BackgroundThe intersection of Bedford Street (Route 18) and Randolph Street/North Avenue (Route 139) in the Town of Abington, Massachusetts is listed as #24 according to the Massachusetts Department of Transportation’s (MassDOT) 2006-2008 Statewide Top 200 Intersection Crash List. As such, the MassDOT conducted a Road Safety Audit (RSA) to identify the safety issues and potential safety enhancements.
Route 18 between Highland Avenue in Weymouth and Route 139 in Abington is currently in the preliminary design phase for a widening and reconstruction project (#601630), with construction anticipated to begin in Spring 2013. The RSA is intended to identify potential safety improvements that can either be evaluated and included as part of the current design process or considered as part of future reconstruction efforts at the intersection. The short-term, low-cost potential improvements could be considered by the responsible agency for implementation prior to reconstruction, as appropriate.
Project Data The audit team conducted an RSA for the intersection of Route 18 and Route 139 on Thursday, July 14, 2011. 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.

Project Location Description and Crash Summary The intersection of Bedford Street (Route 18) and Randolph Street/North Avenue (Route 139) is located in the Town of Abington, as shown in the aerial image in Figure 1. The intersection is located approximately four miles south of Route 3 (Exit 16). Commercial uses are located on all four corner of the intersection and the Abington Fire Department is located approximately 900 feet north of the intersection on Route 18.
Route 18 at Route 139 is a four-way signalized intersection. The Bedford Street (Route 18) eastbound approach consists of one shared left-turn/through lane, one through lane, and one dedicated right-turn lane. The North Avenue (Route 139) westbound approach consists of one shared left-turn/through lane and one shared through/right-turn lane. Wales Street intersects North Avenue from the northeast at an acute angle approximately 100 feet east of Route 18; Wales Street operates under yield control. The Bedford Street (Route 18) northbound and southbound approaches each consist of an exclusive left-turn lane, one through lane, and one shared through/right turn lane.
The intersection forms the junction of the following roadways, which are categorized according to MassDOT Office of Transportation Planning functional classifications:
Bedford Street (Route 18) is an urban principal arterial and falls under MassDOT jurisdiction. Bedford Street is a north–south roadway and is dedicated as Route 18. Within the vicinity of the intersection, Route 18 generally consists of one travel lane in each direction. The speed limit along Route 18 is 35 miles per hour (mph) per the speed regulations.
Randolph Street (Route 139) is an urban principal arterial and falls under Town jurisdiction. Randolph Street is an east–west roadway. Within the vicinity of the intersection, Randolph Street consists of one travel lane in each direction. The speed limit along Randolph Street is 30 mph per the speed regulations.
North Avenue (Route 139) is an urban minor arterial and falls under Town jurisdiction. North Avenue an east–west roadway. Within the vicinity of the intersection, North Avenue consists of one travel lane in each direction. The speed limit along North Avenue is 30 mph per the speed regulations.
Wales Street is a local roadway and falls under Town jurisdiction. Wales Street is an east–west roadway. Within the study area, Wales Street consists of 1 travel lane in each direction.
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 Abington Police Department and the Registry of Motor Vehicles. From January 2008 through December 2010, 79 crashes were reported at the intersection. Of the 79 crashes, a majority were angle type crashes (39 or approximately 49%), rear-end (20 or approximately 26%), and sideswipe same direction crashes (6 or approximately 8%). Crashes generally occurred on dry pavement (48, or nearly 61%) in clear weather conditions (41, or nearly 52%) and under good lighting conditions (daylight or lighted roadway) (65 or 82%). Approximately 24% of the crashes (or 19) occurred on wet or snow covered pavement. Appendix C provides the detailed crash data for the intersection. Speed regulations and traffic volume data are presented in Appendix D.

Road Safety Audit Observations and Potential Enhancements Based on field observations on Thursday, July 14, 2011, the RSA team determined that the intersection of Route 18 at Route 139 has the following issues that affect safety:
� Traffic signal indications, phasing, and clearance intervals; � Access management; � Pavement markings; � Signage;� Utility pole placement; and � Limited pedestrian accessibility.
The following sections describe in more detail the safety issues and enhancements determined during the RSA. Several of these issues require further study and engineering judgment to determine the feasibility of implementing enhancements to address them.
Safety Issue #1. Traffic Signal Indications, Phasing, and Clearance Intervals
Observations: The Route 139 eastbound and westbound approaches currently allow for permissive left turns only; protected left turns are not provided. RSA team members commented that it can be difficult for motorists to find an acceptable gap in the passing traffic stream to make a left-turn and noted that motorists do not have a dedicated left-turn lane.
According to the crash records, 12 of the crashes (or approximately 15%) involved motorists that failed to stop at the red light. Of these 12 crashes, 10 (or 83%) involved vehicles traveling along either the Route 139 eastbound or westbound approach. During field observations, the RSA team noted that vehicles making left-turns at the Route 139 eastbound and westbound approaches often queue in the middle of the intersection while waiting to find an acceptable gap in the passing traffic stream. Many of these
Left-turns from Route 139 eastbound.

Page 6
left-turning vehicles were observed traveling through the intersection during the red phase, which may have contributed to the crash experience at the intersection.
According to traffic volume data collected by MassDOT at the intersection during April 2011, left-turns at the Route 139 eastbound approach reach between approximately 100 and 120 vehicles per hour during the morning and evening peak periods– slightly above the 100 left-turns per hour minimum requirement for an exclusive left-turn lane per the MassDOT 2006 Project Development & Design Guide. Meanwhile, left turns at the Route 139 westbound approach are generally below the 100 left-turns per hour threshold during the peak periods.
Lastly, the RSA team also noted that some of the light emitting diodes (LED’s) are not working on several of the traffic signal indications making them less visible.
Enhancements:1. Evaluate clearance intervals at all of the intersection approaches per Institute of
Transportation Engineers (ITE) standards (short-term).
2. Consider the appropriateness of providing an advance left turn phase, and associated signal equipment upgrades, for the Route 139 eastbound approach to allow for a protected left-turn in addition to the permissive left-turn (short-term).
3. Review the safety and operational benefits/impacts of adding an exclusive left-turn lane for the Route 139 eastbound approach.
4. Maintain LED traffic signal indications to ensure visibility.

Safety Issue #2. Access Management
Observations: The intersection of Route 18 at Route 139 currently has commercial uses located on each of the four corners of the intersection resulting in numerous curb cuts in the vicinity of the intersection. Of the 79 crashes reported at the intersection, 32 crashes (or nearly 41%) occurred at commercial driveways adjacent to the intersection. The RSA team noted the following with respect to access management at the Mobil and Sunoco gas station driveways:
Mobil Gas Station
The largest concentration of the crashes at the commercial driveways occurred at the intersection of the Mobil gas station driveway and Randolph Street (Route 139) with nine crashes reported between January 2008 and December 2010. Of these nine crashes, seven were angle type crashes involving eastbound through traffic and vehicles making left-turns out of the Mobil driveway onto Route 139.
Route 139 eastbound consists of one travel lane to the west of the intersection and widens to three lanes in the vicinity of the Mobil driveway to allow for one shared left-turn/through lane, one through lane, and an exclusive right-turn lane at the intersection with Route 18. Thus, motorists making the left turn out of the Mobil driveway onto Route 139 need to cross three travel lanes. According to RSA team members, a motorist traveling along Route 139 eastbound may stop to allow a vehicle to make the left-turn out of the Mobil driveway; however, a second or third vehicle traveling in one of the other eastbound lanes may not expect, or be able to perceive and react to, a left-turning vehicle exiting left from the driveway. Likewise, a motorist making a left-turn out of the Mobil driveway onto Route 139 may not be able to see vehicles traveling in all three of the eastbound lanes if a first vehicle stops to allow them to make the turn.

Sunoco Gas Station
The Sunoco gas station, located on the southeast corner of the intersection, is constructed at a slightly higher elevation than Route 18 resulting in a fairly steep vertical grade change at the driveway accessing the site. The RSA team noted that the grade change at the driveways result in vehicles entering the gas station at a slower rate of speed in an effort to avoid scraping the bottom of their vehicle. Motorists, unfamiliar with the location, may not expect the need to slow down at the
driveway apron when trying to judge an adequate gap in the Route 18 northbound traffic stream (three lanes) to safely make a left-turn.
Enhancements: 1. The audit team was in agreement that this location warrants serious consideration of
restricting left-turns from the Mobil Driveway onto Randolph Street (Route 139).
2. Consider the safety benefits of restricting Route 18 southbound left-turns into the Sunoco Driveway if crash experience worsens/continues. Also consider any resulting impacts on heavy vehicle access (e.g., fuel deliveries).

Safety Issue #3. Pavement Markings and Signage
Observations: During field observations the RSA team noted that there is a crest vertical curve in the alignment of Route 18 just north of the intersection in the vicinity of where the roadway widens from one to three travel lanes in the southbound direction to allow for a turning lane and an additional turning lane at the intersection. As a result, the vertical curve reduces the visibility of the southbound vehicles queued for a red light.
An RSA team member also noted that the lane lines do not extend past the vertical curve. Thus, motorists unfamiliar with the intersection may not anticipate the need to change lanes, or that they are arriving at an intersection approach until they have already arrived. According to the crash records, there were eight rear-end crashes and four sideswipe (same direction) crashes reported involving vehicles at the Route 18 southbound approach. Unclear lane use designations may have contributed to these crashes. However, during field observations an RSA team member did note that a mandatory movement lane control sign indicating “Left Lane Must Turn Left” (R3-7) was posted. After the audit, a review of the original design plan shows a dotted white lane line (DWLL) proposed to delineate the left-turn only lane.
Lastly, each of the intersection departures has two receiving lanes that taper to one travel lane. The RSA team noted that the pavement markings in each of the merge areas are either worn or missing. In addition, no supplemental signage is provided warning motorists of the merge such as Lane Ends symbol signage (W4-2) and/or Right Lane Ends (W9-1) or Lane Ends Merge Left (W9-2).
Crest vertical curve limits sight lines of Route 18 southbound approach and lane designations.

Enhancements:1. Add a DWLL, as originally designed, to provide delineation of the Route 18 southbound
left-turn lane.
2. Evaluate the feasibility of installing an Advance Intersection Lane Control (R3-8) sign along Route18 southbound to provide additional lane use information.
3. Evaluate the appropriateness/feasibility of installing broken white lane line pavement markings at each of the receiving lanes to delineate the two travel lanes.
4. Consider the appropriateness of installing warning signage (e.g., Lane Ends symbol signage (W4-2) and/or Right Lane Ends (W9-1) or Lane Ends Merge Left (W9-2)) at each of the receiving lanes to warn drivers of the lane reduction.

Safety Issue #4. Utility Pole Placement
Observations: The RSA team noted that the utility poles located on the northeast, northwest, and southeast corners of the intersection are positioned close to the curbline. According to the crash records, there was one crash reported involving a motorist that hit the utility located on the southeast corner of the intersection.
During field observations, the RSA team also noted that the wiring on the utility poles (across the intersection) partially inhibits the view of the signal indications in the Route 18 northbound and southbound direction.
Finally, the team noted that the presence of a utility pole and a traffic signal foundation on the northwest corner of the intersection significantly reduces the effective width of the sidewalk.
Enhancements: 1. Relocate utility poles at intersection further away from the edge of the roadway if there is
space within the right-of-way and where feasible. Consider the placement of the utility lines and poles with respect to the visibility of the traffic signal indications and the impact on the effective width of the sidewalk.

Safety Issue #5. Other General Observations
Observations: The RSA team also noted the following general observations with respect to overgrown vegetation and curb ramps:
Overgrown Vegetation – the RSA team noted that the visibility of the following signage was obstructed by overgrown vegetation:
� Route 18 guide signage along North Avenue (Route 139)/Wales Street westbound;
� Route 18 guide signage along Randolph Street (Route 139) eastbound; and
� Route 139 guide signage along Route 18 southbound.
Curb Ramps – an RSA team member noted that the curb ramps at the intersection do not have truncated dome tactile detectable warning surfaces.
Enhancements: 1. Maintain vegetation to improve visibility of guide signage along all approaches to the
intersection.
2. In stall truncated dome tactile detectable warning surfaces at all curb ramps per the MassDOT 2006 Project Development & Design Guide.
Overgrown vegetation obstructs view of guide signage at along the North Ave./Wales St. westbound approaches.

RecommendationsBased on its observations and discussions, the RSA team identified the issues and possible enhancements that could improve safety at the intersection of Bedford Street (Route 18) and Randolph Street/North Avenue (Route 139) in the Town of Abington, Massachusetts. Further design work or consideration may be necessary to determine the feasibility of making some of the improvements.
Short-term enhancements include:
� Evaluate and adjust clearance intervals as appropriate;
� Add protected left-turn phasing;
� Improve access management by adding turn restrictions;
� Extend and improve lane markings;
� Improve signing;
� Replace LEDs on traffic signal indication; and
� Trim vegetation overgrowth.
To enhance the safety of the intersection, the long-term enhancements are to:
� Widen the Route 139 eastbound approach for an exclusive left-turn lane; and
� Relocate utility poles.
Table 2 summarizes these 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).
The RSA is intended to identify potential safety improvements that can either be evaluated and included as part of the current design process for the Route 18 widening project or considered as part of future reconstruction efforts at the intersection. The short-term, low-cost potential improvements could be considered by the responsible agency for implementation prior to reconstruction, as appropriate.
