FINAL
Background
The Federal Highway Administration (FHWA) defines a Road Safety Audit (RSA) as the formal safety
examination of an existing or future road or intersection by an independent, multidisciplinary team. The
purpose of an RSA is to identify potential safety issues and possible opportunities for safety
improvements considering all roadway users. A key objective of the RSA is to identify both short-term
and long-term safety improvements that can be made at the subject intersections. This RSA evaluates the
intersection of Route 20 and Grafton Street in Shrewsbury, MA, as shown in Figure 1.
Project Data
A Road Safety Audit was completed for the intersection of Route 20 at Grafton Street in the Town of
Shrewsbury on April 2, 2015. The agenda for the RSA meeting held at Shrewsbury Town Hall is
provided in Appendix A of this report. As shown below in Table 1, the audit team consisted of a
multidisciplinary team with representatives from state, regional and local agencies providing expertise in
the engineering, planning, maintenance and emergency response fields. Contact information for the RSA
attendees is provided in Appendix B of this report.

Project Location and Description
Study Area Roadways
As shown in Figure 1, Route 20 is a four-lane roadway in the vicinity of the Grafton Street intersection
that runs in the east-west direction through the Town of Shrewsbury with a posted speed limit of 40 miles
per hour in both directions. Route 20 provides direct access to retail and industrial land uses as well as a
small interchange with Route 140. The Route 140 interchange is approximately 450 feet east of the Route
20 at Grafton Street intersection. Route 20 is classified as an urban principal arterial under MassDOT
jurisdiction. Within the vicinity of the study area intersection, Route 20 is approximately 44 feet wide
with 11 foot travel lanes. There are no sidewalks present on Route 20, no bicycle facilities, and minimal
shoulder width.
Grafton Street is a two-lane local road under Town of Shrewsbury jurisdiction that runs in a north-south
direction through Shrewsbury. Grafton Street has a single lane of travel in either direction measuring with
a varying width and approximately 11 feet wide at the intersection with Route 20. There is no sidewalk or
shoulder present on Grafton Street.
Study Area Intersections
The intersection of Route 20 at Grafton Street is a four-legged signalized intersection maintained by
MassDOT. The eastbound and westbound approaches both consist of a shared thru-left and shared thruright travel lane. The northbound and southbound approaches both consist of a single multi-use lane. The
traffic signals are mounted on a span wire that stretches from the southeast to northwest corner of the
intersection. In the northeast corner of the intersection there is a driveway opening providing access into a
gas station (Flynn’s Truck Stop) that at times effectively creates a fifth leg at the intersection. There are
no pedestrian crosswalks or signals at the intersection. East of the intersection on Route 20 there are
driveways for Flynn’s Truck Stop and a UPS shipping facility which generate a large amount of truck
traffic.
Crash Data
Crash data was received from MassDOT for the three years between 2010 and 2012. Based on this data,
there were a total of 49 crashes reported from the beginning of 2010 through the end of 2012 at the
intersection of Route 20 and Grafton Street. Of the crashes that occurred, 27 (55%) were angle collisions,
including nine crashes in the eastbound direction and 11 crashes in the westbound direction on Route 20.
Additionally, there were nine rear-end collisions, eight sideswipe crashes, two single vehicles crashes,
one head-on crash, and two “other” crash types reported at the intersection. Of the reported crashes, 39
resulted in property damage and 10 resulted in personal injury; no fatalities were reported at the
intersection.
Detailed crash diagrams are provided in Appendix C.

FINAL
Road Safety Audit Observations and Potential
Improvements
During the RSA meeting, a brief introduction of the RSA process and a summary of the study area and
crash information were presented to the audit participants. Following this brief presentation, the members
of the audit team were asked to discuss the existing issues that may affect safety at the intersection of
Route 20 at Grafton Street. Provided below is a list of the safety concerns that were identified during the
RSA along with potential enhancements that address these concerns.
Safety Issue #1: Access Management
Observations:
Route 20 near Grafton Street provides direct access to multiple commercial and industrial properties.
Observations during the RSA indicate that curb cuts on Route 20 are quite large. There are a number of
access points within the functional area of the Grafton Street intersection, and there is direct access into
Flynn’s Truck Stop in the northeast corner of the intersection. In addition, many of the industrial land
uses generate a high number of heavy vehicles. On the southern side of Route 20, across the street from
Flynn’s Truck Stop, there are parking facilities for trucks that creates a desire line across Route 20 for
vehicles and pedestrians. Eastbound traffic frequently makes left turns into Flynn’s Truck Stop and the
UPS shipping center. During the field visit RSA members observed eastbound trucks slowing to turn in
the left lane and forcing vehicles to merge into the right lane, which becomes a right-turn only lane for
access to Route 140. At the curb cuts along Route 20, there was no signage observed to direct patrons on
where to enter or exit.
Enhancements:
• Work with the adjacent land owners to consolidate curb cuts within the functional area of the
intersection while still providing adequate site access.
• Have adjacent land owners install signage to better direct patrons on where to enter and exit their
sites.
• Close the driveway that creates a fifth leg within the Grafton Street intersection at the northeast
corner.
• Create a dedicated eastbound left-turn lane and add protected signal phasing to better consolidate
eastbound left turn traffic.
• Encourage coordination between MassDOT, Town officials, and adjacent property owners,
specifically the UPS shipping center, to better understand their future access plans, and
collaborate with each other to provide safe and efficient access to sites adjacent to the
intersection.
• Evaluate the possibility of creating truck access on Route 140 to the UPS shipping center
• Evaluate revised signal timing plans that prioritize access on Grafton Street during peak truck
periods.
Safety Issue #2: Pedestrian Accommodations
Observations:
The intersection of Route 20 at Grafton Street does not currently provide crosswalks, sidewalks, or
pedestrian signals. During the RSA, it was noted that pedestrians cross between Flynn’s Truck Stop, the
truck parking lots on the south side of Route 20 and Brody’s Diner. Flynn’s Truck Stop provides a fullservice truck stop with amenities for long-distance truckers. The residential neighborhoods on the north

FINAL
and south side of Route 20 lack pedestrian
connectivity due to the lack of pedestrian amenities on
Grafton Street and the operations on Route 20
effectively acting as a barrier.
Enhancements:
• Evaluate the installation of a crosswalk at the
intersection of Route 20 and Grafton Street.
• Install pedestrian signals and push button
actuation at the signalized intersection.
• Construct sidewalks adjacent to the
intersection to guide pedestrians to the traffic
signal.
No crosswalks for pedestrians at Route 20 and
Grafton Street intersection
Safety Issue #3: Roadway Conditions
Observations:
The RSA team, specifically the members from the Town of Shrewsbury, provided insight on the
conditions along Route 20 near Grafton Street. In general, the roadway serves as an overflow route from
the Massachusetts Turnpike and was recognized to have a speed issue. Speeding is an issue on this section
of roadway, which may be influenced by the significant downgrade heading eastbound. It was noted that
the large volumes of truck traffic significantly impact the roadway. The roadway surface shows rutting
from the heavy vehicles and first responders noted that they often encounter crashes caused by oily truck
residue collected on the roadway. During the past winter, snow storage was a problem at the intersection,
but in previous winters, the issue was minimal.
Enhancements:
• Setup a speed trailer in the eastbound direction
to show drivers their current travel speeds and
encourage speed limit compliance.
• Provide enhanced enforcement along the
corridor to slow drivers down.
• Evaluate and construct a special pavement
surface that can withstand heavy vehicle
loading.
• Evaluate and implement a high friction
pavement surface treatment to counter the
reduced friction from truck residue.
Rutting created by heavy vehicles on Route 20
Safety Issue #4: Traffic Control
Observations:
Traffic control at the intersection of Route 20 and Grafton Street is impacted by the traffic signal, access
to nearby land uses, and the Route 140 ramps. During the RSA field visit, the team noticed that the signal
post in the northeast corner had been knocked down, leaving the northbound approach with only one
functioning signal indication. In addition, the overhead signal facing Grafton Street northbound was
angled upward and there were no back plates on any of the overhead signals. East of the intersection, the
right lane becomes a “right turn only” lane onto the Route 140 ramp without advanced warning signage,
although “skip line” lane striping has been installed in advance of the ramp. As mentioned before, the left

FINAL
lane is often used for left-turn access into Flynn’s Truck Stop and the UPS shipping center, which causes
vehicles to merge into the right lane, and then swerve
back to the left lane to continue on Route 20
eastbound. The RSA team observed this pattern during
the site visit. In addition to these observations, the
crash data showed that 55% of reported crashes at the
intersection were angle collisions. It was noted by the
RSA participants that the Grafton Street signal often
doesn’t get adequate time to clear queues during the
rush hours.
Enhancements:
Tilted sign face and missing signal post on
• Replace the post-mounted signal head at the
Grafton Street northbound
northeast corner of the intersection as a shortterm measure.
• Re-adjust the position of the overhead signal for Grafton Street northbound to improve visibility.
• Check the functionality of signal detection on Grafton Street and repair as needed.
• Install backplates with reflective borders for overhead signals facing the Route 20 eastbound and
westbound approaches to minimize the effects of solar glare.
• Re-evaluate the clearance intervals in consideration of the heavy vehicle traffic and significant
grades.
• Evaluate a redesign of the signal system at the intersection, which will improve signal head
placement and facilitate emergency preemption and dilemma zone detection to improve
emergency response and decrease crash risks.
• Consider installation of dedicated left turn lane at the signal and/or along the corridor to reduce
angle collisions.
• Re-evaluate the pavement striping plan and install corresponding lane utilization signage to
mitigate the right-lane trap created by the Route 140 on-ramp.
• Install lane utilization signage eastbound in advance of the signal to alert drivers of the right turn
lane ending.
• Consider implementing a left-turn prohibition during peak hours to reduce turn-related crashes.
Safety Issue #5: Traffic Operations
Observations:
The intersection of Route 20 and Grafton Street is
impacted by traffic operations on the Route 20
corridor. The RSA team mentioned the variable cross
section along Route 20, steep roadway grades, a
significant amount of heavy vehicle traffic, and
congestion in the afternoon peak hour as operational
challenges for Route 20 that impact the Grafton Street
intersection. Route 20 has a crest in the roadway about
600 feet west of the Grafton Street intersection before
sloping downhill eastbound through the intersection
and toward the Route 140 interchange. For the
Crest on Route 20 west of Grafton Street
intersection
Page 6
Road Safety Audit—Route 20 at Grafton Street - Shrewsbury, MA
Prepared by McMahon Associates, Inc.
FINAL
eastbound traffic, the crest in the hill could potentially make it difficult to perceive the signal at Grafton
Street. Within that section of roadway, the westbound direction (going uphill) transitions from two lanes
down to one which doesn’t provide enough space to pass slow moving trucks. The roadway grades and
land uses both create merging issues with trucks within the functional area of the intersection; tractor
trailers traveling eastbound that are in the right lane prior to the crest need to change lanes east of the
intersection unless they are destined for Route 140. Trucks turning out of driveways on Route 20 were
often seen crossing the double yellow centerline into oncoming traffic to complete turns, which could
indicate insufficient curb radii at the driveways and side streets.
Enhancements:
• Install a “Lane Ends” sign where the westbound lane drops, west of the Grafton Street signal.
• Install a “(Red) Signal Ahead” LED blank-out sign at the crest of the roadway in the eastbound
direction that is tied to the signal at Grafton Street.
• Evaluate the extension of two westbound receiving lanes up the hill west of the intersection to
remove the lane drop on an uphill section of roadway.
• Evaluate existing right-of-way restrictions and proposed widening improvements where feasible
to create a consistent cross section along Route 20.
• Evaluate curb radii along Route 20 at the Grafton Street intersection and at nearby driveways to
determine if modifications are needed to facilitate turning movements for heavy vehicles.
Recommendations
After the discussing the various safety deficiencies within the study area, participants discussed potential
solutions. The audit participants were encouraged to consider both short and long-term improvements for
each of the existing safety issues. Each improvement considered has been categorized as short-term, midterm, or long-term based on the definitions shown in Table 2. Additionally, a cost category has been
