Background
The intersection of Weymouth Street/Pine Street/Sycamore Street in Holbrook, Massachusetts, is listed as
a High Crash Location within the Metropolitan Area Planning Council (MAPC) region. The intersection
is also listed as #167 on The Massachusetts Department of Transportation’s (MassDOT)list of the 200
Statewide Top Crash Locations from 2009-2011. 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 the proposed design incorporated the safety improvements
identified in the RSA. The intersection is currently under design (MassDOT Project #607225), but is not
currently on the Transportation Improvement Program (TIP).
In general, the RSA is intended to identify potential safety improvements that can be evaluated and
included as part of the design process for the future reconstruction of the intersection. 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.

Prior to the RSA, in order to begin assessing possible safety issues, the audit team reviewed the collision
diagram and a crash detail summary for the intersection of Weymouth Street/Pine Street/Sycamore Street
based on crash records supplied by the Holbrook Police Department. Forty-eight crashes were reported,
and documented by the Holbrook Police Department, at the intersection from 2007-2012. It should be
noted that complete data was only available for the years 2008-2010, so more crashes may have occurred
in 2007, 2011, and 2012 than was reported. Of the 48 crashes reported, 39 (or 82%) were angle crashes,
three (6%) were single-vehicle crashes, three (6%) were head-on crashes, two (4%) were rear-end
crashes, and one (2%) was a sideswipe crash. Thirty-five crashes (73%) occurred in the daylight, and 28
(58%) occurred on dry pavement. Of the 48 crashes, 26 (or 54%) resulted in personal injury. No
fatalities were reported.
At the time of the audit, Weymouth Street was being resurfaced between the intersection and Route 139,
and the south leg of Weymouth Street was closed to through traffic. As a result, the traffic volumes and
motorist behavior at the intersection during the audit was likely not representative of the typical
conditions at the intersection. However, local representatives were able to provide input relative to typical
conditions at the intersection.
Appendix C provides the detailed crash data for the intersection.

Project Location Description
The RSA focused on the intersection of Weymouth Street/Pine Street/Sycamore Street in the Town of
Holbrook, as shown in the aerial image in Figure 2.
Weymouth Street/Pine Street/Sycamore Street is a two-way stop-controlled intersection. The Weymouth
Street eastbound and westbound approaches to the intersection allow for free movement through the
intersection, while the Sycamore Street northbound and Pine Street southbound approaches are stopcontrolled. The stop signs appear to be relatively new, and are oversized and equipped with
retroreflective tape. The stop condition is reinforced with a flashing red beacon; the Weymouth Street
eastbound and westbound approaches are alerted to the intersection by flashing yellow beacons. The
overhead flashing beacon at the intersection was upgraded in 2012 with larger, LED lights. The oversized
stop signs at the intersection appear to have been placed relatively recently, and are equipped with
retroreflective red tape along the post for added visibility. Public works officials attending the RSA
stated that these upgrades may have occurred because the signs needed to be replaced after being hit.
This intersection is the junction of the following roadways, which are categorized according to MassDOT
Office of Transportation Planning functional classifications:
Weymouth Street is an urban minor arterial and falls under the Town of Holbrook’s jurisdiction.
Weymouth Street runs northeast-southwest between Route 139 (Abington Avenue) to the southwest and
the Weymouth Town Line to the northeast, where it becomes Randolph Street. Weymouth Street consists
of one travel lane in each direction. Sidewalks are provided along the north side of Weymouth Street. On
the day of the audit, Weymouth Street was closed to vehicular traffic for resurfacing west of the
intersection, where new sidewalks were also being installed along the south side of the roadway.
Dedicated bicycle accommodations are not provided on Weymouth Street. The posted speed limit along
Weymouth Street is 35 mph.
Pine Street is an urban minor arterial and falls under the Town of Holbrook’s jurisdiction. Pine Street
runs northwest-southeast between Weymouth Street and the Braintree Town Line to the northwest. Pine
Street consists of one travel lane in each direction. Sidewalks are provided along the west side of the
roadway, and narrow shoulders are provided, though they are not consistently wide enough to be
considered an adequate bicycle accommodation. The speed limit along Pine Street is 25 mph.
Sycamore Street is an urban collector that falls under the Town of Holbrook’s jurisdiction. Sycamore
Street runs northwest-southeast between Weymouth Street and Route 139 (Abington Street) to the
southeast. Sidewalks are provided along the west side of the roadway, and narrow shoulders are
provided, though they are not consistently wide enough to be considered an adequate bicycle
accommodation. The speed limit along Sycamore Street is 30 mph.

Road Safety Audit Observations and
Potential Enhancements
Based on RSA team discussions on Friday, September 27, 2013, the RSA team determined that the
intersection of Weymouth Street/Pine Street/Sycamore Street has the following issues that affect safety:
1.
2.
3.
4.
5.
Sight Distance;
Speed;
Signage;
Pavement Markings; and
Bicycle Accommodations.
The following sections describe in more detail the safety issues and potential enhancements identified
during the RSA. Several of these issues require further study and engineering judgment to determine the
feasibility of implementing enhancements to address them.
Page 7
Road Safety Audit
Weymouth Street at Pine Street/Sycamore Street, Holbrook
Prepared by Howard/Stein-Hudson Associates, Inc.
Safety Issue #1. Sight Distance
Observations:
The intersection of Weymouth Street/Pine
Street/Sycamore Street is located on a crest
vertical curve along the Weymouth Street
alignment. The resulting steep down grade
along Weymouth Street in the easterly
direction significantly limits sight lines east
of the intersection. Sight lines to the east of
the intersection are further obstructed by the
presence of vegetation, utility poles, and
residential buildings at the northeast and
southwest corners of the intersection.
Sightlines to the east of the intersection are
obscured by a significant vertical curve and,
to a lesser extent, overgrown vegetation.
Thus, motorists approaching the intersection
from Weymouth Street westbound have
difficulty seeing other vehicles at the intersection until shortly before arriving at the intersection.
Similarly, vehicles waiting at the Pine Street southbound and Sycamore Street northbound stop
lines have difficultly determining when it is safe to enter the intersection due to the obstructed
sight lines caused by the grade change.
Of the 48 crashes reported at the intersection, 39 were angle crashes, including 25 crashes
involving Weymouth Street westbound traffic and Sycamore Street northbound or Pine Street
southbound traffic. Public safety officials stated that the lack of adequate sight lines to the east of
Sycamore Street and Pine Street causes
motorists crossing Weymouth Street to focus on
Weymouth Street westbound traffic, rather than
Weymouth Street eastbound, resulting in
crashes with Weymouth Street eastbound
vehicles. Fourteen crashes involved Weymouth
Street eastbound traffic and crossing traffic
from Pine Street or Sycamore Street.
Six of the 48 crashes reported at the intersection
involved vehicles that failed to stop at a stop
sign. This may indicate that Sycamore Street
Pine Street and Sycamore Street are stopcontrolled; Weymouth Street allows for free
northbound and Pine Street southbound
movement through the intersection.
vehicles sometimes roll through the stop line
into the intersection for better sight lines of
Weymouth Street through traffic. Additionally, according to the crash reports, 13 of the 39 angle
crashes involved Sycamore Street northbound or Pine Street southbound vehicles that stopped at
the stop sign but still collided with Weymouth Street through traffic, indicating that there are
Page 8

sight distance issues from the stop lines on Sycamore Street northbound and Pine Street
southbound.
Three head-on crashes occurred between Weymouth Street eastbound and westbound vehicles.
Two of these crashes involved a Weymouth Street eastbound vehicle that was attempting to turn
left onto Pine Street. The vertical curve along the Weymouth Street westbound approach may
have made it difficult for Weymouth Street eastbound left-turning vehicles to see oncoming
traffic.
All of the intersection approaches are wide enough to accommodate two vehicles side-by-side.
One crash occurred when a Weymouth Street eastbound vehicle passed a stopped eastbound
vehicle on the left, assuming it was turning right, but was actually turning left. RSA team
members noted that vehicles stopping side-by-side on Sycamore Street northbound or Pine Street
southbound may further impact sightlines.
Two crash reports stated that snow banks or snow removal equipment near the intersection
obstructed sight lines.
Page 9

Weymouth Street at Pine Street/Sycamore Street, Holbrook
Prepared by Howard/Stein-Hudson Associates, Inc.
Enhancements:
1. Clear vegetation, as appropriate, at the northeast and southeast corner of the intersection to
improve sight lines.
2. Ensure that snow banks do not obstruct sight lines.
3. Evaluate the appropriateness, per current Manual on Uniform Traffic Control Devices
(MUTCD) standards, of implementing four-way stop control at the intersection in the shortterm to reduce the occurrence of angle crashes due to the limited sight distance east of the
intersection. Consider the tradeoff between increased safety and decreased intersection
operations as a result of requiring Weymouth Street traffic to stop. If four-way stop control is
implemented, consider the need to provide “Stop Ahead” (W3-1) signage along all
approaches, especially on the Weymouth Street westbound approach, where a stop sign may
not be immediately visible to motorists.
4. As part of long-term reconstruction efforts, consider installing a modern roundabout or full
signal at the intersection to provide a safe, controlled movement through the intersection and
to reduce the occurrence of angle crashes. Consider the tradeoff between increased safety
and decreased intersection operations as a result of the implementation of a roundabout, and
consider that a signal may not completely eliminate the occurrence of severe angle crashes, as
a roundabout would. If a signal is installed, evaluate the placement of the indications with
respect the vertical curve to ensure visibility for the Weymouth Street westbound approach.
Also consider the need for prohibiting right turns on red on the Pine Street southbound
approach, given the lack of sight distance to the east.
5. As part of long-term reconstruction efforts, evaluate the feasibility of lowering the profile of
the intersection so that Weymouth Street westbound vehicles are more visible to crossing
traffic from Sycamore Street northbound and Pine Street southbound.
6. Consider narrowing the approaches to the intersection using pavement markings, in the shortterm, to show that vehicles are intended to form only one lane.

Safety Issue #2. Speed
RSA team members stated that vehicle travel speeds along Weymouth Street often exceed the
posted speed limit of 35 mph. Weymouth Street eastbound and westbound vehicles are allowed
free movement through the intersection, which, according to public safety officials who attended
the RSA, can result in high speeds along Weymouth Street through traffic which serves as an
important east-west connection through the area between Weymouth and Route 18 to the east and
Route 139 to the west. The speed of Weymouth Street traffic can make it difficult to judge an
adequate gap for crossing vehicles, especially considering the lack of sight distance to the east of
the intersection.
Three head-on crashes occurred between Weymouth Street eastbound and westbound traffic; in
all three cases, the crash report stated that one vehicle may have been speeding. Travel speed
may have also contributed to the three single-vehicle crashes that occurred, all of which involved
Weymouth Street eastbound or westbound vehicles.
High travel speeds have also contributed to more severe crashes at this location, according to
public safety officials. Of the 48 crashes reported at the intersection, 26 resulted in personal
injury.
Public safety officials attending the RSA stated that it is difficult to enforce traffic violations in
the vicinity of the intersection due to a lack of a hidden space to park near the intersection.
Enhancements:
1. Consider the use of radar speed signs to alert motorists of their travel speed.
2. Increase police presence near the intersection, where possible, to slow traffic approaching the
intersection.
3. As part of long-term planning efforts, consider providing a place for public safety officers to
park in order to enforce traffic violations.

Safety Issue #3. Signage
Observations:
Team members observed that the intersection
warning signage showing “Warning
Intersection Ahead” along the Weymouth Street
eastbound and westbound approaches is
outdated per current MUTCD standards, and
appears to be faded.
Enhancements:
1. Replace outdated “Warning Intersection
Ahead” signage with MUTCD-compliant
diagrammatic intersection warning signage
(W2-1) on the Weymouth Street eastbound
and westbound approaches. Consider
placing intersection warning signage on
each side of the approach for emphasis.
Outdated signage states “Caution
Intersection Ahead” along Weymouth
Street eastbound and westbound.
Safety Issue #4. Pavement Markings
Observations:
RSA team members noted that all of the
approaches to the intersection have pavement
markings reading “SLOW”; however, these
markings may not be appropriate on stopcontrolled approaches.
Enhancements:
1. On the Sycamore Street northbound and
Pine Street southbound approaches, replace
existing pavement markings reading
Pavement markings reading “SLOW” are
“SLOW” with pavement markings reading

awareness of the downstream stop sign.
approaches.
Consider the need to replace these
markings along the Weymouth Street eastbound and westbound approaches if the intersection
is converted to four-way stop control in the short-term.

Safety Issue #5. Bicycle Accommodations
Observations:
Dedicated bicycle accommodations are not provided at the intersection. Shoulders are generally
provided along all approaches, but they are not consistently wide enough to be considered an
adequate bicycle accommodation. During the RSA, some bicycle traffic was observed at the
intersection.
Enhancements:
1. As part of long-term planning efforts, consider the appropriateness of providing bicycle lanes
or consistent shoulders for bicycle use along all approaches to the intersection.

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 Weymouth
Street/Pine Street/Sycamore Street. 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), mid­
term (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:
� Remove obstructions to sight lines;
� Implement four-way stop control at the intersection;
� Narrow approaches to one lane using pavement markings;
� Reinforce speed limits with signage;
� Replace outdated signage; and
� Replace “SLOW” pavement markings with “STOP AHEAD” markings on stop-controlled
approaches.
To enhance the safety of the corridor, the long-term enhancements are to:
� Implement a full signal or roundabout at the intersection;
� Lower the profile of the intersection; and
� Provide bicycle accommodations.
It is the responsibility of MassDOT to ensure that the designer incorporates the relevant safety
enhancements identified as part of this RSA. The RSA is intended to identify potential safety
improvements that can be evaluated and included as part of the design process for the reconstruction.
The short-term, low-cost potential improvements could be considered by the responsible agency for
immediate implementation, as appropriate.
