Background
The Road Safety Audit (RSA) focused on the segment of Route 16 in Douglas, Massachusetts, from the
Webster Town Line to the Main Street Intersection. The segment of Route 16 experienced 49 crashes
from 2010-2014, including three fatal and two incapacitating injury crashes. The Massachusetts
Department of Transportation (MassDOT) has determined that the Town of Douglas would be eligible to
receive funding for resurfacing and other quality improvements for Route 16 under the High Risk Rural
Roads (HRRR) program of the Highway Safety Improvement Program (HSIP) if a RSA were conducted
and the proposed design incorporated the safety improvements identified in the RSA. The HRRR
program requires a roadway to be classified as a collector or local roadway in a rural area on which the
crash rate for injury crashes or fatal crashes is higher than the statewide average. The RSA study area is
illustrated in Figure 1.
In general, the RSA is intended to identify potential safety improvements that can be evaluated and
included as part of current and/or future design efforts for resurfacing/reconstruction. The short-term,
low-cost potential improvements could be considered by the responsible agency for implementation prior
to improvements proposed under MassDOT Project No. 608168, as appropriate.
The MassDOT Project No. 608168 for Webster Street (Route 16) Safety Enhancements is scheduled to
complete the design phase and be ready for bid and construction in FY 2017 (October 1, 2016).

Prior to the RSA, in order to begin assessing possible safety issues, the team reviewed collision diagrams
and a crash detail summary based on crash records supplied by the Douglas Police Department for the
corridor. Appendix C provides the detailed crash data for the study area. For the 5 year period between
January 2010 and December 2014, there were 49 crashes reported along Route 16 between the Webster
town line and the Route 96 intersection. This included 3 fatal injury crashes, 2 incapacitating injuries, 7
minor injuries, and 37 property damage only crashes. The majority of the crashes were single vehicle
crashes (73%) which generally involved loss of control of the vehicle and striking a fixed roadside object.
In particular, 26% of the crashes involved collisions with roadside utility poles. A noticeably high
percentage of the crashes (60%) within the study period occurred during a four month winter period. Of
these crashes, 18 occurred while the roadway conditions were either snowy or icy. Finally, a large
percentage of the corridor crashes (43%) occurred during nighttime hours potentially due to limited
roadway delineation and street lighting.
Additionally, the project team performed a drive through of the project area to familiarize ourselves with
and video document the roadway for presentation at the RSA and reviewed previous studies, master plans,
and development plans along the corridor.

Project Location and Description
The RSA area is located within the Town of Douglas, MA along an approximate 4 mile segment of Route
16 (Webster Street). The segment of roadway runs east/west from the Webster town line to the intersection
of Route 96 (Main Street). The roadway is under Town of Douglas jurisdiction and is classified as an
Urban Minor Arterial/Rural Major Collector and has a posted speed limit of 45 mph throughout the
segment. Average Annual Daily Traffic (AADT) volumes for the corridor are approximately 5,700 to
6,000 vehicles per day with 7% to 8% trucks based on 2014 count data provided by the Central
Massachusetts Regional Planning Commission. This roadway serves as the primary connection between
downtown Webster & I-395 to the west and Douglas Center & Route 146 to the east. Within the study
area, the roadway consists of one (12’) travel way in each direction with varied paved and unpaved
shoulders (0-2’ paved, 2’+ - 12’+ unpaved and also a few trail head parking spots and bus turnarounds).
This stretch of roadway is largely rural due to the adjacent Douglas State Forest and consists of only a few
minor intersections (described below) and driveways to residential properties mainly on the east end of the
corridor. As the roadway alignment consists of several long tangent segments with minimal defined access
points, passing is permitted in several locations.
During the RSA mention was made that due to the high elevation of the road situated within the Douglas
State Forest, it is the road crews first assignment to sand/salt/plow Webster Street during winter weather
events.
There are two intersections along this stretch of Route 16 that were also evaluated:
Route 16 (Webster Street) at Cedar Street is a four-way unsignalized intersection. Cedar Street, which
is a local roadway under Town of Douglas jurisdiction, crosses Route 16 at an approximate 45 degree angle
and is stop controlled. Dedicated turning lanes are not provided on any of the approaches. An aerial of this
intersection in shown in Figure 2.
Route 16 (Webster Street) at Route 96 (Main Street) is a three-way intersection with a flashing beacon.
Route 96 (Main Street), which is also an Urban Minor Arterial/Rural Major Collector under Town of
Douglas jurisdiction, moves freely while Webster Street is stop controlled. While dedicated turn lanes are
not provided, an unconventional shared EB right/NB slip lane allows some traffic to bypass the main
intersection. The large expanse of pavement and unclear traffic control create driver confusion and errors.
An aerial of this intersection is shown in Figure 3.

Audit Observations and Potential Safety
Enhancements
During the pre-audit video walkthrough and the field
investigation performed on Monday, May 18, 2015; the
RSA team identified several safety issues along the
corridor and at intersections including travel speed,
roadway geometry, surface drainage, signage, lighting,
sight distance, and pavement condition.
Route 16 (Corridor-Wide)
Observations:
Travel Speeds
The posted speed limit throughout the Webster Street
corridor is 45 mph. Speed data that was collected with
RSA Team performs field investigation on
the traffic counts indicated that the average running speed
May 18, 2015.
at the Webster Town line was approximately 45 mph with
an 85% speed of 49 mph, while just east of the Main
Street intersection the average speed was 40 mph with an 85% speed of 44 mph.
However, the local public safety officials believe that speeding is a significant safety issue within the corridor. It is believed that the speed data is misleading, as the data locations are on either end of the project
and do not cover the central “tangent” portion of the roadway. The straight roadway geometry and minimal
driveways & intersections through the Douglas Town Forest section are believed to afford drivers the
opportunity to travel at speeds significantly above the posted speed limit. The crash data supports this
assumption as 17 of the 49 crashes cited motorists driving erratically or too fast for conditions.
The Douglas Police Department indicated that some level of enforcement is done on this stretch of roadway
each day during the AM or PM peak periods and that a large number of the citations in Town are given in this location.
With existing pavement markings passing is allowed in several locations throughout the corridor and
there are several crashes that have resulted from these maneuvers over the 5-year period.

Roadway Geometry
The roadway alignment for Route 16 between the
town line and Main Street generally consists of
long tangents connected by fairly flat curvature
(3000’ R or larger). However as the roadway
approaches Main Street and the residential
density increases, a few of the curves have a
significantly sharper radius (1500’ or less)
without proper warning and appear to be in poor
relationship with the vertical curve (i.e. a
horizontal curve located beyond a vertical crest
curve. This relationship between the horizontal
and vertical geometrics is undesirable as the
“crest” blocks the drivers line of sight to see the
horizontal
curve ahead. Similarly, the vertical
Turned-down guardrail terminals increase
profile of the roadway throughout the Douglas
risk for serious injury if impacted.
State Forest section is generally flat with a
constant downgrade from west to east which
would tend to elevate travel speeds for eastbound traffic. After the Cedar
Street intersection, the profile consist of shorter vertical curves which limit
sight distance of approaching vehicles, intersections, and horizontal curves.
Of particular concern is the utility pole adjacent to house #68. Due to
roadway geometry the pole has been struck many times.
The pavement section on Route 16 consists of one 12’ travel lane in each direction and generally 6” to 2’ of
paved shoulder. A varying width gravel shoulder, from 0’ up to 8’ or 10’, limit driver expectancy.
The roadside along Route 16 consists of numerous obstructions within the 18’-20’ clear zone. The clear
zone is an area beyond the travelled way paint marking, measured perpendicular, to establish a zone free
from obstruction to the driver. The clear zone for a roadway with a 45 mph speed limit and approximately
6,000 vpd should be 18’ to 20’ from the edge of travelway, which is generally not provided. Utility poles
are located on one side of the road or the other throughout the corridor and are generally located within 4’-6’
of the edge of pavement. The tree line, while further back than the utility poles, are is still located within the
clear zone. Additionally, there are several locations where large glacial boulders or rock faces are
reachable by vehicles. This is indicative of the crash data as 26 of the 49 crashes or 53% involved a single
vehicle and a fixed object along the roadside (13 of these crashes included utility poles). Guardrail is
provided in numerous locations to protect steep side slopes, water, and other hazards. However, the
majority of the guardrail terminals are simply turned-down type terminals rather than energy absorbing
terminals. Turned-down terminals may not meet current state/federal roadside safety standards based on the
85th percentile speed which is not yet determined.
Finally, there are a couple of gravel areas used as school bus turn-arounds for the Town’s of Douglas and
Webster located along the corridor. These locations are simply gravel bump-outs which allow the bus to
pull out of traffic, but do not allow the bus to complete its maneuver without blocking traffic. Advanced
signage for these bus turnarounds are provided, however, safety concerns have been raised in the past.
Drainage
Although effective capture of stormwater in roadside ditches and closed system pipes and structures is not
known to be a concern, the RSA team noted that the heaved and rutted pavement surface along Route 16
allows water and ice to become trapped on the paved roadway surface, which can lead to hydro-planning
Page 8
Road Safety Audit—Route 16 (Webster Street) Corridor, Douglas
Prepared by Hoyle, Tanner & Associates, Inc.
and ultimately result in vehicles losing control.
Signage
The RSA team identified that there is limited and
ineffective signage throughout the corridor. Although it
was not measured, it is believed that the corridor signing
may not meet current retroreflective requirements, which
is of particular concern for the warning signs. The
posted speed limit signs are combined with a “Radar
Enforced” message on the standard size sign which
decreases the text size of the speed limit numerals and
reduces visibility. The team also noted that curve
warning signage is not provided along the corridor for
any of the sharper horizontal curves. There have been
several crashes related to the roadway curvature where
vehicles have lost control and struck fixed objects
resulting in incapacitating or fatal injuries.
Delineation
Roadway departures along the existing
horizontal curve at #68 Webster Street have
resulted in serious and fatal injuries.
Route 16 contains limited roadside delineation throughout the corridor. These measures which include
retroreflective pavement markings, post mounted delineators, and guardrail delineators allow motorists to
identify the edge of the roadway. They are especially useful for identifying roadway curvature and provided
added visibility during nighttime operation and inclement weather. This is a particular concern for Route
16 as 43% of crashes occurred during nighttime hours, while 32% of crashes were during weather events.
The double yellow roadway centerline along Route 16 has been recently repainted, however, the white edge
lines remain faded. Retroreflective roadside reflectors are not provided within the project limits. Guardrail
delineator use is inconsistent and does little to help define the edge of the roadway. Additionally, the use of
delineators on roadside utility poles is inconsistent.
Lighting
The RSA team identified that there is very little lighting along the Route 16 corridor and the Douglas State
Forest section is particularly dark during nighttime hours. Utility pole lighting is provided at the project
intersections and at a few of the sharper curve locations, however, the team believes it to be ineffective for
providing adequate lighting and awareness of the roadway condition.
Pavement Condition
A major concern for the Town of Douglas is the condition of the pavement surface throughout the corridor.
The Town’s limited resources for roadway improvements and the large volume of trucks which utilize the
corridor has led to a pavement surface that has become significantly cracked, heaved, and rutted;
especially during the winter months when 60% of the crashes occur.
The uneven pavement surface allows stormwater runoff to pond on the roadway and makes it significantly
more difficult to clear the roadway during winter weather conditions. In addition, the Town has noted that
the roadway is a regional cold spot in Town that freezes prior to other adjacent roadways due to the rise in
elevation through this segment and that the substantial tree cover limits sun exposure and increases the
duration of ice on the pavement.
Page 9
Road Safety Audit—Route 16 (Webster Street) Corridor, Douglas
Prepared by Hoyle, Tanner & Associates, Inc.
This deteriorated pavement not only increases the likelihood of hydroplaning and wheel slippage during wet
& icy conditions, but the significant bumps may also increase the likelihood of loss of control during dry
periods as well. The crash data support this theory as 50% of crashes occurred when there was precipitation
on the roadway. The Town also noted that the road crown has deteriorated over the years.
Wildlife Collisions
Due to its rural nature, the Route 16 corridor also experiences a significant amount of collisions with
wildlife. During the 5-year reporting period, seven collisions involving deer were reported. Town Officials
indicated that this is a larger concern along the eastern residential end of the project where animals may be
feeding in resident’s yards.
Bicycle Accommodations and Signs
Due to statements made by Town officials, accommodations for cyclists, mountain bikes and pedestrians
that travel along and cross the corridor should be made. The lack of bicycle facilities was stated. Also,
pedestrians tend to cross in the areas of tail heads. Advance signage and trail designations would help alert
drivers of upcoming pull-offs and possible pedestrians.
Impaired Drivers
The Police mentioned that OUI’s have been an issue in the past with drivers returning from bars in Webster
in the evening. Increased enforcement was mentioned as a method to address the issue.
Potential Safety Enhancements:
1. Consider providing MUTCD compliant speed limit signage with standard numeral sizes and
supplemental “Radar Enforced” plaques to aid in motorist identification of the posted speed limit.
2. If available, consider using both permanent and temporary speed display signs to alert motorists to
their current speed in comparison to the posted speed. In rural corridors with long straight sections
like Route 16, perception of speed can sometimes be challenging.
3. Remove passing zones along the corridor help reduce overly aggressive driving. Town Officials
believed the passing zones were unnecessary due the relatively short corridor length between
Webster and Douglas. If passing zones are to remain; length, sight distance, and signage to meet
adequate design criteria should be evaluated.
4. Consider reducing travelway lane width to 11’, particularly in the denser eastern section of the
roadway, to attempt to reduce vehicle speeds “traffic calming measure” and alert motorists to the
more thickly settled residential area.
5. Provide high friction surface course in sharper horizontal curvature to reduce roadway departure
particularly at the #68 house. Consider maintenance issues associated with this.
6. Provide wider paved shoulders (5’ for bicyclist accommodation) and a consistent gravel shoulder.
This will allow additional recovery space for vehicles prior to departing the roadway and will allow
bicyclists and pedestrians to keep out of the traveled way. Consider utilizing a Safety Edge, as
Page 10
Road Safety Audit—Route 16 (Webster Street) Corridor, Douglas
Prepared by Hoyle, Tanner & Associates, Inc.
defined by FHWA to, along the edge of the shoulder to reduce tire scrubbing which causes vehicles
to lose control as they depart the paved surface.
7. Work with utility companies to shift poles out to the ROW (particularly west of Cedar Street where
the ROW is wide and at house #68) to provide a larger clear zone for errant vehicles. Most
importantly in the case of the pole at house #68.
8. Consider clearing trees out to the limits of the ROW or to the edge of the appropriate clear zone
width of 18’ to 20’ feet from the traveled way for Route 16 according to AASHTO Roadside Design
Guide standards to reduce the risk of vehicle fixed object collisions.
9. Consider replacing turn-down guardrail terminals with Energy Absorbing Guardrail Terminals
(EAGRT) to limit the potential for injury if guardrails are struck.
10. Expand and pave bus turn-arounds to allow completion of maneuver using available ROW. Ensure
that these locations are intended to be used by bus companies into the future.
11. Resurface roadway to provide an even pavement surface which will eliminate ponding on roadway
and reduce out of control crashes due to hydroplaning, wheel slippage, and bumps. In the short
term, consider tree trimming to allow additional sunlight to penetrate the corridor.
12. Consider providing Intelligent Transportation System (ITS) solution such as dynamic
signing/flashers or roadway sensors that will allow Town Officials to be alerted and inform
motorists to slippery road conditions.
13. Provide curve warning signage and advisory speed plaques, as needed, to alert motorists to
unexpected “sharp” curvature and reduce the potential for roadway departure crashes.
14. Replace aged signage with new signs meeting current retroreflective standards to ensure visibility
during nighttime and inclement weather.
15. Restripe roadway edge lines with retroreflective paint markings to help motorists identify the edge
of the traveled way.
16. Provide retroreflective post mounted delineators along the corridor and chevrons on the curves, to
help motorists identify the roadway horizontal geometry. Additionally, provide retroreflective
markers on utility poles and other roadside hazards to increase visibility of these obstructions.
17. Provide deer crossing signage with supplemental mileage plaques (i.e. Next XX miles) to alert
motorists to potential animals in the roadway.
18. Adding street lighting west of the Cedar Street intersection.

Route 16 at Cedar Street
Observations:
Skew Angle and Vertical Geometry at Cedar
Street limit intersection sign distance.
Intersection Geometry
Cedar Street forms a four-way intersection with
Route 16 and has a skew angle of approximately
45 degrees and requires Cedar Street vehicles
(especially southbound) pull out into the Route 16
travel lane and look over their right shoulder to see
oncoming traffic. The resulting geometry from the
skew also provides tight pavement radii on the
acute angle side of the intersection and large
sweeping radii on the opposite side. This allows
for vehicles making right hand turns onto to Cedar
Street to do so at high rates of speed, while
vehicles making right hand turns out of Cedar
Street (especially large vehicles) must travel slowly
to remain on the paved surface. Additionally, the
southbound approach for Cedar Street is an uphill
grade at Route 16. This grade combined with a
vertical crest curve located just to the east of the
intersection make it difficult to see approaching
westbound vehicles.
While the crash data for the most recent five-year period does not indicate a significant amount of crashes
in this location, the Douglas Police Department indicates that there is a history of approximately 1 crash
per year over the last 20 years.
Sight Distance
In addition to the sight distance issues created by the skew angle and roadway profiles, the sight lines are
further obstructed by trees, fences, guardrails, and utility poles that are located in close proximity to the
edges of pavement. Also the southbound stop bar location is quite a ways back from Route 16 and requires
vehicles to advance beyond it to get a clear view.
Signage
Intersection warning signage is provided on the approaches to Cedar Street, however, it does not stand out
and is easily overlooked due to its placement behind the guardrail amongst the trees and utility poles
obscures. In addition, these signs may not meet current retroreflective standards.
Drainage Issues
The catch basin grate and frame located in the southeast corner of the intersection is a continuous issue. It
appears that larger vehicles making right turns onto Webster Street have and continue to cause damage to
the structure. The Town struggles to keep it in good working order.
Pedestrians
Pedestrians cross the intersection to enter the State Forest from Cedar Street and no cross walk is provided.
Page 12
Road Safety Audit—Route 16 (Webster Street) Corridor, Douglas
Prepared by Hoyle, Tanner & Associates, Inc.
Potential Safety Enhancements:
1. Replace intersection warning signage to meet current retroreflective standard and confirm proper
advanced warning distance for sign placement. Additionally, consider utilizing an oversized or
flashing sign to increase visibility and alert motorists to this unanticipated intersection.
2. Consider installing a four-way flashing signal which would improve visibility of the Cedar Street
intersection and alert motorists to the potential for conflicting traffic. The signal would flash yellow
for Route 16 which operates freely, and red for Cedar Street which is under stop control.
3. Shift stop bar location on Cedar Street southbound approach to appropriate offset from Route 16
edge of travel way.
4. Consider removing/relocating trees, guardrail, fences, and utility poles, on intersection corners, as
feasible, to improve sight lines for vehicles approaching and departing the intersection.
5. Consider installing additional street lighting to improve motorist recognition of the intersection and
the potential for conflicting vehicular and pedestrian movements.
6. Lower frame and grate and provide paved apron for catch basins on southeast quadrant to reduce
impacts and improve drainage capture with large turning vehicles within a built shoulder layout
capable of accommodating “off-tracking”.
7. Consider adding a cross walk with proper advanced signage.
8. Intersection reconstruction with approach realignment and profile improvements
Route 16 at Route 96 (Main Street)
Observations:
Intersection Geometry
Unconventional Intersection Geometry at
Main Street leads to driver confusion and an
increased crash rate.
Route 16 forms a three-way intersection with
Route 96 (Main Street) adjacent to the Old
Douglas Center. Route 16 is under stop control
while Route 96 operates freely. Previous
iterations of this intersection provided an
eastbound right turn/ northbound left turn slip
ramp separated by a raised traffic island that
formed a unconventional Y-intersection. In
recent years due to large vehicles driving over
the curb and hitting a Town fire hydrant, the
island was removed and replaced with pavement
and a traffic barrel with a stop sign mounted to
it. This large expanse of pavement results in
driver confusion as to where turning maneuvers
are supposed to be performed. Northbound left
turning vehicles either use the former slip lane
Page 13
Road Safety Audit—Route 16 (Webster Street) Corridor, Douglas
Prepared by Hoyle, Tanner & Associates, Inc.
(which places them adjacent to the eastbound queued vehicles) or utilize the actual T-intersection. Similar
maneuvers are made by Eastbound right turning traffic. Southbound right turning traffic must also negotiate
a sharp corner radii which reduces operating speeds and sometimes results in vehicles leaving the pavement.
The traffic volumes combined with poor intersection geometry allows for a queue of 5 to 6 vehicles to form
during the peak hour. Additionally, a vertical crest curve located approximately 350’ west of the eastbound
stop bar reduces awareness of the intersection and the drivers available stopping sight distance.
Although the crash data (and local Safety Official memory) does not reveal any severe crashes at this
location, several incidents of vehicles approaching this intersection and rear-ending stopped or turning
vehicles have occurred over the 5-year study period. The crash data for this intersection was not included
in the analysis as it is beyond the extents of the corridor.
Sight Distance
As previously noted, the sight distance approaching the Route 96 intersection is compromised by the vertical
geometry of the roadway. The result is that vehicles do not always recognize the need to reduce speed and
are often required to come to more abrupt stops than anticipated.
Signage
“Stop-ahead” signage is provided for the Route 16 approach to the Route 96 intersection. In addition, a
post-mounted alternating yellow flashing beacon is provided to alert motorist of the condition. However,
this infrastructure is located over 1,200 linear feet from the intersection which greatly exceeds the advanced
warning distance for the posted speed limit with this condition. This deviates from drive expectancy and
does not provide the motorist with an accurate estimate of how soon the required stopping condition will
occur. Additionally as the flashing beacon is not located with the “Stop Ahead” sign, it is not clearly
apparent what condition the beacon is attempting to alert motorist to.
Potential Safety Enhancements:
1. Consider realigning intersection through pavement removal and re-striping to eliminate the slip lane
and form a more conventional “tee” intersection layout. This should help to eliminate driver
confusion, reduce intersection queue, and reduce rear-end collisions
2. Consider reducing speed limit below 45 mph in advance of intersection and alerting motorists to
“Congested District” utilizing signage. Upon inspection of the regulatory speed limit it appears that
the following exists: Begin Webster Town Line 45 MPH for 3.97 miles eastbound; then 20 MPH
for 0.16 eastbound to the intersection. It appears that there is a speed reduction prior to the
intersection that is not signed. Also, based on the great reduction it would require advanced reduced
speed limit signs along the intersection approach. This should help to notify motorists that they
have left the more rural portions of the corridor and roadway conditions are changing.
3. Revise “Stop Ahead” sign location and combine with flashing beacon to improve driver expectancy
of the approaching intersection in conformance with MUTCD requirements.

Summary of Road Safety Audit
The RSA team identified several potential safety enhancements for the Corridor-wide safety issues that were
identified, as well as the specific issues at the Cedar Street and Main Street intersections. Table 2
summarizes the solutions that were discussed and identifies the location, safety issue, potential
enhancement, safety payoff, time frame, relative cost, and the agency responsible for the enhancement. The
summary table allows for a quick comparison of the potential solutions and forms the basis of a cost/benefit
analysis.
The safety payoff estimates are based on published Crashed Reduction Factors (CRF) for similar projects, if
available, and engineering judgment. These have been categorized as low (<30%), medium (31% to 70%),
and high (>71%). The time frame for potential enhancements were categorized as short-term (<1 year),
mid-term (1 to 3 years), and long-term (>3 years). As HSIP funding through the HRRR program is expected
to be available for construction along the corridor in FY 2017 (October 1, 2016), potential enhancements
that would may be able to be accomplished as part of this project but would traditionally be considered long­
term improvement were placed in the mid-term category. Short-term solutions could either be constructed
as part of this larger construction effort or installed in advance by the responsible agency using other
funding sources. The cost for potential enhancements have been broken up into Low (<$10,000), Medium
($10,001 to $50,000), and High (>$50,001).
