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, in consideration of all roadway users. Specific objectives of an RSA include, but are not limited to, minimizing the risk and severity of road crashes that may be affected by the existing or future roadway infrastructure at a specific location or nearby network, and improving the awareness of safe design practices which are likely to result in safety benefits based upon potential safety concerns. The Massachusetts Department of Transportation (MassDOT) has embraced the RSA program as a low cost opportunity to make significant safety improvements at any number of stages ranging from project development and planning through existing operation. A Road Safety Audit was scheduled for the intersection of Fall River Avenue (Route 114A) at County Street as part of the Luther’s Corner intersection improvements project (MassDOT Project Number 607392). The project limits on Route 114A extend approximately 600 feet north of County Street (to the Seekonk Congregational Church) and approximately 700 feet south (prior to Smith Street). On County Street, the project limits extend approximately 200 feet east (just beyond the Luther’s Corner Fire House) and 300 feet west of Route 114A to approximately the Rhode Island State Line. The intersection falls within the 2009- 2011 Highway Safety Improvement Program (HSIP) cluster and therefore is subject to a required RSA. The cluster contains 58 crashes, 11 of which resulted in injuries. The intersection of Fall River Avenue (Route 114A) at County Street falls on the 2011 Top 200 High Crash Locations Report1 ranked at number 141. Project Data A Road Safety Audit for the signalized intersection of Fall River Avenue (Route 114A) at County Street was held on Tuesday, July 22, 2014 at the Seekonk Town Hall in Seekonk, Massachusetts. Table 1 provides a list of the participating audit team members and their associated affiliation. As shown, the team represents a multidisciplinary group ranging from planning, engineering, and emergency response, to local, regional, and federal officials. Detailed crash history data from both MassDOT and the Town of Seekonk Police Department, and associated collision diagrams were reviewed prior to an in-field visit to the intersection. Additionally, traffic volume data, including Automatic Traffic Recorder (ATR) counts and Turning Movement Counts (TMC), was made available. These data are provided in the Appendix for reference. 1 2011 Top 200 Crash Locations Report (2009-2011), Massachusetts Department of Transportation, 2013.

Nicole Rogers Greenman-Pedersen, Inc. Project Location and Description The RSA focused on the signalized intersection of Fall River Avenue (Route 114A) at County Street within Luther’s Corner Village in Seekonk, Massachusetts, as shown in Figure 1. Functionally, Fall River Avenue (Route 114A) is a two lane road that runs in a north-south direction connecting Pawtucket Avenue (Route 114) to the north and Wampanoag Trail to the south in East Providence, Rhode Island. Fall River Avenue serves as a major route to the interstate highway system as it intersects with multiple arterials and collectors in East Providence, Seekonk, and Rehoboth. Exit 1 off of Interstate 195 (I-195) is located approximately ½- mile south of Luther’s Corner. Fall River Avenue (Route 114A) is functionally classified as an ‘Urban Minor Arterial’ within the project limits and is under Massachusetts Department of Transportation (MassDOT) jurisdiction. County Street is a two lane road that travels in an east-west direction providing a connection to Rhode Island roadways in the west and the Town of Rehoboth to the east. County Street is functionally classified as an ‘Urban Collector’ and is under local (Town of Seekonk) jurisdiction. There is no speed limit posted within the study area on Fall River Avenue (Route 114A), however it is posted at 35 miles per hour (mph) approximately ½-mile north of the intersection with County Street. This section of Fall River Avenue (Route 114A) is not zoned and therefore no speed regulation holds. The posted speed limit along Country Street is 30 mph which is consistent with the Special Speed Regulation for the roadway. The intersection of Fall River Avenue (Route 114A) and County Street serves as the foundation for the Luther’s Corner Village, a historic village with the potential to function as an attractive mixed-use village Page 2 Road Safety Audit—Luther’s Corner: Fall River Avenue (Route 114A) at County Street Prepared by Greenman-Pedersen, Inc. center. Land use within the study area varies between residential, mixed residential/commercial, commerial, restaurant and medical office. The intersection included in the audit is discussed in detail below. Fall River Avenue (Route 114A) at County Street Fall River Avenue (Route 114A) at County Street is a signalized 4-way intersection with Route 114A generally running north-south and County Street generally running east-west. The County Street eastbound approach consists of an 11 foot right turn lane with approximately 100 feet of storage and an 11 foot left-through lane. The current signal plan shows two approach lanes for the northbound approach on Fall River Avenue (Route 114A) however it is striped as a single multipurpose travel lane. Even though it is striped as single approach lane, the northbound approach functions as two lanes, with a dedicated left-turn lane on the inside and a through-right turn lane on the exterior.. The southbound approach on Route 114A is delineated as a single multipurpose (left-through-right) travel lane yet functions as two lanes at times when drivers use the breakdown lane to make a right turn onto County Street. The westbound approach on County Street operates as one general purpose lane, as marked. Crosswalks are provided across all approaches to the intersection, along with pedestrian push buttons and exclusive pedestrian phasing. Sidewalks are present along both sides of Fall River Avenue (Route 114A) and County Street. The concrete sidewalks along Route 114A vary in width from five to seven feet and are relatively new and in good condition. Mixed sidewalks of bituminous and concrete material are present along County Street, however are deteriorating and in need of replacement. Currently, handicap ramps do not meet MassDOT or ADA guidelines. There are no bicycle accommodations currently provided. This intersection is controlled by a fully- actuated uncoordinated traffic signal. The signal itself operates in three phases including an exclusive pedestrian phase that is serviced between the permitted mainline and side street phasing. The lack of protected left-turns can lead to higher delays for some movements. Figure 2 presents an aerial view of the intersection. Crash Analysis Crash data were provided by the Seekonk Police Department for the most recent complete three-year period (2011-2013) available. A total of 39 collisions were reported at the intersection according to the police crash records. Of these 39 crashes, 19 were rear-end collisions and 12 were angle collisions. The next most frequent crash-type were sideswipe crashes (seven reported), followed by one single vehicle crash with a fixed object. Of the total 39 crashes reported, 31 crashes (approximately 80 percent) had reported severity as being limited to property damage, with the remaining eight crashes reporting injury. No fatalities were reported within the Seekonk Police Department records. Page 3 Road Safety Audit—Luther’s Corner: Fall River Avenue (Route 114A) at County Street Prepared by Greenman-Pedersen, Inc. Furthermore, 19 additional collisions were reported within the project limits during the three-year period (2011-2013). The majority of the 19 collisions occurred at the various driveways to the Gulf Service Station, which is located on the north-western corner of the intersection of Fall River Avenue and County Street, and the Dunkin Donuts driveway located at 623 Fall River Avenue. The gas station has four driveways, two on Fall River Avenue, north of the intersection, and two on County Street, west of the intersection. The driveways on Fall River Avenue experienced seven collisions over the three-year study period. Of the total seven collisions, all resulted in property damage only, five were angle collisions and two were rear-end collisions. The driveways on County Street experienced two collisions over the threeyear study period. Both were angle collisions and resulted in property damage only. The driveway to Dunkin Donuts, located just north of the Gulf driveway on Fall River Avenue, experienced six collisions over the three-year study period. Three were angle collisions and three were rear-end collisions. All six collisions resulted in property damage only, 17 percent occurring during the commuter peak period and 33 percent occurring during wet/icy conditions. The driveway to the Hair’s to You salon located on the south-western corner of the intersection of Fall River Avenue and County Street experienced two collisions over the three-year study period. Both collisions were angle collisions resulting in property damage only, 50 percent occurring during wet/icy conditions and 50 percent occurring during the commuter peak period. One collision occurred outside of the Labonte Auto School located at 637 Fall River Avenue (directly south of the Hair’s to You salon) in which a driver leaving an on-street parking space sideswiped a vehicle traveling in the same direction. The collision resulted in property damage and occurred outside peak hours on dry pavement conditions. One collision occurred at the intersection of Fall River Avenue (Route 114A) and Jerry Lane over the three-year study period. The crash was an angle collision resulting in property damage only and occurring outside of peak hour on dry pavement conditions and may have been attributable to poor sight distance. It should be stated that a number of the collisions which occurred at these intersections were “courtesy crashes” in which a mainline vehicle stopped to allow a vehicle exiting one of the commercial driveways, but the exiting vehicle was subsequently struck by another mainline vehicle in the adjacent lane. Another common scenario is a mainline driver stopped in traffic to permit a vehicle in the opposite direction to turn left into a commercial driveway and subsequently is rear-ended due to sudden stoppage or inattention. In addition to the collision summary, crash occurrence also is compared to the volume of traffic through a particular intersection. Accordingly, the crash rate is compared to the district-wide average crash rate for a signalized intersection. An intersection crash rate is a measure of the frequency of collisions compared to the volume of traffic through an intersection and is presented in crashes per million entering vehicles (c/mev). For signalized intersections, the statewide average is 0.80 c/mev and the district-wide (MassDOT District 5) average is 0.77 c/mev. A comparison of the calculated crash rate to this average rate can be used to establish the significance of collision occurrence. The calculated crash rate for Fall River Avenue Page 4 Road Safety Audit—Luther’s Corner: Fall River Avenue (Route 114A) at County Street Prepared by Greenman-Pedersen, Inc. (Route 114A) at County Street is 1.23 c/mev, which is well above both the statewide and district -wide averages. This rate was determined based on the 39 reported crashes at the signalized intersection, over the course of three years, utilizing counts from May 8, 2014. Crash data summaries, a collision diagram and a crash rate worksheet are included in the Appendix of this report. Speed Regulations Speed regulations maintained by MassDOT Highway Division establish a 30 mph speed limit for County Street in both directions in the vicinity of the intersection. This section of Fall River Avenue (Route 114A), however, has never been zoned and therefore holds no speed regulation. This arterial is posted at 35 mph approximately ½-mile north of the intersection.

Audit Observations Following an introduction to the RSA process and a summary of existing geometry, signal operations and crash and speed data, the audit participants were asked to discuss safety concerns at the subject intersection. Audit team members then drove to the intersection as a team, at which time observations were offered in the field. A summary of those in-field safety observations and potential deficiencies is provided below: Fall River Avenue (Route 114A) at County Street Pavement Conditions – At the time of the audit, low severity cracking on County Street and within the intersection was observed. Recent gas main utility maintenance was performed, requiring County Street pavement to be cut to access these mains. Both approaches of County Street were repaired with patching panels which since have settled causing an uneven travel way for vehicles. This may be contributable to poor compaction in the soil County Street: Eastbound approach pavement underneath the panel which conditions has settled. When this work was performed, the pavement markings on the eastbound approach, specifically the double yellow centerline line, were removed with the old pavement and never replaced. The age of the pavement suggests that the pavement friction has diminished over the years and therefore skid resistance has decreased. Collision data indiciates that four crashes (collision numbers 15, 18, 20, and 56) were attributable to wet pavement conditions. The crashes were an angle crash and rear-end crashes for the latter three, respectively. Research conducted by the Federal Highway Association, as well as the National Transportation Safety Boards, shows that about 70% of wet pavement crashes can be prevented or at least severity minimized by improved pavement friction. Pavement Markings – Pavement markings on Fall River Avenue (Route 114A) were observed to be visible, clear and reflective, with some wear at the time of the audit. The stop bar along the southbound approach of Fall River Avenue extends all the way across both the travel lane and the breakdown lane. These markings, in combination with the generous shoulder width, may give the Page 8 Road Safety Audit—Luther’s Corner: Fall River Avenue (Route 114A) at County Street Prepared by Greenman-Pedersen, Inc. impression to drivers that the breakdown lane on this approach is an available approach lane when in reality this approach is meant to be utilized as a single general purpose lane approach. Pavement markings on County Street were significantly worn at the time of the audit. The double yellow centerline on the eastbound approach of County Street is non existent in some areas due to pavement patch paneling. This can pose a safety issue as a double yellow centerline provides separation of traffic traveling in opposite directions and reduces head-on collisions although there were none were reported at this location. Crosswalks along all four approaches of the intersection were observed to have significant wearing at the time of the audit. Fall River Avenue (Route 114A) southbound approach: Stop bar extending across both the travel lane and breakdown lane. Faded crosswalks. Lane Geometry – The eastbound approach on County Street provides an exclusive right-turn lane and a shared through/left travel lane. Pavement markings are faded which may cause some confusion to unfamiliar drivers. However, there are R3-7 “Right Lane Must Turn Right” signs along the approach. Referring to the collision diagram and the crash data correlated to the diagram, collision number 41 occurred when an eastbound vehicle tried to pass on the right in the single lane before it splits into two. Although not seen in the crash data, there is a high possibility of a side-swipe type crash to occur on this approach when a vehicle attempting to access the exclusive right turn lane is hit by a thru movement vehicle passing a left turning vehicle in the right only lane. The Fall River Avenue (Route 114A) likelihood of this phenomenon is increased given single striped northbound lane that the eastbound left lane experiences a long utilized as two approach lanes queue, while there are little to no cars utilizing the exclusive right turn lane to make a right. Therefore, thru moving drivers are more inclined to try to pass left turning vehicles in this lane to be more efficient. The County Street westbound approach is one general purpose lane, not requiring any signage or markings. The Fall River Avenue (Route 114A) northbound approach is shown as two approach lanes on the existing signal layout however it is delineated as one general purpose lane. Despite the striping on this approach, it is currently being utilized as two lanes by vehicular traffic in practice. In the field it was noted that left-turning vehicles generally used the left side of the wide approach as a second lane. This may lead to confusion for unfamiliar drivers. Drivers entering the Page 9 Road Safety Audit—Luther’s Corner: Fall River Avenue (Route 114A) at County Street Prepared by Greenman-Pedersen, Inc. intersection from the south tend to stay to the right when going through or right and “hug” the centerline if turning left. However, if a left turning vehicle arrives at the stop bar first and positions itself in the middle of the lane, it heavily restricts northbound flow. Drivers in the “left lane” may realize that they are in the wrong lane and continue to travel north on Fall River Avenue. A crash may occur when a vehicle in the “through/right” lane is traveling northbound on Fall River Avenue at the same time and the two vehicles are forced to merge quickly into the receiving lane which is not wide enough to accommodate the two vehicles. This issue may be compounded as there are no lane merge signs. Currently there is approximately 20 feet available for vehicles traveling northbound, which is constricting when two vehicles are next to each other. Referring to the collision diagram and the crash data correlated to the diagram, crash number one (1) was a sideswipe crash in which a northbound vehicle was attempting to pass on the inside of the lane and did not have enough room. Fall River Avenue (Route 114A) southbound approach: Single general lane used as two lanes. Breakdown lane used as right turn lane. The southbound approach of Fall River Avenue is also one general purpose lane, not requiring any signage or markings. However it is currently being utilized as two lanes by vehicular traffic in practice. On this approach, right turning vehicles tend to use the breakdown lane as an exclusive right turn lane and the marked lane as a through/left lane. This is a concern for vehicles exiting the commercial driveways (Gulf and Dunkin Donuts) on Fall River Avenue. The crash history indicates that a number of collisions occur when vehicles exiting these driveways are waved on by one driver and the vehicle behind them tries to cut around them in the breakdown lane and an angle collision occurs as a result. Page 10 Road Safety Audit—Luther’s Corner: Fall River Avenue (Route 114A) at County Street Prepared by Greenman-Pedersen, Inc. Curb Radii- The existing curb radii on all corners of the intersection force tight right turns for vehicles, particularly the southbound and eastbound approaches. Larger vehicles must swing wide, encroaching on the left turning lanes on the northbound and eastbound approaches. Referring to the collision diagram and the crash data correlated to the diagram, crash number two (2) was a sideswipe-type crash in which a eastbound right turning truck encroached on the thru/left eastbound approach lane and hit a vehicle within that lane. It was noted in the field that box Tight Radii for larger vehicles making right trucks/tractor-trailers often hit or turn: Large vehicle encroaching left turn lane. scrape the utility poles that are in the northwest and southwest corners of the intersection. It was observed during the site visit that vehicles unable to make the right turn back-up in order to get enough room to safely execute the maneuver. Excessive Queuing – It was observed in the field that both approaches on Fall River Avenue (Route 114A) and the eastbound approach on County Street experience heavy queues throughout the day, especially during the evening commuter peak period. With this heavy queue comes aggressive and distracted driving potential, as drivers are waiting up to four cycle lengths to pass through the intersection. This issue could have contributed to the numerous rearHeavy queues along the County Street end type crashes which occurred eastbound approach. at the intersection. Rear-end crashes may occur when frustrated drivers attempt to clear the intersection even during yellow or red indication unaware that the driver in front intends to stop on the yellow or red indication. Many rear-end crashes are attributable to inattention as well, which is common when drivers wait multiple cycles to get through an intersection. Approximately 49 percent of all the crashes Page 11 Road Safety Audit—Luther’s Corner: Fall River Avenue (Route 114A) at County Street Prepared by Greenman-Pedersen, Inc. queried at this intersection were rear-end crashes. Referring to the collision diagram and the crash data correlated to the diagram, 14 of the 16 rear-end crashes to occur on the northbound, southbound and eastbound approaches were attributed to inattention. Signal Equipment – All vehicle signal heads are rigidly mounted on overhead mast arms. No backplates are present at this location and therefore, signal heads are potentially less visible. Emergency preemption is installed at this intersection; however the Seekonk Fire Department noted that the Department has issues with the system. The system was installed to allow improved emergency vehicle access on all approaches to the intersection by forcing a green indication on the approach of the emergency vehicle, allowing clear access. However, poor sight distance restricts the sensors on the emergency vehicles from being detected because of the slight curve along the southbound approach to the intersection. The opticom detectors are currently placed on the mast arm in the northwest corner and on the mast arm pole in the southwest corner. It should be noted that no emergency vehicles were involved in any crashes. Clearance Intervals – The purpose of the yellow and all-red clearance intervals is to provide a safe transition between two conflicting phases in traffic. A longer yellow interval may cause drivers to enter the intersection late, while a short interval may cause red violations and/or quick stops resulting in a rear-end collision. Of the crashes reviewed at this intersection, approximately 49 percent were rear-end type crashes. Grades - The down-hill grade of the westbound approach may increase the through vehicle’s speed and may be unexpected for an eastbound left turning vehicle. Referring to the collision diagram and the crash data correlated to the diagram, this may have been the case for crashes 46 and 49 which were both angle crashes involving a westbound through vehicle and an eastbound left tuning vehicle. Bicycle Accommodations – There are currently no bicycle accommodations along any of the approaches to the intersection, nor at the intersection itself. During the audit, RSA team members witnessed a bicyclist riding on the east sidewalk of Route 114A. Although no bicycle crashes were reported in the data, it was noted by the Seekonk Chief of Police as a safety issue. Page 12 Road Safety Audit—Luther’s Corner: Fall River Avenue (Route 114A) at County Street Prepared by Greenman-Pedersen, Inc. Pedestrian Accommodations – Currently there is an exclusive pedestrian phase that is serviced between the permitted mainline phase and side street phase. Crosswalks traverse all four approaches to the intersection. Pedestrian push buttons and signal heads are present on each corner for the associated crossing. Crosswalks were faded at the time of the audit. There are eight pedestrian signal heads, two on each corner of the intersection, that are antiquated 12” LEDs. An outlined walk symbol is activated by the push of the button and is present for seven seconds followed by a 12 second flashing don’t walk indication. The pedestrian signal head in the northeast corner of the intersection is covered by a tree and therefore pedestrians crossing in this direction Deteriorating sidewalks along County may be unaware of when it is safe to cross. Street. There is no audio alert provided during the exclusive pedestrian phase of the signal. The pedestrian signal heads do not provide a countdown notifying pedestrians of safe time remaining to cross. It was observed in the field that several vehicles were making a right on red which poses a conflict for pedestrians that are in the crosswalk. Sight distance is restricted for both pedestrians waiting to cross from the northwest corner and southbound drivers making the right onto County Street due to a utility pole and signal cabinet in the northwest corner. This is of particular concern as a majority of the pedestrian activity occurs on the eastbound approach of County Street. It was observed that many pedestrians were pressing the button and then walking when they did not have a walk indication. This in turn halted traffic unnecessarily for an exclusive pedestrian phase that was not being used, increasing delay for drivers. Sidewalks along Fall River Avenue (Route 114A) were in good condition at the time of the audit, ranging from five to seven feet wide with granite curbing. Sidewalks along County Street, on the other hand, were deterioirating and did not have granite curbing lining which provides a clear seperation from the roadway. It was noted the vehicles often park on the sidewalk along County Street. This is a pedestrian safety concern because the vehicle is now within the designated rightof-way for the pedestrian and it also takes away necessry space for a pedestrian to safely tranverse throughout the area. All of the pedestrian push buttons are ADA compliant push plungers except for the one serving the northeast corner. All wheelchair ramps are non-ADA compliant and do not have detectable warning strips. Signage – The RSA team noted several issues regarding signage in the vicinity of the intersection of Fall River Avenue (Route 144A) and County Street. Guide signage at the intersection is lacking. There is one blue street sign for County Street in the northwest corner of the intersection. Street signs for Fall River Avenue (Route 114A) are non-existent in advance or at the intersection. There is one sign in the south east corner of the intersection that directs drivers Page 13 Road Safety Audit—Luther’s Corner: Fall River Avenue (Route 114A) at County Street Prepared by Greenman-Pedersen, Inc. toward Interstate 195. No route signs for Route 114A are present in the vicinity of the intersection. No Parking signs line both sides of the southern leg of Fall River Avenue (Route 114A). There are multiple signs on both approaches of Fall River Avenue (Route 114A) that indicate “NO LEFT TURN 4:00 PM to 6:00 PM”. According to the counts and general observations from the audit team, many Lone guide sign for Interstate 195. drivers disregard this sign and execute the left turn maneuver during these hours. Several audit team members noted that there is no convenient alternative in the northbound direction to make a left downstream. This restriction is difficult to enforce during the heavy evening commuter peak period. It was mentioned that the Seekonk Police Department does not enforce this restriction, given the lack of a safe place to pull over a vehicle without seriously disrupting traffic. Referring to the collision diagram and the crash data correlated to the diagram, crashes 12 and 51 were angle crashes due to the driver failing to yield on the left turn during this specific time frame. Speeds – There are no speed limit signs within the vicinity of the intersection. Excessive speeding does not seem to be an issue due to the overall congestion and constricted feeling of the intersection. Access Management - Several businesses are located at or near the intersection of Fall River Avenue (Route 114A) and County Street. The Gulf gas station located in the northwest corner of the intersection has four wide and fairly nonformalized driveways, two on County Street and two on Route 114A. These wide curb cuts are often crossed by pedestrians, causing a longer period in which conflicts could occur. The close proximity of the Gulf gas station driveways to the intersection creates conflicts with the Route 114A southbound queues. Four angle crashes involved vehicles exiting the Gulf and southbound vehicles on Route 114A. These crashes may be considered “courtesy crashes”, where a Route 114A Wide curb cuts at the Gulf Gas Station in close proximity to the intersection. vehicle stopped to allow a vehicle to exit the gas station, but the exiting vehicle was subsequently struck by another southbound vehicle in the adjacent lane, in this case the Page 14 Road Safety Audit—Luther’s Corner: Fall River Avenue (Route 114A) at County Street Prepared by Greenman-Pedersen, Inc. breakdown lane. Two crashes involved Route 114A northbound vehicles waiting to turn left into the Gulf gas station and were rear-ended due to the close proximity to the intersection. RSA team members noted that many vehicles utilize these driveways to cut through and avoid the signal. Southbound drivers on Route 114A will cut through the gas station and head right onto County Street rather than waiting in the queue for the signal to turn green. This maneuver creates conflicts both within the Gulf station parking lot area as well as with drivers exiting the Gulf station onto County Street. There is also a Dunkin Donuts located just north of the Gulf Station on Fall River Avenue (Route 114A) which has a single formalized driveway that has experienced similar crash trends to those at the Gulf station. Two angle crashes involved vehicles on Route 114A southbound and vehicles turning right from the Dunkin Donuts driveway. These too may be considered “courtesy crashes”, where a Route 114A southbound vehicle stopped to allow a vehicle to exit Dunkin Donuts, but the exiting vehicle was subsequently struck by another southbound vehicle traveling in an adjacent lane. It was also observed in the field that there is some residential parking on the southbound approach of Fall River Avenue just north of the Dunkin Donuts as well as some bushes just south of Dunkin Donuts that may restrict sight distance and could be the cause of angle crashes. There was another angle crash involving a northbound vehicle turning left into the Dunkin Donuts and a southbound driver. This was a “courtesy crash” in which the initial southbound driver waved on the left turning northbound vehicle, but the entering vehicle was subsequently struck by Left turning vehicle out of Gulf Station and another southbound vehicle onto Rte. 114A North traveling in the breakdown lane. An additional two crashes occurred when a southbound driver stopped to let a northbound vehicle turn left into the Dunkin Donuts but was then rear-ended by another southbound vehicle. Traffic Signal Operations – RSA members observed that significant congestion occurs throughout the day especially during the evening commuter peak period. Currently the signal operates as a fully-actuated uncoordinated signal with three phases including an exclusive pedestrian phase. There are no protected left turns for any of the approaches and therefore significant delays occur on all approaches, especially both approaches on Fall River Avenue and the eastbound approach of County Street. Referring to the collision diagram and the crash data correlated to the diagram, there were six angle crashes within the intersection (collision numbers 12, 27, 43, 46, 49, and 51). Based on the collision trends and the operations of the signalized intersection, it is reasonable to Page 15 Road Safety Audit—Luther’s Corner: Fall River Avenue (Route 114A) at County Street Prepared by Greenman-Pedersen, Inc. assume that a majority of these incidents were the result of the permitted left-turn phasing on all approaches. Those familiar with the operations of the intersection stated that westbound vehicles frequently wave on the eastbound lefts because it is so difficult to make that turn. This could contribute to the rear-end collisions in the eastbound and westbound directions because it is contrary to the rules of the road. Therefore, drivers unfamiliar with Vehicle running red light. this behavior will not expect the driver in front to be waving on an opposing vehicle and in turn, rear-end them. It was noted by multiple RSA team members that the traffic signal does not seem to operate efficiently and vehicles often wait four cycles to get through the intersection. It is often observed that vehicles run the red light to get through the intersection rather than have to wait an additional cycle. Inefficiency at the signal may result in motorist inattention as well, which can lead to rear-end crashes. Nineteen rear-end crashes occurred on the approaches to the intersection, which may have been a result of motorist inattention combined with congestion. Potential Safety Enhancements After the intersection in-field visit, audit participants returned to the Seekonk Town Hall to discuss the safety issues and consider potential short-term and long-term improvements. Many of the potential enhancements identified during the RSA have already been considered as part of the design process, although further design work and consideration may be necessary to determine the feasibility of implementing the improvements moving forward. A summary of potential safety-related enhancements discussed at the RSA is provided below: Fall River Avenue (Route 114A) at County Street Pavement Conditions – The Project is intended to include various pavement rehabilitation treatments including standard overlay, structural overlay, and full depth reconstruction roadway sections. Improved pavement conditions will potentially reduce wet weather crashes. Pavement Markings – Markings will be refreshed as part of the project to be visible, clear and reflective. New retroreflective pavement markings will increase visibility during both daytime and nighttime conditions. In the short term, lane arrows can be installed on the northbound and eastbound approaches to indicate to drivers the appropriate lane they should use. This will reduce the possibility of a sideswipe crash since drivers will be more informed in advance of the Page 16 Road Safety Audit—Luther’s Corner: Fall River Avenue (Route 114A) at County Street Prepared by Greenman-Pedersen, Inc. intersection which lane is appropriate for their desired destination. Once the project is implemented, which is calling for two lane approaches with a dedicated left turn lane on the northbound, southbound, and eastbound approaches, lane use arrow markings will need to be updated and installed for these lane movements. Double yellow centerlines will be on all four approaches to separate opposing traffic and significantly reduce the potential for a head-on collision. Crosswalks will be refreshed as well, with the intent to draw more attention to the pedestrian. Sharrows will be incorporated along all four approaches to provide accommodations to bicyclists. Lane Geometry – As seen in the field, the Route 114A northbound approach is currently striped as one general purpose lane, however it is currently being used as two lanes in practice, with predominately left-turning vehicles utilizing the left edge of the lane as an exclusive lane, with through/right-turning vehicles utilizing a shared lane in the remaining right-of-way. In the short term, this approach can be striped as two approach lanes. Once the project it implemented, the proposed cross-section includes an 11 foot exclusive left turn lane, a 13 foot shared through/right lane, a 13 foot receiving/departure lane, and two foot shoulders with a minimum of 5.5’ sidewalks on both sides. This proposed cross-section will allow more room for vehicles to maneuver traveling northbound and therefore may reduce sideswipe crashes at this location. It is recommended that the southbound approach also be modified to provide two delineated approach lanes. The proposed cross section will be the same as the northbound approach with an 11 foot exclusive left turn lane, a 13 foot shared through/right lane, a 13 foot receiving/departure lane, and two foot shoulders with a minimum of 5.5’ sidewalks on both sides. By providing two lanes on this approach, the breakdown lane will be removed creating heightened awareness to drivers exiting the commercial driveways on Fall River Avenue (Route 114A) of vehicles traveling in both lanes. This may reduce some of the angle crashes occurring in these locations. The existing lane geometry on the eastbound approach of County Street provides an exclusive right turn lane and a shared through/left lane. It was noted in the field that excessive queues develop on this approach due to left turn vehicles waiting for a gap in traffic. Therefore, the eastbound approach will be converted to an exclusive 10 foot left turn lane, a 13 foot shared through/right lane, a 13 foot receiving/departure lane, and one foot shoulders with a minimum of 5.5’ sidewalks on both sides. Modifying these three approaches will alleviate some confusion that arises when lane geometry is unclear. The exclusive left turn lanes will reduce delay, reducing inattention and therefore the occurrence of rear-end collisions. In reviewing the traffic volume counts the Country Street westbound approach does not require an exclusive left turn lane, therefore this approach will remain as a single general purpose lane. The cross-section will be modified to include a 12 foot general purpose approach lane, a 12 foot receiving lane, and five foot shoulders with a minimum of 5.5’ sidewalks on both sides. Curb Radii – In order to provide ample room for large turning radii vehicles to execute a safe right turn, the stop bars can be placed further back on all approaches. Once the proposed left turn Page 17 Road Safety Audit—Luther’s Corner: Fall River Avenue (Route 114A) at County Street Prepared by Greenman-Pedersen, Inc. lanes are installed as part of the project, this will reduce the potential for these right turning vehicles to encroach the left turn lane. The intersection would benefit by relocating the utility poles currently in each of the four corners of the intersection. These utility poles are located in close proximity to the roadway. Relocating the utility poles would eliminate the possibility of them being hit or scraped by large vehicles executing a right turn. Consideration will be made to placing the signal equipment at the back of the sidewalk, if possible. Excessive Queuing –With the installation of the exclusive left turn lanes, implement protective/permissive phasing for the northbound and eastbound approaches. The southbound and westbound approach will remain as permissive only left turns. Enhanced signal operations will reduce the amount of cut through traffic in adjacent neighborhoods, as locals voiced has been a concern in the area for quite some time. The reduction in vehicle volume on these residential streets will improve the state of living as it will reduce noise and increase safety for children. Signal Equipment – Retroreflective backplates shall be added to all signal heads in order to make them more visible and conspicuous during both daytime and nighttime conditions. This may reduce unintentional red-light running. In the event that the “flashing yellow arrow” traffic control be implemented as part of the protective/permissive phasing for the northbound and eastbound approaches, additional signal heads will be required along these approaches to adhere to MUTCD standards. Install additional opticom receivers to be mounted on extensions to improve sight line for emergency vehicles. This will allow for the receivers to detect an emergency vehicle well in advance of the intersection and allow enough time for the intersection to clear before the emergency vehicle arrives. This will potentially improve emergency response time over existing conditions. Clearance Intervals – Evaluate the yellow and red clearance times to determine if they are set to the current standards and adjust as necessary. A potential adjustment may reduce the occurrence of red light running, as well as rear-end type crashes. Grading – As the design allows, adjust the grading along County Street to allow for improved sight distance. Bicycle Accommodations – The shared through/right lanes proposed on the northbound, southbound, and eastbound approaches will also operate as a shared bike lane. Sharrows will be implemented within the corridor in order to alert to vehicle users that bicyclists are likely to be within the traveled way as well. The sharrows will also assist bicyclists with a safe lateral positioning in lanes that are too narrow to accommodate both a motor vehicle and a bicycle to travel side by side in the same traffic lane. The westbound approach of County Street is to have 5 foot shoulders which will serve as a bike lane for bicyclists on this approach. Sharrows. Page 18 Road Safety Audit—Luther’s Corner: Fall River Avenue (Route 114A) at County Street Prepared by Greenman-Pedersen, Inc. Pedestrian Accommodations – In order to further enhance pedestrian accommodations at the intersection, install 16” LED countdown pedestrian signal heads with audible and vibro-tactile pedestrian pushbuttons in conjunction with the R10-3e sign and saddle with a LED confirmation light. Install ADA compliant wheelchair accessible ramps with detectable warning strips. All sidewalks throughout the project area are to be replaced with a continuous, minimum 5.5 foot wide Portland cement concrete sidewalk lined with granite curbing to clearly delineate the roadway from the walkway. Relocate the utility pole and possibly the signal cabinet in the northwest corner to allow for improved sight distance for both pedestrians and right-turning southbound vehicles. As right on red turns are permitted during the exclusive pedestrian phase, evaluate the need for the installation of R10-15 sign “Turning Vehicles Yield to Pedestrians” in order to further protect pedestrians. Coordinate with the Seekonk Public Schools to implement a program that educates children on properly crossing the crosswalk using the pedestrian push buttons. Also coordinate with the Labonte Auto School located just south of the intersection on Fall River Avenue (Route 114A) about educating students about not only how to properly cross as a pedestrian but also how to be aware of how to share the roadway and increase safety for all users as a driver. Signage – Install street signs for Fall River Avenue (Route 114A) and County Street on the overhead mast arms. Similar directional signage could also be useful for directing vehicles to the interchange with Interstate 195, south of the intersection. Directional signs for I-195 should also be installed in advance of the intersection so that motorists may position themselves in the correct lane prior to reaching the intersection, reducing the occurrence of angle crashes. Install “Advance Intersection Lane Control” variation (R3-8b) signage on both approaches of Fall River Avenue (Route 114A) and the eastbound County Street approach to the intersection, advising drivers of the oncoming lane uses. Install “Turning Vehicles Yield to Peds” (R10-15) on the southbound and eastbound approach as the County Street eastbound crosswalk is very active. Also install “Pedestrian Signs” (R10-3 e) on all four corners adjacent to the proposed vibro-tactile pedestrian push buttons to further enhance pedestrian safety. Remove all “No Left Turn 4PM-6PM” signs and allow for this movement to be unrestricted. Speeds – Consider undertaking a speed study and zoning this portion of Route 114A as it currently does not hold a speed regulation. Access Management – In order to reduce “courtesy crashes” consider restricting left turns from commercial driveways on Route 114A. To reduce courtesy crashes, work with the owners of the Gulf Gas Station and Dunkin Donuts to arrange a shared parking arrangement that would reduce Page 19 Road Safety Audit—Luther’s Corner: Fall River Avenue (Route 114A) at County Street Prepared by Greenman-Pedersen, Inc. conflict points along Fall River Avenue (Route 114A). Work with the owner of the Gulf Gas Station to better formalize driveways, narrow the curb cuts, and ideally, close the two driveways closest to the intersection. To reduce cut-through traffic through the Gulf gas station, coordinate with the owner to implement strategies such as making one driveway entrance-only, installing speed humps along the cut-through route, or narrowing the curb cut. Prohibit parking on Fall River Avenue north of the Dunkin Donuts to improve sight line for vehicles exiting the Dunkin Donuts. Traffic Signal Operations – Change the phasing of the intersection to include protective/ permissive phasing for the eastbound and northbound approaches to be implemented by use of the “flashing yellow arrow” traffic control. The “flashing yellow arrow” traffic control will minimize delay as there will be more opportunities to make a left turn. NCHRP Report 493: The Evaluation of Traffic Signal Displays for Protected/Permissive Left-Turn Control2, a national study conducted by the National Cooperative High Research Program, indicated that the “flashing yellow arrow” display significantly reduces driver confusion when executing a left turn. It was stated within the report that some drivers believe that they are also protected under the green ball indication, leading to angle crashes. The protected/permissive phasing to be installed for the northbound and eastbound approaches will eliminate this confusion. The protected/permissive phasing should reduce the need for courtesy waves by providing clear protected intervals for left turns as well as clear permitted intervals to turn when adequate gaps appear in opposing traffic. This should reduce the frequency of westbound vehicles waving on eastbound lefts and therefore reduce those related rear-end collisions in the eastbound and westbound directions from drivers unfamiliar with this behavior. Summary of Road Safety Audit Based on observations and discussions, the RSA team identified the issues and possible enhancements that could improve safety at the intersection of Fall River Avenue (Route 114A) and County Street in Seekonk, Massachusetts. Many of the enhancements identified will be studied to determine feasibility as part of the design process for the MassDOT intersection improvement project at Luther’s Corner. Table 2 summarizes the existing safety issues, possible enhancements, estimated safety payoff, time frame, cost, and responsible agency for Fall River Avenue (Route 114A) at County Street. Safety payoff estimates are subjective and 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 (>3 years). The costs are categorized as low (<$10,000), medium ($10,001 to $50,000), or high (>$50,001). 2 National Cooperative Highway Research Program Report 493: Evaluation of Traffic Signal Displays for Protected/permissive Left-Turn Control, Transportation Research Board of the National Academies, 2003.
