Massasoit Boulevard to access the
used auto parts junkyard on Thatcher Street.
In general, an RSA is intended to identify potential safety improvements that can be evaluated and
included as part of the design process for a future reconstruction project. The short-term, low-cost
potential improvements could be considered by the responsible agency for immediate implementation
prior to reconstruction, as appropriate. The RSA study area is illustrated in Figure 1.
Project Data
The audit team conducted an RSA for the intersection of Route 27 (Crescent Street)/Quincy
Street/Massasoit Boulevard on Monday, June 17, 2013. The RSA agenda appears in Appendix A. Table
1 lists the audit team members and their affiliations. Appendix B provides contact information for all
team members.

Road Safety Audit
Route 27 (Crescent Street)/Quincy Street/Massasoit Boulevard, Brockton, MA
Prepared by Howard/Stein-Hudson Associates, Inc.
Prior to the RSA, in order to begin assessing possible safety issues, the audit team reviewed collision
diagrams and a crash detail summary for the intersection of Route 27/Quincy Street/Massasoit Boulevard
based on crash records supplied by the Brockton Police Department. Between January 2010 and April
2013, 33 crashes were reported at the intersection. Of those crashes, 19 (or 58%) were angle-type
crashes, nine (27%) were rear-end crashes, three (9%) were sideswipe crashes, and two (6%) were singlevehicle crashes. Twenty-one crashes (64%) occurred on dry pavement, 11 (33%) occurred on wet
pavement, and one (3%) occurred on an icy roadway surface. Crashes generally occurred in the daylight
hours (76%). Nine crashes (27%) resulted in personal injury, and no fatalities were reported.
Appendix C provides the detailed crash data for the intersection.
Project Location Description
The RSA focused on the intersection of Route 27/Quincy Street/Massasoit Boulevard in the City of
Brockton, as shown in the aerial image in Figure 2.
Route 27 (Crescent Street)/Quincy Street/Massasoit Boulevard is a signalized intersection with four
approaches. The Route 27 eastbound approach consists of a left-turn lane and a shared through/right-turn
lane. The Route 27 westbound approach consists of a shared left-turn/through lane and an exclusive
right-turn lane. The Massasoit Boulevard northbound approach consists of a single travel lane. The
Quincy Street southbound approach consists of an exclusive left-turn lane and a shared through/right-turn
lane. Sidewalks are provided along the north side of the intersection, but are not provided along the south
side of the intersection. A crosswalk is not provided across the Route 27 westbound approach; however,
crosswalks are provided across the other three approaches. Pedestrian indications are provided across the
Route 27 eastbound approach, but are not provided for the other two crosswalks. Pedestrian ramps are not
provided. During the RSA, which took place during midday hours, the Route 27 eastbound and
westbound phases operated concurrently, while the Massasoit Boulevard northbound approach and
Quincy Street southbound approach operated under split phasing.
This intersection is the junction of the following roadways, which are categorized according to MassDOT
Office of Transportation Planning functional classifications:
Route 27 (Crescent Street) is classified as an urban principal arterial and falls under the City of
Brockton’s jurisdiction. Route 27 is a north-south roadway that originates at Route 106 in Kingston to
the south and terminates in Chelmsford at Route 110 to the north. Within the study area, Route 27 runs in
an east-west direction and typically consists of one travel lane in each direction. Therefore, throughout
this report, Route 27 northbound will be referred to as Route 27 westbound, and Route 27 southbound
will be referred to as Route 27 eastbound. East of Quincy Street, sidewalks are generally provided along
the north side of Route 27 and are generally provided along the both sides of Route 27 west of Quincy
Street. Bicycle accommodations are not provided on Route 27 near the study area.

Road Safety Audit Observations and
Potential Enhancements
Based on RSA team discussions on Monday, June 17, 2013, the RSA team determined that the
intersection of Route 27/Quincy Street/Massasoit Boulevard has the following issues that affect safety:
1.
2.
3.
4.
5.
6.
7.
8.
Access management;
Intersection control and geometry
Sight distance;
Pavement condition and drainage;

Route 27 (Crescent Street)/Quincy Street/Massasoit Boulevard, Brockton, MA
Prepared by Howard/Stein-Hudson Associates, Inc.
Safety Issue #1. Access Management
Observations:
Six of the 33 crashes that were reported at Route 27/Quincy Street/Massasoit Boulevard were
“courtesy crashes”, where, contrary to the rules of the road, a motorist yielded to a vehicle
entering a driveway, which was subsequently hit by a vehicle in an adjacent lane. Five of these
“courtesy crashes” occurred when a Route 27 eastbound vehicle stopped to allow a vehicle to exit
Massasoit Plaza, located at the southwest corner, which was subsequently hit by an unsuspecting
Route 27 eastbound vehicle in the left-turn lane. The Massasoit Plaza exit driveway is located
just 60 feet west of the intersection, so left-turning vehicles exiting the plaza must find a gap in
two lanes of Route 27 eastbound traffic and one lane of Route 27 westbound traffic. A sixth
courtesy crash occurred between a Route 27 eastbound vehicle and a Massasoit Boulevard
northbound vehicle. Three of the six crashes resulted in personal injury.
RSA team members stated that a small curb cut located on the northwest corner of the intersection is used by customers of Christo’s to pick up take-out orders. The driveway is located 35 feet west of the intersection along Route 27 westbound. Motorists may not expect vehicles to be entering this driveway, particularly Route 27 eastbound vehicles, which would enter the driveway from the left-turn lane. One crash involved a vehicle turning left into the driveway and a vehicle traveling along Route 27 westbound. Team
members also noted that any vehicle parked in this driveway
would need to back out of their parking space and into traffic. The driveway is not deep enough to accommodate both parked cars and pedestrian travel along the sidewalk. There is no curbing between
the Christo’s parking lot and
the Quincy Street southbound
approach.
The Christo’s driveway on the
northwest corner of the
intersection is informally used
for take-out orders.
At the northwest corner of the intersection, there is no vertical
barrier delineating the edge of Quincy Street and providing
separation from the Christo’s parking lot. Vehicles are not
prevented from entering or exiting the parking lot by anything
aside from pavement markings. Parking spaces are striped up
to the edge of the roadway, and a sidewalk is not present along
the parking lot. Team members suggested that a portion of the
parking lot is most likely within the City layout. Due to the
layout of the parking lot, the row of parking spaces adjacent to
Quincy Street is only accessible by entering directly from
Quincy Street if the adjacent row of parking spaces were
occupied. It was also stated that vehicles often encroach into
the parking lot in order to enter the Quincy Street southbound
Page 8
Road Safety Audit
Route 27 (Crescent Street)/Quincy Street/Massasoit Boulevard, Brockton, MA
Prepared by Howard/Stein-Hudson Associates, Inc.
through/right-turn lane at the intersection. This, according to team members, discourages users of
the parking lot from using the spaces adjacent to Quincy Street. Three crashes involved vehicles
exiting the Christo’s parking lot and vehicles traveling
along Quincy Street southbound.
The Speedee Oil Change has
four driveways; one of which is
located along the Route 27
westbound approach just 30 feet
from the intersection.
The Speedee Oil Change, located on the northeast corner
of the intersection, has four driveways. Two driveways
are located along Route 27, including one driveway
located approximately 30 feet east of the intersection, and
two on Quincy Street, including one driveway located
approximately 35 feet north of the intersection. Vehicles
entering or exiting the driveways along Route 27 may
conflict with two lanes of queued vehicles. One crash
involved an exiting vehicle turning left onto Route 27
eastbound that was struck by a Route 27 westbound
vehicle.
Maher Bros. Automotive, located on the southeast corner
of the intersection, has two driveways on Route 27, including one driveway located 10 feet east of
the intersection. Although not reflected in the crash data, left-turning vehicles from the Maher
Bros. Automotive west driveway may conflict with two lanes of queued traffic.

Enhancements:
1. In order to reduce the occurrence of courtesy crashes, consider restricting left turns from
commercial driveways located close to the intersection, including left turns from
Massasoit Plaza, the southern driveway from Speedee Oil Change onto Quincy Street, the
western driveway from Speedee Oil Change onto Route 27, and the western driveway
from Maher Bros. Automotive onto Route 27.
2. To help prevent courtesy crashes, work with the owner(s) of Massasoit Plaza and the
adjacent property to determine whether consolidating commercial driveways to the west
of the existing Massasoit Plaza driveway is possible in order to reduce the number of
travel lanes that left-turning vehicles must cross when exiting a driveway.
3. Consider adding an entrance driveway from Massasoit Plaza onto Massasoit Boulevard,
in conjunction with restricting left turns into Massasoit Plaza from Route 27, to allow
vehicles exiting Massasoit Plaza to access Route 27 westbound using the traffic signal at
the intersection.
4. Close the existing Christo’s driveway on Route 27 westbound on the northwest corner of
the intersection to eliminate the occurrence of unexpected vehicles turning left into this
area from Route 27 eastbound.
5. Add curbing and a sidewalk along the Christo’s parking lot on the west side of Quincy
Street. Reconfigure the Christo’s parking lot so that it functions using the defined
driveways onto Quincy Street. Review whether these changes would require changes to
the drainage system.
6. At the Speedee Oil Change, in order to prevent entering and exiting vehicles from
conflicting with queued vehicles or vehicles traveling through the intersection, consider
closing the southern driveway onto Quincy Street and the western driveway on Route 27,
if they are determined to be unnecessary for deliveries. Turning radii should be checked
to ensure that fuel deliveries are not impacted.
7. Consider the feasibility of closing the western driveway at Maher Bros. Automotive,
located on the southeast corner of the intersection, in order to prevent vehicles from
entering or exiting the driveway close to the intersection.

Safety Issue #2. Intersection Control and Geometry
Observations:
The Route 27 eastbound and westbound approaches operate using permissive left turns. The Route 27 eastbound approach has an exclusive left-turn lane, but the Route 27 westbound approach has a shared left-turn/through lane. An RSA team member stated that it is sometimes difficult for Route 27 westbound left-turning traffic to see Route 27 eastbound through traffic due to vehicles waiting in the Route 27 eastbound left-turn lane. Three angle crashes involved vehicles turning left from Route 27 westbound onto Massasoit Boulevard and through traffic on Route 27 eastbound. Because the Route 27 westbound approach has a shared left-turn/through lane, vehicles waiting to turn left feel pressure from queued through vehicles behind them, causing them to take more risks when turning. A left-turn lane is provided on
the Route 27 eastbound
approach, but there is no
protected signal phase.
RSA team members noted that all the approaches to the intersection had one or more lanes that
appear to be too narrow for comfortable travel. Team members stated that vehicles often
encroach into the Christo’s parking lot in order to enter the Quincy Street southbound
through/right-turn lane.
RSA team members noted that there is no overhead signal
indication facing the Route 27 westbound approach to the
intersection. Team members also observed that some of the
Quincy Street southbound signal indications are smaller than
12 inches.
There is no overhead signal
provided on the Route 27
westbound approach.
An RSA team member stated that, while the signal is
actuated and coordinated with the nearby signals to the west,
the coordination is based on timing, the intersections have
separate controllers, and there is no direct communication
between the signals.
Route 27 serves as a major east/west corridor through the City of Brockton, which results in high
volumes of traffic using Massasoit Boulevard to access and egress Massasoit Community
College. This causes long delays on Massasoit Boulevard. RSA team members stated that
motorists on Massasoit Boulevard often get distracted by electronic devices while waiting at the
signal.
While there is significant emergency vehicle activity at the intersection due to its proximity to the
Brockton Hospital, there is currently no emergency vehicle preemption at the intersection.
Page 11
Road Safety Audit
Route 27 (Crescent Street)/Quincy Street/Massasoit Boulevard, Brockton, MA
Prepared by Howard/Stein-Hudson Associates, Inc.
Enhancements:
1. Consider the feasibility of adding a left-turn storage lane at the Route 27 westbound
approach to the intersection to allow Route 27 westbound left-turning vehicles to wait for
an acceptable gap. Consider the impact on turning radii of heavy vehicles turning right
from Route 27 westbound onto Quincy Street.
2. If unable to create a left-turn storage lane on the Route 27 westbound approach, consider
converting the existing shared left-turn/through lane to an exclusive left-turn lane, and
converting the existing exclusive right-turn lane to a shared through/right-turn lane.
3. In order to reduce angle crashes involving Route 27 left-turning vehicles, consider adding
protected/permissive left-turn phasing at the Route 27 eastbound approach and on the
Route 27 westbound approach if an exclusive left-turn lane is provided.
4. Evaluate all approaches and individual lanes to determine if additional width is necessary
for queuing and turning vehicles. If necessary, consider widening the roadway to provide
additional capacity.
5. Provide an overhead signal for the Route 27 westbound approach to improve the visibility of the signal. 6. Replace the existing 8-inch signal heads for the Quincy Street southbound approach with
standard 12-inch signal heads, per Manual on Uniform Traffic Control Devices
(MUTCD) requirements.
7. Consider updating the coordination system between the intersection and the two nearby
intersections at the Brockton East Shopping Plaza to the west in order to improve the
flow of traffic through the Route 27 corridor.
8. Consider implementing adaptive signal control at the intersection in order to improve
signal performance at the intersection.
9. Consider adding advance loop detectors on Massasoit Boulevard to reduce instances of
the signal gapping out due to driver inattention.
10. Provide emergency vehicle preemption at the intersection.

Safety Issue #3. Sight Distance
Observations:
Horizontal curves along the Route 27 westbound approach and the Massasoit Boulevard northbound approach may
impact the sight lines to the signal. Similarly, a crest vertical curve on the Quincy Street southbound approach may impact sight lines of the intersection. Maher Bros. Automotive, which is located on the southeast corner of the intersection, parks cars close to the edge of Massasoit Boulevard. These vehicles may impact the sight lines to the west of the intersection. Enhancements:
A horizontal curve on Route
27 to the east of the
intersection may obscure
sightlines.
1. Provide intersection warning signage (W2-1) along all approaches to the intersection.
2. Provide curve warning signage (W1-2) in advance of the horizontal curves on Route 27
westbound and Massasoit Boulevard northbound. Provide chevrons (W1-8) along both
horizontal curves.
3. Evaluate sight lines to determine if alignment or profile changes are necessary to improve
sight distance at the intersection.
4. Determine if the presence of parked cars at Maher Bros. Automotive presents sight
distance limitations or if vehicles are parked on City right-of-way. If necessary, work
with Maher Bros. Automotive to reach an acceptable layout for parking within the
property.

Route 27 (Crescent Street)/Quincy Street/Massasoit Boulevard, Brockton, MA
Prepared by Howard/Stein-Hudson Associates, Inc.
Safety Issue #4. Pavement Condition and Drainage
Observations:
RSA team members observed that the pavement at the intersection is in poor condition, and that the pavement has rutted in some locations. This may be the result of poor drainage and significant heavy vehicle volume. Eleven of the 33 crashes occurred on wet pavement, and one crash occurred on icy pavement. Three crashes that occurred on wet pavement were reported to involve skidding vehicles. RSA team members stated that ponding occurs at the southwest corner of the intersection. The pavement is in poor
condition, and is rutting in
some locations.
Team members also observed catch basins that were blocked by debris; this indicates the need for additional maintenance of drainage structures to ensure adequate drainage at the intersection. Enhancements:
1. Improve drainage and the occurrence of crashes on wet pavement by maintaining existing
drainage structures.
2. Resurface the intersection and surrounding approaches in order to improve drainage and
vehicle traction on wet pavement.
3. Evaluate the placement of the existing catch basins at the intersection. Consider the need
for additional catch basins and/or resizing of drainage pipes at the intersection,
particularly at the southwest corner of the intersection, to prevent pooling of storm water
and rutting pavement.
4. As part of long-term reconstruction efforts, consider the significant heavy vehicle volume
that would impact the pavement design for the intersection to improve future
performance of pavement.

Route 27 (Crescent Street)/Quincy Street/Massasoit Boulevard, Brockton, MA
Prepared by Howard/Stein-Hudson Associates, Inc.
Safety Issue #5. Signage
Observations:
There is no lane use signage along any of the approaches to the intersection. Lane use signage
may prevent sideswipe crashes that occur when a motorist changes lanes suddenly. One
sideswipe crash occurred along the Route 27 westbound approach to the intersection.
RSA team members noted that there are no street name signs at the intersection, which may cause
confusion and hesitation at the intersection.
Enhancements:
1. Add lane use signage along the Route 27 eastbound, Route 27 westbound, and Quincy
Street southbound approaches to help motorists to enter the appropriate lane in advance
of the intersection.
2. As discussed in Safety Issue #3: Sight Distance, provide intersection warning signage
(W2-1) along all approaches to the intersection, and provide curve warning signage (W12) ahead of the horizontal curves on the Route 27 westbound approach and the Massasoit
Boulevard northbound approach to the intersection.
3. Add street name signage to improve clarity at the intersection.
Page 15
Road Safety Audit
Route 27 (Crescent Street)/Quincy Street/Massasoit Boulevard, Brockton, MA
Prepared by Howard/Stein-Hudson Associates, Inc.
Safety Issue #6. Pavement Markings
Observations:
RSA team members observed that the lane line separating the Route 27 westbound shared left-turn/through lane and exclusive right-turn lane is relatively short. A longer lane line would allow vehicles to queue in their respective
lanes and reduce confusion.
Team members also noted that most of the longitudinal pavement markings along the intersection approaches are faded. There is currently no edge line along Massasoit Boulevard.
The lane line between the shared
left-turn/through lane and rightturn lane is very short, and
pavement markings are faded.
Enhancements:
1. Consider the feasibility of extending the lane line along Route 27 westbound within the
existing layout to increase the amount of vehicles that may queue in separate lanes along
the approach.
2. Update all longitudinal pavement markings with retroreflective thermoplastic for
increased visibility and clarity at the intersection.
3. Provide an edge line along Massasoit Boulevard for increased visibility, particularly in
dark or inclement conditions.

Safety Issue #7. Pedestrian and Bicycle Accommodations
Observations:
While no crashes were reported to have involved
pedestrians or bicyclists, RSA team members noted that pedestrian and bicycle accommodations are missing at the intersection. In the vicinity of the intersection, sidewalks are provided along the north side of Route 27 and along the east side of Quincy Street. However, the sidewalk along Route 27 may
be blocked by vehicles in the Christo’s Route 27 driveway. The sidewalk along the west side of Quincy Street ends at the Christo’s parking lot, and vehicles sometimes encroach into this parking lot to enter the Quincy Street southbound through/right-turn lane queue. This presents a safety issue to pedestrians who would not expect a southbound vehicle to enter the parking lot area. There are no bicycle facilities or
curb ramps at the intersection,
and pedestrian signals are
present at only one of the three
crosswalks.
A crosswalk is provided across the west leg of Route 27 and across Massasoit Boulevard, despite
the lack of sidewalks on the south side of Route 27. A crosswalk is also provided across Quincy
Street. Americans with Disabilities Act (ADA)-compliant pedestrian ramps and push buttons are
not provided. Pedestrian indications are provided across the Route 27 western crosswalk, but not
at the Quincy Street or Massasoit Boulevard crosswalks. Team members noted that the
pedestrian walk time may need to be extended. On the morning of the audit, RSA team members
observed several pedestrians crossing approximately 50’ away from the intersection, between
queued vehicles, but not in the crosswalk.
There are no bike lanes, shoulders, designated shared lanes, or bicycle detection present at the
intersection. Quincy Street does have placards posted by the Massachusetts Department of Public
Works indicating that Quincy Street is a bicycle route. The Claire Saltonstall Bicycle Route,
which extends from Boston to Provincetown, runs along Quincy Street and Massasoit Boulevard
through the Massasoit Community College campus to Thatcher Street.
Page 17
Road Safety Audit
Route 27 (Crescent Street)/Quincy Street/Massasoit Boulevard, Brockton, MA
Prepared by Howard/Stein-Hudson Associates, Inc.
Enhancements:
1. Continue the existing sidewalks on the north side of Route 27 and the west side of
Quincy Street through the intersection.
2. Consider the feasibility of providing a crosswalk across the Route 27 east leg of the
intersection.
3. Upgrade pedestrian ramps and pedestrian push buttons to ADA standards.
4. Confirm that the existing pedestrian walk and flashing don’t walk timings meet MUTCD
standards.
5. Update the signal to include bicycle detection and MUTCD-compliant pedestrian signals
at all crosswalks.
6. As part of long-term reconstruction efforts, consider the feasibility of providing
sidewalks along Massasoit Boulevard and along the south side of Route 27.
7. As part of long-term reconstruction efforts, consider providing bicycle accommodations
along the intersection approaches, particularly along the Saltonstall Bicycle Route,
including bike lanes, a paved shoulder, or shared lane markings.
Safety Issue #8. Distracted Driving
Observations:
RSA team members noted that the Massasoit Boulevard northbound approach to the intersection
has long queues, sometimes into the Massasoit Community College parking lots, during midday
periods after classes are over. An RSA team member said that delays can be exacerbated by
inattentive or distracted motorists.
Enhancements:
1. Work with Massasoit Community College to educate students about laws that prohibit
text messaging while driving and other methods to help improve traffic flow on
Massasoit Boulevard.
2. Massasoit Community College should consider ways to encourage students to use the
Thatcher Street egress from campus.

Recommendations
Based on its review of data, on-site field observations and group discussion, the RSA team identified
the following possible enhancements that could improve safety at the intersection of Route 27
(Crescent Street)/Quincy Street/Massasoit Boulevard. Further study and design work will need to be
conducted to determine the feasibility of making some of the improvements.
Table 2 summarizes the safety issues, possible enhancements, estimated safety payoff, time frame,
cost, and responsibility. Safety payoff estimates are based on engineering judgment and are
categorized as low, medium, and high. The time frame is categorized as short-term (<1 year), midterm (1 to 3 years), or long-term (typically >3 years). Long-term improvements are typically
considered to be substantial improvements with an expected time frame for implementation greater
than 3 years. The costs are categorized as low (<$10,000), medium ($10,001 to $50,000), or high
(>$50,000).
Short-term enhancements include, but are not limited to:

Restrict left turns out of commercial driveways close to the intersection;

Add a left-turn storage lane on Route 27 westbound;

Provide intersection warning signage and street name signs;

Remove obstructions to sight lines;

Maintain existing drainage structures; and

Restripe longitudinal pavement markings.
To enhance the safety of the corridor, the long-term enhancements are to:

Close, relocate, or consolidate commercial driveways;

Increase intersection capacity;

Use curbing to define the edge of roadway on Quincy Street;

Update signals with new equipment and coordination;

Improve drainage;

Provide curb ramps and consistent sidewalks; and

Provide bicycle accommodations.

The RSA is intended to identify potential safety improvements that can be evaluated and included as
part of the design process for a reconstruction project. The short-term, low-cost potential
improvements could be considered by the responsible agency for immediate implementation, as
appropriate.

Table 2. Summary of Potential Safety Enhancements
Safety Issue
Access
Management
Safety Enhancement
In order to reduce the occurrence of courtesy crashes,
consider restricting left turns from commercial driveways
located close to the intersection, including from Massasoit
Plaza, the southern driveway from Speedee Oil Change onto
Quincy Street, the western driveway from Speedee Oil
Change onto Route 27, and the western driveway from
Maher Bros. Automotive onto Route 27.
To help prevent courtesy crashes, work with the owner(s) of
Massasoit Plaza and the adjacent property to determine
whether consolidating commercial driveways to the west of
the existing Massasoit Plaza driveway is possible.
Consider adding an entrance driveway from Massasoit Plaza
onto Massasoit Boulevard, in conjunction with restricting left
turns into Massasoit Plaza from Route 27, to allow vehicles
exiting Massasoit Plaza to access Route 27 westbound using
the traffic signal at the intersection.
Close the existing Christo’s driveway on Route 27 westbound
on the northwest corner of the intersection to eliminate the
occurrence of unexpected vehicles turning left into this area
from Route 27 eastbound.
Add curbing and a sidewalk along the Christo’s parking lot on
the west side of Quincy Street. Reconfigure the Christo’s
parking lot so that it functions using the defined driveways
onto Quincy Street. Review whether these changes would
require changes to the drainage system.
In order to prevent entering and exiting vehicles from
conflicting with queued vehicles or vehicles traveling through
the intersection, consider closing the southern driveway onto
Quincy Street and the western driveway on Route 27 at the
Speedee Oil Change, if they are determined to be
unnecessary for deliveries. Turning radii should be checked
to ensure that fuel deliveries are not impacted.

Consider the feasibility of closing the western driveway at
Maher Bros. Automotive, located on the southeast corner of
the intersection, in order to prevent vehicles from entering or
exiting the driveway close to the intersection.
Consider the feasibility of adding a left-turn storage lane at
the Route 27 westbound approach to the intersection to allow
Route 27 westbound left-turning vehicles to wait for an
acceptable gap. Consider turning radii of heavy vehicles
turning right from Route 27 westbound onto Quincy Street.
If unable to create a left-turn storage lane on the Route 27
westbound approach, consider converting the existing shared
left-turn/through lane to an exclusive left-turn lane, and
converting the existing exclusive right-turn lane to a shared
through/right-turn lane.
In order to reduce angle crashes involving Route 27 leftturning vehicles, consider adding protected/permissive leftturn phasing at the Route 27 eastbound approach and on the
Route 27 westbound approach if an exclusive left-turn lane is
provided.
Evaluate all approaches and individual lanes to determine if
additional width is necessary for queuing and turning
vehicles. If necessary, consider widening the roadway to
provide additional capacity.
Provide an overhead signal for the Route 27 westbound
approach to improve the visibility of the signal.
Replace the existing 8-inch signal heads for the Quincy
Street southbound approach with standard 12-inch signal
heads, per Manual on Uniform Traffic Control Devices
(MUTCD) requirements.
Consider updating the coordination system between the
intersection and the two nearby intersections to the west in
order to improve the flow of traffic through the Route 27
corridor.
