Background
The Federal Highway Administration 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 Road Safety Audit was scheduled for the intersection of Route 101 with Corey Hill
Road and Williams Road in Ashburnham because it has been identified as a high crash location within the
Montachusett Regional Planning Commission (MRPC) region. This location is eligible for Highway
Safety Improvement Project funding as well as High Risk Rural Road Program funding. The RSA is
intended to identify potential short and long term safety improvements that can be made at the intersection,
which can then be implemented through general maintenance for short term low cost improvements or
potentially incorporated into a reconstruction project for longer term measures. A resurfacing project is
scheduled for a 4.5 mile segment of Route 101 in 2014, including the project intersection. Recommended
improvements can be incorporated into that project to the greatest extent practicable, or packaged and
initiated as a separate project.
Project Description
The intersection of Route 101 with Corey Hill Road and Williams Road, shown in Figure 1, is located in
the southern portion of Ashburnham. Route 101 is a north-south route but generally follows an east-west
alignment through the intersection; for clarity purposes, this report will refer to it as an east-west route.
The east leg, Central Street, connects to Ashburnham’s town center approximately 1.1 miles east of the
intersection. The west leg, Center Street, provides a connection from Ashburnham to Route 140 and the
City of Gardner to the southwest. It was noted that the majority of traffic from Route 2 to Ashburnham
travels through the intersection, either via Route 140 and Route 101 or via local roads to Williams Road.
Route 101 is functionally classified as a Rural Major Collector and is under Town of Ashburnham
jurisdiction. Williams Road and Corey Hill Road are both Rural Minor Collectors under town
jurisdiction. Land use in the area is primarily residential. A residence on the southwest corner of the
intersection directly abuts both Center Street and Williams Road, while residences on the northwest and
northeast corners have wooded buffers between the home and the intersection. The southeast corner is an
undeveloped, wooded parcel. Ashburnham’s
post office is located on Central Street
approximately ¼ mile east of the intersection,
and the town’s police and fire headquarters are
located just east of the post office.
The intersection is a 4-way intersection, with
Williams Road and Corey Hill Road under
STOP sign control. A 4-way flashing beacon is
mounted overhead in the center of the
intersection, displaying a flashing yellow
indication to Route 101 and a flashing red
Williams Road approach to Route 101

indication to Williams Road and Corey Hill Road. Route
101 provides a single travel lane in each direction along its
length, following a generally hilly, wooded alignment with
sparsely spaced residences. Williams Road provides a single
travel lane in each direction, widening at the approach to
Route 101 to provide a shared left-through lane and an
exclusive right turn lane. A lane use sign is provided
indicating the intended lane assignments, but corresponding
pavement markings are faded. It was noted that the right turn
Lane use sign on Williams Road
lane was once marked with cross-hatch markings in an
attempt to prohibit use because of visibility issues created by right-turning vehicles. It was subsequently
noted that the prohibition was not adhered to and that the operational and queuing concerns indicated a
need for the added capacity of the right turn lane. A larger STOP sign provided for Williams Road
provides increased visibility for approaching vehicles. Corey Hill Road approaches the intersection on a
downhill grade and provides a single travel lane in each direction, but is wide enough at the stop line to
allow separation between a right-turning vehicle and a left-turning or through vehicle.
Pavement markings are extremely faded to the point of being indistinguishable on Route 101. Centerlines
and stop lines are barely visible on Williams Road and Corey Hill Road. No sidewalks or crosswalks are
provided in the vicinity of the intersection. Poor pavement conditions were noted, including shoulder
deterioration and uneven surfaces. A recent water main burst in the northwest quadrant of the intersection
left a 5’x5’ break in the pavement which was filled in with dirt on the day of the audit. Severe
deformation of the pavement was observed in the middle of the intersection, potentially due to the
liquefaction of soils under the roadway as a result of the water main break. Town personnel noted that the
dirt patch was to be repaired the week of the audit.
Crash data provided by the Ashburnham Police Department and summarized by MassDOT show 21
crashes from December 2009 to November 2012. A collision diagram and crash summary are included in
the Appendix. The prevalent crash type were angle crashes, comprising 71% of total crashes. 23% of the
crashes involved drivers aged 20 and under; the proximity of the high school and higher percentage of
inexperienced drivers is a likely factor. Thirteen crashes involved vehicles exiting Williams Road. Seven
of the thirteen crashes involved a vehicle traveling west on Route 101, while the remaining six involved
an eastbound vehicle. Crashes likely result from limited visibility of approaching traffic based on the
topography of the area, exacerbated by vehicle speeds along Route 101. Two crashes were attributed to
limited visibility from a vehicle in the turn lane.
Three additional angle crashes involved vehicles exiting Corey Hill Road – two with a vehicle traveling
westbound on Route 101, and one with an eastbound vehicle. Two crashes at the intersection involved a
vehicle running off the road and hitting a fixed object; one struck a pole on the southwest corner, the other
struck a guardrail on the southeast corner. The majority of crashes occur during the afternoon hours,
potentially indicating that solar glare is a factor. It should also be noted that six of the 21 total crashes, or
29%, occurred under wet, snowy or icy road conditions.
Speed regulations maintained by MassDOT Highway Division establish a 35 MPH speed limit for Route
101 in the vicinity of the intersection. Complete speed regulations are included in the Appendix.

Audit Observations
Following a brief introduction to the RSA process and a summary of existing crash information, the audit
participants were asked to discuss safety issues at the intersection of Route 101, Williams Road and
Corey Hill Road. Audit participants then conducted a site visit as a group, at which time they offered
observations on safety issues and concerns. A summary of those major safety considerations is as follows:

Visibility – Horizontal curves in advance of the intersection on both Route 101 approaches limit
visibility for vehicles departing Williams Road and Corey Hill Road and for vehicles approaching on
Route 101. This is likely the primary factor in angle crashes at the intersection. It was noted that trees
have been trimmed at the intersection to improve sight lines. Several specific items related to
visibility were identified by the audit team:
o
The guardrail on the southeast corner may also contribute to visibility restrictions for
drivers looking east from Williams Road.
o
A picket fence, granite pillars and utility poles on the southwest corner contribute to
visibility constraints for drivers looking west from Williams Road. It was noted that the
fence and granite pillars were erected by the homeowner following a crash in which a
vehicle came to rest on their property.
o
Vehicles stacked side by side on the two lane Williams Road approach can block each
other’s visibility, and was cited as a specific cause of two crashes at the intersection. In
addition, vehicles pass the stop line on Williams Road and Corey Hill Road to assess
whether it is safe to enter the intersection due to the limited visibility.

Queues – It was noted that vehicle queues exist on Corey Hill Road in the morning peak period and
on Williams Road during school departure times and in the afternoon commuter peak. An elementary
school, middle school and regional high school are all located on or near Williams Road south of
Route 101, and most buses travel through the intersection as part of their route to and from the
Page 5
Road Safety Audit—Route 101(Center St)/Corey Hill Rd/Williams Rd—Ashburnham, MA
Prepared by BETA Group, Inc.
schools. One crash at the intersection during the study period involved a school bus. Queues and
increased delays during peak periods may cause drivers to take chances on unacceptable gaps,
exacerbating concerns relating to visibility constraints.




Solar Glare – Solar glare was noted to be a concern at the intersection, specifically during the
afternoon in the winter months.
Pavement Markings - Pavement markings are faded to non-existent at the intersection. This is
especially of concern for the two lane Williams Road approach.
Intersection Awareness – “Dangerous Intersection” signs are located in advance of the intersection,
but their effectiveness was questioned by the audit team. The sign on the Route 101 westbound
approach is leaning away from the roadway, further reducing its effectiveness.
Speed- Speeding along Route 101 was noted as a safety concern. Speed can also be a contributing
factor with visibility in the crash history of the intersection, as drivers may misjudge the speed of an
approaching vehicle and take a chance on an unacceptable gap.

Turning Radius – It was noted that larger vehicles, including school buses, encroach on westbound
traffic when making a right turn from Williams Road to Route 101 eastbound. This is likely due to
both the tight radius of the corner as well as the lack of shoulder and defined markings on Williams
Road, which may force turning vehicles to the right edge of pavement before turning.

Contributing Factors – While not specifically identified as safety issues, a number of items were
mentioned by audit participants as contributors to traffic at the intersection and items that should be
considered as part of any redesign of the intersection.
o
The previously discussed proximity of schools generates a significant amount of school
bus traffic in the morning and the mid-afternoon. Schools also generate traffic from
parents dropping off children, as well as high school students that drive themselves to
school. It should be noted that 23% of crashes at the intersection involved drivers
between the ages of 17 and 20.
o
Despite the lack of pedestrian and/or bicycle facilities, Route 101 experiences a fair
amount of pedestrian, jogger and bicycle activity.
o
The Ashburnham post office located ¼ mile east of the intersection generates traffic
through the intersection, especially on Saturday.
o
An industrial park nearby in Gardner generates truck traffic along Route 101 through the
intersection.
o
The Ashburnham Public Safety Building is located a ¼ mile east of the intersection;
police, fire and EMS vehicles regularly travel through the intersection to respond to
emergency calls.

Potential Safety Enhancements
Audit participants identified safety issues and recommended potential improvements to address these
issues. Audit participants were encouraged to consider both short and long term improvements for each
issue. Each improvement considered has been categorized as short-term, mid-term, or long-term based on
the definitions shown in Table 2. Additionally, a cost category has been assigned to each improvement
based on the parameters set forth in Table 2.

Consider overall improvement strategies related to traffic control. Two distinct strategies were
discussed at the audit and are detailed below. Both strategies would reduce reliance on the driver
determining the proper gap acceptance. Further study is necessary to determine the appropriateness
and impact of either recommendation. Development of either recommendation must consider the
contributing factors discussed by the audit team and outlined in this report.
o
Consider a roundabout. A roundabout concept was discussed by the audit team. A letter
was sent to Town officials from the homeowner on the southeast corner of the
intersection stating concerns over property acquisition required to accommodate
improvements at the intersection. It was suggested by audit participants that the center of
the roundabout could be shifted slightly to the east from the center of the existing
intersection. Installation of a roundabout would help calm traffic on Route 101,
increasing awareness of the intersection and addressing visibility and gap acceptance
issues, while giving side street traffic greater opportunity to enter traffic on Route 101. A
roundabout is a long-term, high cost improvement which requires further study and
determination of property impacts.
o
Consider installation of a traffic signal. A traffic signal would stop traffic on Route 101 to
allow traffic from Williams Road and Corey Hill Road to enter, and would also increase
awareness of the intersection for vehicles approaching on Route 101. Installation of a
traffic signal would require further study, which includes but is not limited to warrant
analysis, to determine if a traffic signal at this location is an effective safety
countermeasure. Recent traffic volume data were not available, but Town officials noted
that traffic volumes have noticeably increased in the last five years. Installation of a
traffic signal is a long-term, high cost improvement. A traffic signal installation should
include emergency preemption equipment due to the proximity of the police and fire
stations.
Review property plans to determine if the picket fence and granite pillars on the southeast corner of
the intersection are on private property. If these items are within the town-owned right-of-way, they
Page 7
Road Safety Audit—Route 101(Center St)/Corey Hill Rd/Williams Rd—Ashburnham, MA

should be relocated onto the homeowner’s property. This is a short-term, low cost improvement. It
was suggested that they are on the homeowner’s property, but this should be reviewed to be certain.


Continue to trim vegetation along Route 101. It was noted that existing vegetation is consistently
maintained to avoid sight obstructions at the intersection, and that further trimming is not possible
because vegetation is on private property. Continued maintenance is recommended as a short-term,
low cost measure to ensure that vegetation does not create a sight obstruction.
Relocate guardrail on the southeast corner. The existing guardrail is located close to the roadway and
may create a sight obstruction for drivers departing Williams Road. The guardrail should be relocated
further back from the roadway, possibly in conjunction with widening of the corner radius. This is a
short-term, low cost improvement.
Reapply pavement markings at the intersection. Existing markings are faded to the point of being
indistinguishable. Markings should be reapplied by the town as a short-term, low cost improvement.
Thermoplastic markings are recommended due to their longer lifespan. Arrow and ONLY markings
should be applied matching the lane use sign on Williams Road, and it was suggested that “STOP”
word markings be added to the stop lines on both side streets.
Replace existing “Dangerous Intersection” warning signage with W2-1
Intersection Warning signs on Route 101. It was suggested that the existing
signs are not effective in reducing speeds or changing driver behavior for
drivers on Route 101. It was also noted that the sign facing westbound
traffic is leaning away from the roadway, reducing its effectiveness. It is
recommended that these signs be replaced with standard Intersection
Warning signs with a fluorescent yellow background. It was also suggested
that these signs have supplemental plaques with the street name, consistent
with FHWA recommendations for low cost improvements at STOP
controlled intersections. After further discussion, it was recommended that
a supplemental speed plaque may be more effective in reducing driver
speeds. It is also recommended that signs be placed on both sides of the
roadway, which is also consistent with FHWA recommendations. This is a
short-term, low cost improvement.
Continue to enforce the 35 mph speed limit on Route 101. The Town should continue enforcement in
this area as a short-term, ongoing improvement, the cost of which is reduced enforcement elsewhere
in the Town.
Replace speed limit signs. Existing speed limit signs appear to be older signs and are likely not
reflective at night. Signs immediately adjacent to the intersection should be replaced in kind. This is a
short-term, low cost improvement.
Increase the southeast corner radius. This improvement requires further study to determine the
amount of widening necessary to eliminate encroachment from larger vehicles including school
buses. This is a short-term, low cost improvement, provided that there is adequate right of way
beyond the existing guardrail and no grading work is needed.

Warning signage alerting drivers to solar glare was discussed, but is not recommended at this time.
Solar glare warning signage such as that found on Route 2 warns drivers in advance of solar glare
conditions, but is not likely to help at an intersection where solar glare contributes to other visibility
concerns. It was also noted that existing signage warning of the dangerous intersection does not result
in a change in driver behavior, suggesting that additional text based warning signage may be
ineffective and simply create sign clutter.
Widen Route 101 to accommodate wide shoulders. This would improve overall visibility for all
approaching vehicles, give vehicles a slightly bigger recovery zone and improve the turning radius
from side streets. There is available right-of-way on the north side of Route 101 and may require the
widened road to be shifted to the north to avoid and/or limit property acquisition. It should be noted
that speed may become more of an issue with a widened roadway, and increased enforcement may be
needed. This is a long-term, high cost improvement.
Implement a driver awareness program at the high school. The program would educate high school
students about exhibiting safe habits at the intersection and can include education relating to any
potential future improvements. This is a short-term, low cost improvement.
Summary of Road Safety Audit
Table 3 summarizes potential recommendations discussed by the audit team. The recommendations are
categorized based on the potential safety payoff, as well as by time frame and cost. The safety payoff is a
qualitative judgment of the effectiveness of the potential safety improvements. Each recommendation has
a responsibility assigned to it stating whether MassDOT or the Town of Ashburnham would be
responsible for implementing the recommended improvement. All improvements have an order of
magnitude cost assigned.
