3 Road Safety Audit Route 135 at Route 30 -, MA Background The Federal Highway Administration (FHWA) defines a Road Safety Audit (RSA) as the formal safety examination of an existing or future road or intersection by an independent, multidisciplinary team. The purpose of an RSA is to identify potential safety issues and possible opportunities for safety improvements considering all roadway users. This RSA evaluates the intersection of South Street/Milk Street (Route 135) at East Main Street/West Main Street (Route 30)/Brigham Street, as shown in Figure 1. A safety audit was scheduled for this high crash intersection at the request of ficials. The intersection of South Street/Milk Street (Route 135) at East Main Street/West Main Street (Route 30)/Brigham Street, which is configured as a rotary intersection, was identified as a Highway Safety Improvement Program (HSIP) intersection for A key objective of the RSA is to identify both short-term and long-term safety improvements that can be made at the subject intersection and incorporated in potential improvements of this intersection. Project Data A Road Safety Audit was completed for the intersection of South Street/Milk Street (Route 135) at East Main Street/West Main Street (Route 30)/Brigham Street in the on November 19, The agenda for the RSA meeting held at the Forbes Municipal Building is provided in Appendix A of this report. As shown below in Table 1, the audit team consisted of a multidisciplinary team with representatives from state, regional and local agencies providing expertise in the engineering, planning, maintenance and emergency response fields. Contact information for the RSA attendees is provided in Appendix B of this report. Page 1

Sidewalks are provided on both sides of the roadway; no bicycle amenities are provided. Angle parking is provided on a portion of the Milk Street receiving lanes. Parallel on-street parking is provided on the left side of the Milk Street approach to the rotary. Milk Street provides a single lane into the rotary as well as an exclusive right turn lane to West Main Street. East Main Street (Route 30) is a two-way, two-lane roadway that extends in a north-south direction through the, extending to Route 9 to the north. East Main Street (Route 30) is classified as an urban minor arterial under jurisdiction. At the study area intersection, East Main Street provides a through lane into the rotary as well as an exclusive right turn lane to Milk Street. Sidewalks are provided on both sides of East Main Street and angle parking is provided on the western side of the roadway. Bicycle amenities are not provided. West Main Street (Route 30) is a two-way, two-lane roadway that extends in a north-south direction through the. West Main Street (Route 30) is classified as an urban minor arterial under jurisdiction. At the study area intersection, East Main Street provides a single lane into the rotary. Sidewalks and angle parking are provided on both sides of West Main Street. Bicycle amenities are not provided. Brigham Street is a two-way, two-lane roadway that extends in an east-west direction connecting to Bay State Commons. Brigham Street is classified as a local roadway under jurisdiction. At the study area intersection, East Main Street provides a single lane into the rotary. Sidewalk and angle parking are provided on both sides of West Main Street. Bicycle amenities are not provided. Study Area Intersections The unsignalized intersection of South Street/Milk Street (Route 135) at East Main Street/West Main Street (Route 30)/Brigham Street is a five-legged rotary in the center of the. The Brigham Street and Milk Street approaches are under stop control while the remaining three approaches on East Main Street, West Main Street, and South Street are under yield control. South Street approaches from the southeast and provides two lanes entering the rotary. Brigham Street enters from the east, East Main Street enters from the north, Milk Street enters from the west, and West Main Street enters from the south, each providing a single lane of access to the rotary. The rotary has two circulating lanes between South Street and the Milk Street receiving lane, while the remainder of the rotary provides a single circulating lane. There is no signing or striping provided for this lane utilization within the rotary. There are sidewalks and crosswalks available around the rotary as well as two pedestrian crosswalks within the rotary (one adjacent to West Main Street and one adjacent to Brigham Street), as seen in Figure 1. Crash Data Crash data was received from the Police Department for the years Based on this data, there were a total of 69 crashes reported from the beginning of 2012 through the end Page 3

6 Road Safety Audit Route 135 at Route 30 -, MA of 2014 at the intersection of South Street/Milk Street (Route 135) at East Main Street/West Main Street (Route 30)/Brigham Street. Of the 69 crashes that occurred in the time period reviewed, 22 crashes are angle collisions between rotary traffic and vehicles entering from East Main Street (Route 30) from the north. Overall, 54% of the crashes that occurred at this location were angle collisions. A total of seven crashes were sideswipe collisions with parked vehicles adjacent to the intersection. A total of eight crashes were the result of rear-end collisions at various locations within the rotary, one of which occurred as a pedestrian crossed at the marked crossing spanning the rotary adjacent to Brigham Street. The pedestrian was not struck. The most commonly reported driver contributing factors in the reported crashes were either failure to yield the right of way or inattention. A detailed crash diagram is provided in Appendix C. Page 4

9 Road Safety Audit Route 135 at Route 30 -, MA Road Safety Audit Observations and Potential Improvements During the RSA meeting prior to the field visit, a brief introduction of the RSA process and a summary of traffic volumes and crash information were presented to the audit participants. Following this brief presentation, the members of the audit team were asked to discuss the existing issues that may affect safety at the intersection of South Street/Milk Street (Route 135) at East Main Street/West Main Street (Route 30)/Brigham Street. The audit team then visited the site as a group, at which time observations of various safety concerns and deficiencies were identified and documented. Provided below is a list of the safety concerns that were identified during the RSA for each intersection and for the corridor as a whole and the potential enhancements identified during the RSA. Safety Issue #1: Parking Observations: There are angle parking spaces present in several locations within and adjacent to the rotary. During the RSA meeting, audit participants noted that the angle spaces in these areas are in conflict with traffic circulating through the rotary and adjacent roadways. The most notable areas of concern were the parking space within the rotary (adjacent to the Arcade building) and the parking spaces along South Street. The Arcade building is adjacent to six parking spaces on the Angle parking adjacent to the Arcade Building within the rotary western side of the rotary, as shown in Figure 2, and restricts the rotary at this point to a single circulating lane. The parking along South Street is also angled parking and is along a horizontal curve, creating a sight distance problem for vehicles exiting the rotary to see vehicles exiting parking spaces. Sight distance was also noted at the Milk Street approach to the rotary and is obstructed by the spaces in front of the Arcade building. Angle parking along South Street In a review of the crash data, seven crashes reported were the result of a vehicle colliding with a parked car adjacent to the rotary. Additionally, two crashes were specifically due to vehicles backing out of angle spaces on South Page 7

10 Road Safety Audit Route 135 at Route 30 -, MA Street. Audit team members discussed potential issues with property owners within the rotary and the elimination of parking. It was also noted that the parking adjacent to the rotary helps slow traffic this intersection. Additionally, it was discussed that there is a municipal parking lot on South Street adjacent to the rotary that team members believe is underutilized. Enhancements: Consider eliminating parking within the rotary to allow for a reduction in conflict points for vehicles circulating though the rotary. Consider converting existing parking on South Street and West Main Street to parallel parking to eliminate angle parking conflicts between backing vehicles and vehicles in the travel lane. The conversion to parallel parking may allow for right of way to add additional streetscape elements such as wider sidewalks or bike lanes. Consider converting the parking on South Street to reverse angle parking where vehicles reverse into the parking spaces and then are able to pull out head first when exiting parking spaces. It should be noted that the median on South Street should be extended with the implementation of this improvement to restrict vehicles from pulling into a parking space on the opposite side of the roadway. Have a formal parking utilization study prepared to determine the parking utilization for on-street parking spaces and the municipal parking lot to determine potential reallocation of parking in the downtown area. Safety Issue #2: Pedestrian/Bicycle Operations Observations: Audit team members discussed the existing pedestrian and bicycle facilities and operations around the rotary. There are crosswalk connections at each rotary approach as well as in two locations within the rotary. It was noted that recently, curb extensions were installed at the crosswalk spanning the rotary to the east of West Main Street as well as at the South Street crosswalk to help protect pedestrians crossing adjacent to the angled on-street parking. Crosswalk within the rotary at West Main Street Audit team members noted major conflicts with pedestrians at the crosswalk within the rotary adjacent to Brigham Street. At this location, traffic from South Street and traffic from Brigham Street are entering the rotary, and there are two lanes of traffic circulating through the rotary. Less frequent conflicts were also noted at the second crosswalk within the rotary, between West Main Street and South Street. Page 8

11 Road Safety Audit Route 135 at Route 30 -, MA The crosswalk spanning the Milk Street receiving lane was also discussed. Currently, traffic from East Main Street has an exclusive right turn lane with a large turning radius into this crossing. The crossing is also very long, extending through angle parking on the northern side of the roadway. At several crosswalks around the rotary, it was also noted that there pedestrian warning signage was missing. Additionally, it was noted that all of the crossings occur at the stop line entering the rotary where vehicles are mainly focused on vehicular traffic and available gaps in traffic to enter the rotary. Providing crossings at these locations may be an additional conflict. Bicycle operations were also discussed by audit team members as members from the Town Bicycle and Pedestrian Advisory Committee were present. It was noted that the rotary has little direction for cyclists and that there is not a clear message to motorists that they must share the road with cyclists through the rotary. Vehicle speeds were also discussed as a hazard to cyclists. Cyclist operations through the rotary It was also noted that the two lanes on Milk Street entering the rotary are separated by a striped island measuring approximately five feet in width. While the function of this island may be to delineate the right turning traffic and discourage right turning traffic to enter the rotary, it is not functioning effectively. The inclusion of this striped island creates a longer crossing for pedestrians, and the additional space could be used to more effectively promote and alternative mode of travel, such as a bicycle lane. Enhancements: Consider eliminating existing crosswalks within the rotary, requiring pedestrians to circulate around the rotary rather than through it to reduce pedestrian conflicts with vehicles. Alternatively, consider eliminating only the crosswalk within the rotary at Brigham Street to reduce conflicts between pedestrians and vehicles while still maintaining the crossing spanning the rotary adjacent to West Main Street to provide access to the center island. Consider adding additional curb extensions to shorten the crossings around the rotary. This will also act as a traffic calming measure to slow traffic within the rotary, further improving pedestrian safety. Consider providing appropriate pedestrian crossing signage at all pedestrian crossings around the rotary to provide a clear message to motorists that there are pedestrian crossings within the rotary. Page 9

12 Road Safety Audit Route 135 at Route 30 -, MA Consider providing supplemental Rectangular Rapid Flashing Beacons (RRFBs) at the crossings to alert motorists of a crossing pedestrian. Evaluate providing a pedestrian curb extension on the northern side of the Milk Street receiving lane to shorten the crossing for pedestrians and reduce the turning radius for the southbound right turn. Evaluate relocating the crosswalks on each approach leg back from the stop line to allow motorists to focus solely on the crosswalk before entering the rotary. Consider providing right turns yield to pedestrians signage to help protect pedestrians in the crosswalk within the rotary from West Main Street. Consider widening sidewalks adjacent to the rotary to further encourage pedestrian usage. Consider providing a sidewalk on the northern side of the Arcade Plaza (Milk Street) to provide a continuous walking path adjacent to the rotary. Evaluate providing sharrows within the rotary and on adjacent approaches and departure lanes to indicate to motorists and cyclists that the road is shared by both users. Sharrows may be most helpful on West Main Street adjacent to Town Hall, South Street adjacent to Cottage Street, Milk Street exiting the rotary, and East Main Street adjacent to Union Street. Consider eliminating the striped island on Milk Street entering the rotary and evaluate the addition of a bicycle lane to further protect cyclists entering the rotary. Safety Issue #3: Lane Designation Observations: Audit team members noted that there is currently a lack of lane designation through the rotary. The rotary is supposed to allow two circulating lanes from South Street to the Milk Street receiving lanes. The rightmost lane entering from South Street is not intended to continue though the rotary past Milk Street, but there is no signage or striping to indicate this. Audit team members noted that there have been conflicts involving drivers who are Existing lane utilization markings on South Street unaware that the second circulating lane ends at Milk Street as they continue through the southern portion of the rotary. The missing lane designation signage and striping may be a contributing factor in the number of angle collisions that occurred in the rotary as vehicles entering the rotary are unsure where to go and to which street circulating vehicles are intending to travel. Page 10

13 Road Safety Audit Route 135 at Route 30 -, MA It was also noted that the South Street approach is often used as three lanes entering the rotary as the rightmost lane provides enough width for right turning vehicles destined to Brigham Street to bypass the two through lanes. Enhancements: Considers adding lane striping within the rotary to provide guidance for where vehicles should travel. Consider adding lane utilization pavement markings at each approach in advance of the rotary to provide guidance on lane utilization. Consider providing lane utilization signage at each approach in advance of the rotary to provide supplemental guidance on lane utilization. Consider decreasing the lane width of Typical lane utilization markings that provide direction through a modern roundabout the rightmost lane at South Street to prohibit right turning vehicles from bypassing the through movement queue entering the rotary. Safety Issue #4: Signage Observations: It was noted by audit participants that there is insufficient rotary signage approaching the rotary as well as within the rotary. Due to the unique geometry of this rotary, it should be clearly marked that vehicles must circulate to the right. There is also outdated signage for the rotary, specifically on the southbound approach from East Main Street, that does not comply with current standards. It was also noted that there are a significant number of signs that may be unnecessary or not optimally placed around the rotary. Existing signage within the rotary It was also noted that while there is on-street parking widely available in the downtown area surrounding the rotary, there is no direction to the off-street municipal lot located on South Street. Page 11

14 Road Safety Audit Route 135 at Route 30 -, MA Enhancements: Reduce sign clutter to provide a clear, concise message to motorists. Consider updating any outdated signs with signs conforming to current standards to help provide a clear message to motorists. Consider providing larger rotary signage to indicate to all approaches that they are entering a rotary. Consider providing advanced W2-6 (Circular Intersection) warning signage in advance of the rotary to provide additional guidance to motorists as they approach the intersection. Consider providing supplemental chevron signage (R6-4) to guide motorists through the rotary. Evaluate wayfinding signage to the off-street parking lot to reduce the amount of onstreet parking conflicts downtown. Safety Issue #5: Vehicle Speeds Observations: Vehicle speeds were noted by audit team members to be a major issue contributing to the large volume of crashes that were recorded between the East Main Street approach and rotary traffic. Vehicles entering the rotary are often continuing through to West Main Street and do not yield to rotary traffic. Additionally, there is an issue with the high speeds at which vehicles travel East Main Street approach entering the rotary from the South Street approach to Milk Street, which was noted by audit participants as a contributing factor to the high number of crashes at this location. In a review of the crash data, 24 of the 69 crashes were angle collisions between the East Main Street approach and rotary traffic, and an additional three crashes were due to the operations of the southbound right turn. Enhancements: Consider providing advanced warning signage for the upcoming rotary to warn motorists to yield at the rotary. Page 12

15 Road Safety Audit Route 135 at Route 30 -, MA Consider providing rumble strips on East Main Street to alert motorists that they should be reducing speeds approaching the rotary. Evaluate relocating the existing yield sign on East Main Street back to increase visibility. Consider modifying the right turn radius from East Main Street to Milk Street to reduce the vehicle speeds of right turning vehicles. Safety Issue #6: Roadway Geometry Observations: The existing rotary has a unique geometry which differs from a modern roundabout. The center island is off-center and approaches to the rotary do not have the typical deflection that is required in a modern roundabout, which is particularly an issue for the southbound approach from East Main Street where there are no visual cues for motorists due to the lack of deflection. It was also discussed that vehicles use the southbound right turn lane from East Main Street to continue through into the rotary to avoid the queue in the correct lane. This causes additional conflicts and potential for sideswipe collisions as vehicle enter the rotary at this location. Enhancements: Evaluate retrofitting the existing rotary to comply with existing geometric standards for a roundabout, including the installation of truck aprons at target locations (such as the East Main Street median) to help formalize the rotary travel lane and reduce vehicle speeds. Consider providing a channelizing island for the right turn from East Main Street to Milk Street to restrict vehicles from continuing into the roundabout. Safety Issue #7: Traffic Control Observations: Audit participants noted that the traffic control entering the rotary is unique to a typical rotary. The Milk Street and Brigham Street approaches are stop controlled while the remaining approaches are yield controlled. This creates confusion on which approach has the right of way, particularly at the West Main Street/Milk Street approach. West Main Street is under yield control; however, both the Milk Street and West Main Street approaches operate as stop controlled approaches as they must alternate right of way to allow the Milk Street approach into the rotary at peak times. The West Main Street traffic also cannot see that Milk Street is stop controlled as the stop sign is obscured by a Do Not Enter sign. Union Street to the north of the rotary connects East Main Street to Bay State Commons. The intersection provides a right turn only from Union Street to East Main Street. However, vehicles are making left turns from this approach to access the rotary instead of using the signalized Bay State Commons driveway to the north or Brigham Street to the south. Page 13

16 Road Safety Audit Route 135 at Route 30 -, MA Enhancements: Update the signage at the Milk Street approach to allow the stop sign to be seen from the West Main Street approach to convey a clear message of appropriate traffic operations to motorists. Evaluate changing West Main Street to a stop controlled approach to allow improved operations on Milk Street and reduce confusion between the two approaches. Evaluate extending the median on East Main Street to continue past the Union Street intersection to provide a physical barrier to restrict left turns from Union Street. Safety Issue #8: Commuter Rail Bridge Operations Observations: Audit participants discussed the impacts on the rotary of the commuter rail bridge to the north on East Main Street. The bridge provides a 12-6 clearance that is commonly struck by vehicles that do not meet those height requirements. If the bridge is struck, traffic at the roundabout is impacted as vehicles are not able to travel this critical leg. Recently, mitigation was installed in the form of a laser detector system. The laser detectors are installed in advance of the crossing and illuminate signage for vehicles that do not meet height requirements. While it is difficult to determine the effectiveness of this countermeasure, the audit participants generally agree that it has been a benefit, but that additional countermeasures may help deter larger vehicles from using East Main Street. Enhancements: Consider providing a physical warning obstacle such as chains or bars in advance of the bridge to warn motorists exceeding the height limits of the bridge. Consider providing additional warning signage in advance of the bridge to warn drivers of the low bridge. Safety Issue #9: Traffic Operations Observations: Audit participants discussed issues with traffic congestion due to the operations of the traffic signal at the intersection of East Main Street and the Bay State Commons driveway during the weekday morning peak hour. Traffic queues from the intersection in the northbound direction extend back to the rotary, creating traffic congestions problems within the rotary. Enhancements: Evaluate traffic operations at the intersection of East Main Street and the Bay State Commons driveway to provide for improved traffic flow on East Main Street and reduce the likelihood of northbound vehicle queues impacting the rotary. Page 14

17 Road Safety Audit Route 135 at Route 30 -, MA Recommendations After the site visit, audit participants returned to discuss the safety issues and consider various improvements. The audit participants were encouraged to consider both short and long-term improvements for each of the existing safety issues. Each improvement considered has been categorized as short-term, mid-term, or long-term based on the definitions shown in Table 2. Additionally, a cost category has been assigned to each improvement based on the parameters set forth in Table 2. Table 2.
