Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL Background The Road Safety Audit (RSA) is one of the first steps in the design process as well as a necessary step for the project to be eligible to receive Highway Safety Improvement Program (HSIP) federal funds for construction. The goal of this RSA is to identify potential safety issues that can be addressed with shortterm improvements prior to construction and long-term improvements that can be incorporated into the design. All improvements should adhere to the Massachusetts Department of Transportation (MassDOT) guidelines for intersection design. The RSA is a collaborative process by state, municipal, law enforcement, public works, and design consultants. The process involves conducting a meeting to discuss current crash data and safety issues at the site, visiting the site to discuss possible solutions that would improve safety, and preparing a written report that outlines the safety issues discussed along with the costs, timeline, and agency responsibility for implementing improvements. Project Data Nitsch Engineering has been retained by MassDOT to complete an RSA for the intersection of Main Street (Route 28) at North Main Street and Old Main Street ( the study intersection ) in Yarmouth, MA. Prior to the RSA, Nitsch Engineering reviewed background materials provided by MassDOT, Cape Cod Commission, and the Town of Yarmouth. The study intersection was ranked #50 in MassDOT s 2014 Top Crash Locations Report 1. MassDOT provided the last four years of available crash data (2012-2015), including a summary table and charts, and corresponding collision diagram. We used the data to establish a crash rate at the study intersection to compare to the MassDOT Average Crash Rates per Million Entering Vehicles (MEV) 2. For signalized intersections, the Statewide average is 0.77 per MEV, and the District 5 average, which includes the Town of Yarmouth, is 0.76 per MEV. At the study intersection, for the four-year period 2012-2015, a total of 33 crashes were documented, yielding a crash rate of 0.80 per MEV, which is above both the Statewide and District 5 averages. The crash data and the Crash Rate Worksheet are included in Appendix C. Cape Cod Commission provided the most recent available traffic counts, including both Automatic Traffic Recorder (ATR) counts and Turning Movement Counts (TMCs). The ATR counts were taken along Main Street (Route 28), east of North Main Street/Old Main Street, from Monday, August 8, 2016 at 12:00 PM to Thursday, August 10, 2016 at 2:00 PM. Cape Cod Commission provided TMC data from two different dates: Wednesday, August 11, 2010 from 7:00 AM to 9:00 AM to capture the weekday morning traffic peak hours, and Wednesday, August 24, 2016 from 4:00 PM to 5:30 PM to capture the weekday evening traffic peak hours. The traffic counts are included in Appendix D. 1 2014 Top Crash Locations Report, Massachusetts Department of Transportation (MassDOT), August 2016 2 The 2016 Average Crash Rates, per Million Entering Vehicles, by Intersection Type, MassDOT, Highway Division Page 1

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL The Town of Yarmouth provided additional background information, including a concept plan for the study intersection with proposed improvements from 1995, and a map of the South Yarmouth/Bass River National Register Historic District, which includes the study intersection. Both documents are included in Appendix D. On Friday, December 2, 2016, Nitsch Engineering conducted the RSA for the intersection of Main Street (Route 28) at North Main Street and Old Main Street in Yarmouth, MA The RSA occurred during dry and sunny conditions. As indicated in Table 1, the audit team consisted of representatives from MassDOT, the Town of Yarmouth, and Cape Cod Commission. The group observed operations with respect to safety at the study intersection and this report documents the audit team s findings. The RSA agenda can be found in Appendix A.

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL Project Location and Description The Locus Map of the study area is shown in Figure 1. An aerial map of the study intersection of Main Street (Route 28) at North Main Street and Old Main Street is shown in Figure 2. Main Street (Route 28) at North Main Street and Old Main Street Main Street (Route 28) in Yarmouth is classified as an urban principal arterial that runs in the east-west directions through the project area. Massachusetts Route 28 overall, however, is designated as a north-south route, with its southern terminus in Eastham and its northern terminus in Methuen at the New Hampshire state line, where it continues as New Hampshire Route 28. The roadway is maintained by MassDOT and serves approximately 17,000 vehicles per day east of the project intersection. The speed limit along Main Street (Route 28) through the intersection is 30 miles per hour (mph). North Main Street in Yarmouth runs in the north-south directions through the project area. North Main Street is classified as an urban principal arterial through the intersection, and as an urban minor arterial north of Station Avenue, approximately 250 north of the intersection. The roadway is present from its southern terminus at the project intersection for approximately two miles to its northern terminus, just north of U.S. Route 6 where it continues as North Dennis Road. The speed limit along North Main Street is 30 mph through the intersection and 25 mph north of Station Avenue. The roadway is maintained by the Town of Yarmouth. Old Main Street in Yarmouth is classified as an urban minor arterial that runs in a general northeastsouthwest direction. Old Main Street is approximately one mile long with both termini intersecting Main Street (Route 28). The roadway is maintained by the Town of Yarmouth. The speed limit along Old Main Street is 30 mph through the intersection. The study intersection is controlled by a fully-actuated, uncoordinated traffic signal, however audit participants noted that the existing traffic loops used for vehicle detection may not be functional and the traffic signal controller may be defaulting to maximum recall for each phase. During summer months, the intersection experiences an increase in traffic when compared to the remainder of the year, as Yarmouth is a popular location for vacationers due to the presence of several beaches and tourist destinations. As such, the increase in traffic volumes during summer months exacerbates many of the issues outlined in this report. The study intersection is primarily located within the South Yarmouth/Bass River National Register Historic District. Thus, available right-of-way for potential safety improvements may be limited due to the proximity of the buildings located on the northeast and southwest corners to the abutting roadways and the intersection. North Main Street at Station Avenue Though the intersection of North Main Street and Station Avenue was not originally included in the scope of this RSA, due to its proximity to the study intersection and the angle at which Station Avenue intersects North Main Street, audit participants noted that the traffic operations at this intersection may affect those at the study intersection, and should therefore be included as part of the RSA. Page 3

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL Station Avenue in Yarmouth is classified as an urban principal arterial that runs in the northwest-southeast direction. The roadway intersects North Main Street on its west side approximately 250 feet north of the study intersection, and provides access to U.S. Route 6 approximately two miles northwest of the intersection with North Main Street. The speed limit along Station Avenue is 30 mph near the intersection. The roadway is maintained by the Town of Yarmouth. The intersection of North Main Street and Station Avenue is unsignalized, with North Main Street operating freely, and Station Avenue operating under YIELD control. Audit participants noted that the Station Avenue approach previously operated under STOP control, and the control was modified to YIELD conditions roughly ten years ago. Page 4

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL Audit Observations and Potential Safety Enhancements Main Street (Route 28) at North Main Street and Old Main Street Traffic Operations Observation: The existing traffic signal system is outdated with respect to current MUTCD3 standards with respect to mast arm location and type, traffic signal indications, lack of signal backplates, vehicle detection, and lack of emergency preemption. Enhancement: Install a new traffic signal system that conforms to current MUTCD standards and respects the historical context of the intersection and the nearby historic resources, including but not limited to: steel mast arms, new signal indications with retroreflective backplates, new vehicle detection, and emergency vehicle preemption. Observation: Audit participants noted the existing traffic loops used for vehicle detection may not be functional, and the traffic signal controller may be defaulting to maximum recall for each phase. Enhancement: Investigate the functionality of the existing traffic signal loops used for vehicle detection, and repair if not functioning properly. Observation: The intersection clearance ( yellow plus all-red time) for each of the four approaches may not be adequate given the observed 85 th percentile travel speed, and may be a contributing factor to angle crashes 4, 7, 11, 14, 16, 21, 22, 32 and rear-end crashes 8, 9, 20, 24, 25, 28. Additionally, vehicles passing through the intersection after the signal has turned red (red-light running) may also be a contributing factor to angle crashes 4, 16, 21, and 32. Enhancement: Evaluate the clearance intervals and re-time the signals appropriately. Observation: The Main Street (Route 28) eastbound and westbound approaches each have exclusive left-turn lanes but no protected left-turn phase. The lack of exclusive left-turn phase may have contributed to angle crashes 7, 11, 14 and 22. Crashes 12 and 17 at the Main Street (Route 28) eastbound approach, which are rear-end crashes involving vehicles backing up, may also have been due to the lack of a left-turn phase. Audit participants noted that vehicles enter the intersection while waiting to turn left against oncoming traffic, and those that are unable to execute the turn before the northbound/southbound phase begins, back up into traffic so they do not impede the path of southbound vehicles through the intersection. Enhancement: Investigate if exclusive left-turn phases are warranted at Main Street (Route 28) eastbound and westbound to reduce the number of collisions that result from left-turning vehicles. If warranted, modify the phasing to include a protected 3 Manual on Uniform Traffic Control Devices (MUTCD), 2009 Edition Page 7

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL and/or protected-permissive phase, and install new signals with Flashing Yellow Arrow (FYA) indications. Observation: The exclusive left-turn lanes at the Main Street (Route 28) eastbound and westbound approaches, and the North Main Street southbound approach each provide only approximately 100 feet of vehicle storage. Audit participants noted the storage is insufficient and vehicles frequently block the adjacent shared through/right-turn lanes at each approach. Enhancement: Determine the feasibility of extending the existing left-turn lanes to increase vehicle storage. Observation: The tight North Main Street southbound right-turn movement may be difficult to navigate given the radius of the northwest corner, which may be the cause of crash 26. Audit participants noted that heavy vehicles may be using Long Pond Drive as an alternate route to avoid this movement. Enhancement: Re-evaluate the radius between North Main Street southbound and Main Street (Route 28) westbound, and if appropriate, reconstruct the northwest corner to further accommodate turning movements. Representatives from the Town of Yarmouth indicated that the property on the northwest corner of the intersection is owned by the Town, which may streamline the design process. Signage Observation: There is no R3-7 Left Lane Must Turn Left signage in advance of the intersection nor at the stop line for the Main Street (Route 28) eastbound and North Main Street southbound approaches. Enhancement: Install R3-7 Left Lane Must Turn Left signage in advance of and at the intersection along the Main Street (Route 28) eastbound and North Main Street southbound approaches to limit vehicle lane changes close to the intersection. Observation: The guide signs for the Old Main Street northbound approach, which are located on the northeast corner, are angled improperly such that they are visible to the Main Street (Route 28) westbound approach and may lead to confusion. Enhancement: Rotate the existing guide signs on the northeast corner such that they are only visible from the Old Main Street northbound approach. Page 8

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL Looking west, the guide signs on the northeast corner for northbound traffic are visible to westbound traffic Observation: Main Street (Route 28) westbound is the only approach that does not contain an R10-11b4 No Turn on Red (NTOR) designation, which may be warranted based on lack of available sight distance looking left. Furthermore, the NTOR designation does not appear to be observed from the other approaches, and may be the cause of crash 18. Enhancement: Investigate if a NTOR designation is warranted for Main Street (Route 28) westbound and, if warranted, install an R10-11b4 No Turn on Red sign. If appropriate, relocate the existing No Turn on Red signage for the other approaches in accordance with the MUTCD for improved visibility. Visibility Observation: The signal indications are of incandescent-type, and may lack the appropriate quantity of illumination for proper observation. Furthermore, there are no backplates which may make it difficult to identify the signal indication when the sun is low on the horizon, particularly the Main Street (Route 28) approaches. Enhancement: Install new signal indications with retroreflective backplates, which may require new signal heads and mast arms. 4 Ibid Page 9

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL Aluminum mast arms, with incandescent signals and no backplates Observation: The 5-section doghouse signal indicating the protected-permissive phase for North Main Street southbound left-turns is located on the mast on the southeast corner of the intersection, as opposed to the typical location on the overhead mast arm, which may be difficult to observe for vehicles advancing within the queue. Enhancement: Replace the 5-section doghouse signal with a 4-section signal including FYA indication. The new signal would require installation of a new mast arm, and should be located overhead to increase visibility for vehicles advancing within the queue. Looking south, the doghouse signal located on the southeast corner of the intersection may be difficult to observe Page 10

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL Observation: The rightmost signal for the Old Main Street northbound approach is blocked by vegetation, which may have contributed to crash 25. The rightmost signal for the North Main Street southbound approach is blocked by the adjacent building and vegetation, which could have contributed to crash 28. Enhancement: Trim vegetation at the Old Main Street northbound and North Main Street southbound approaches to improve visibility of signals and signage. Looking north, the rightmost signal cannot be observed due to vegetation Looking south, the rightmost signal cannot be observed due to the adjacent building and vegetation Access Management Observation: Angled parking is present on the east side of North Main Street just north of the intersection, and vehicles turning from Main Street (Route 28) onto North Main Street may not have adequate stopping sight distance to stop for vehicles backing onto North Main Street from an angled parking space. The presence of the parking lane in proximity to the intersection may have contributed to crash 5. Additionally, no shoulder line is present adjacent to the angled parking, which may give the impression of two travel lanes in the absence of any parked vehicles. Audit participants commented that the angled spaces are relatively short, such that the rear of a parked vehicle either extends into the traveled way or drivers pull the vehicle forward onto the sidewalk to fit the vehicle within the parking space. Audit participants also noted that there is an additional parking in the rear of the existing building, however, businesses rely heavily on the presence of the angled parking spaces in the front of the stores. Enhancement: In conjunction with the business owners along North Main Street, investigate the parking options for patrons and consider removing some of the angled parking spaces along North Main Street and/or converting to a parallel parking lane to increase sight distance from the intersection. Based on what is determined, consider adding a shoulder line. Page 11

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL Beginning of angled parking lane Looking north, the angled parking lane on North Main Street may be too close to the intersection for adequate stopping sight distance Observation: The existing gas station curb cut on the east side of Old Main Street just south of the intersection may not have adequate sight lines due to the presence of vegetation, which is most likely the cause of angle crash 1. Drivers along Old Main Street may have to stop or slow down to allow vehicles to exit the driveway, which may have contributed to rear-end crash 15. Enhancement: Investigate if the permitted movements of the existing gas station driveway on Old Main Street can be modified to be right-in/right-out only to reduce the number of collisions that result from vehicles turning left into and out of the driveway. If permitted, install R3-25 No Left Turn and R6-15 One-Way signage and furnish new pavement markings. Observation: The curb cut for the municipal parking lot on the south side of Main Street (Route 28), just east of Mill Lane and adjacent to the Olympia Fish House, is approximately 130 feet long. This excessive opening allows patrons to turn into and out of the parking lot onto Main Street (Route 28) at any location along the curb cut frontage, which creates many vehicle conflict points and may lead to vehicles jockeying for positioning during high volume times. This could potentially be the cause of angle crashes 6 and 10, where vehicles exiting the property collided with eastbound vehicles along Main Street (Route 28). 5 Ibid Page 12

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL Enhancement: Reduce the width of the curb cut for the municipal parking lot adjacent to the Olympia Fish House and consider locating the curb cut on Main Street (Route 28) as far from the intersection as possible to reduce vehicle conflicts proximate to the intersection. Looking east, the municipal parking lot curb cut on Main Street (Route 28) may be too long, creating many vehicle conflict points, and may lead to vehicles jockeying during high volume times (Source: Google) Pedestrian Accommodations While there are no documented pedestrian crashes, we found the following safety issues and recommend the subsequent enhancements to improve conditions for pedestrians, especially those with limited mobility: Observation: The pedestrian signals are outdated, with scripted Walk and Don t Walk indications, no countdown display, faded and obsolete signage, and small push buttons, which may require applying excessive pressure. Furthermore, many of the existing pedestrian displays were not functional, and the pedestrian display on the southwest corner was turned to an angle that made it difficult to observe while waiting to cross from both the northwest and southeast corners. Enhancement: Investigate if the non-functioning pedestrian signal displays can be repaired, and if so, repair for the short-term until they can be replaced with new signals. Enhancement: Rotate the signal head on the southwest corner to face the crosswalks such that they can be seen from the northwest and southeast corners. Enhancement: Install a new pedestrian signal system compliant with current standards, including but not limited to signal displays with countdown, tactile push buttons, and Accessible Pedestrian Signals (APS). Page 13

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL Pedestrian signal indications are scripted and not functional; push buttons are non-standard Pedestrian signal head on the southwest corner is angled and difficult to see from the crosswalk terminus Observation: Audit participants noted that the pedestrian Walk, flashing Don t Walk, and steady Don t Walk times may be inadequate. Enhancement: Evaluate the pedestrian walk and clearance time, and re-time the signals in compliance with the MUTCD if necessary. Page 14

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL Observation: There are several issues with the existing pedestrian ramps and adjacent sidewalks: Each corner of the intersection contains one apex pedestrian ramp, rather than two perpendicular ramps, which is undesirable due to the relatively long crossing distance and can be confusing for the visually-impaired. Visually-impaired pedestrians rely on the position and angle of the detectable warning panel to access the adjacent crosswalk, and in the case of an apex ramp, pedestrians could be improperly guided directly into the middle of the intersection. The existing pedestrian ramps and sidewalks, particularly on the southeast corner, contain various obstructions that impede the movement of pedestrians and are therefore not compliant with Americans with Disabilities Act (ADA) and Massachusetts Architectural Access Board (MAAB) guidelines. Without having an existing layout plan available during the RSA, audit participants speculated this could be problematic for future intersection improvements based on the current sidewalk limits, and may require additional Right of Way (R.O.W.) takings. The signal mast on the southeast corner does not provide adequate horizontal clearance for pedestrians; the apex ramp at the corner is undesirable There is no curbing along the north side of Main Street (Route 28), which provides no grade separation to protect pedestrians from vehicles. There are two additional pedestrian ramps located on the southeast corner of the intersection offset from the apex ramp, one on the south side of Main Street (Route 28) just east of the intersection, and one on the east side Looking west, there is no curbing on the north side of Main Street (Route 28), which leaves little protection for pedestrians (Source: Google) Page 15

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL of Old Main Street just south of the intersection. The presence of these additional ramps may cause confusion to pedestrians as they are not located at a crosswalk and could improperly lead pedestrians into the traveled way. The two additional pedestrian ramps on the southeast corner, one on the east side of Old Main Street (left) and one on the south side of Route 28 (right), are not located at a crosswalk and could cause confusion Enhancement: Re-evaluate the necessity of the apex pedestrian ramps, remove or relocate the additional pedestrian ramps on the southeast corner, and reconfigure the ramp layout and adjacent sidewalks as necessary in compliance with current ADA and MAAB standards, including but not limited to, removal of obstructions, adequate horizontal clearance, and grade separation. Observation: Audit participants noted an approximately 3 high breakaway sign post obstruction on the north side of Main Street (Route 28) just west of the intersection, which could be a tripping hazard. Enhancement: Remove the sign post tripping hazard. The sign post on the northwest corner of the intersection poses a tripping hazard; The signal mast does not provide adequate horizontal clearance for pedestrians Page 16

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL Observation: There is existing signage on the northwest and southwest corners of the intersection directing travelers towards the beach. These signs are not compliant with the MUTCD, and are mounted low and do not provide adequate vertical clearance for pedestrians. Enhancement: Replace the existing directional beach signage with signage compliant with the MUTCD, and install with appropriate vertical clearance. Bicycle Accommodations The existing signage pointing towards the beach poses a vertical clearance issue While there are no documented bicycle crashes, we found the following safety issue and recommend the subsequent enhancement to improve conditions for bicycles: Observation: There are no bicycle accommodations present along Main Street (Route 28), North Main Street, or Old Main Street. The Town of Yarmouth has indicated it has plans to increase the desirability of bicycling within the study area. Bus Accommodations Enhancement: Install bicycle accommodations by providing exclusive or separated bicycle lanes where possible. Observation: There are existing Cape Cod Regional Transit Authority (CCRTA) bus stops located on Main Street (Route 28) eastbound and westbound just west of the intersection, however, there are no turnouts present in either direction, with little room for a bus to pull out of the traveled way. This can reduce the traffic flow and could contribute to collisions of vehicles attempting to circumvent the bus. Enhancement: Determine the feasibility of providing bus turnouts near the CCRTA bus stops. Page 17

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL Lighting Observation: Audit participants noted that lighting is only present on the northwest and southeast corners of the intersection, which may not be adequate at night, particularly for pedestrians. Enhancement: Install additional lighting at the intersection. Drainage Observation: Audit participants noted the proximity of the intersection to Bass River and its Nitrogen-impaired Bass River Watershed, and potential issues with drainage can increase the likelihood of vehicle crashes. Enhancement: Any intersection improvements should adequately incorporate drainage, stormwater management, and stormwater treatment into the design to reduce the likelihood of crashes, taking into consideration the impaired Bass River Watershed. North Main Street at Station Avenue Traffic Operations Observation: The YIELD control on Station Avenue eastbound may be unexpected, as STOP control may be more typical for an intersection of this type, which may be the cause of crashes 2 and 30. Audit participants noted that the Station Avenue approach was previously under STOP control, and control was modified to YIELD roughly ten years ago. Furthermore, the angle at which Station Avenue meets North Main Street coupled with the YIELD control may also be confusing for Station Avenue eastbound left-turning vehicles, and is likely the cause of crash 29. Audit participants speculated that Station Avenue contained the larger volume of vehicles at this intersection, and questioned if Station Avenue eastbound should operate as the free movement and North Main Street southbound should operate under STOP control. Cape Cod Commission confirmed this speculation in a post-rsa correspondence, indicating that per past traffic volume studies, Station Avenue serves approximately 6,000 vehicles per day, while North Main Street serves approximately 3,000 vehicles per day. Enhancement: Re-evaluate the existing YIELD control at the Station Avenue eastbound approach, and determine if the traffic control at the intersection should be modified. Enhancement: Evaluate the geometry at the intersection, and based on the control determination, consider realigning Station Avenue to intersect North Main Street at as close to a 90-degree angle as possible, or installing a roundabout or a mini-roundabout, if feasible. Page 18

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL Signage Observation: There is no advanced warning signage along Station Avenue approaching the intersection with North Main Street, and due to the both the geometry and YIELD control, the intersection may be unexpected. Enhancement: Provide adequate advanced warning of the intersection, regardless of the control determination. Observation: Traveling north on North Main Street to Station Avenue, the wayfinding signage to U.S. Route 6 is not compliant with the MUTCD and may be difficult to observe due to its size and placement. Enhancement: Replace the existing wayfinding signage to U.S. Route 6 at the intersection of North Main Street and Station Avenue with standard guide signs in conformance with the MUTCD. The wayfinding signage at the corner of North Main Street and Station Avenue is not standard and may be difficult to observe Visibility Observation: The existing YIELD sign on Station Avenue is rotated slightly away from the roadway and may be blocked by vegetation during summer months. Enhancement: Rotate the existing YIELD sign towards the roadway at the Station Avenue approach. Enhancement: Clear any vegetation that potentially blocks the YIELD sign at the Station Avenue approach. Page 19

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL The YIELD sign for Station Avenue is rotated away from the roadway and may be blocked by vegetation during summer months Access Management Observation: Pemberton Road is a local road that runs parallel to and located approximately 175 north of Main Street (Route 28) and 75 feet south of North Main Street at Station Avenue. Audit participants noted that Pemberton Road provides access to off-street parking and is frequently used as a cut-through to avoid backups at the study intersection. Due to the relatively narrow width of Pemberton Road, the roadway resembles a driveway or alley, and the number of vehicles turning in and out of the roadway may be unexpected. This may be problematic due to its proximity to both intersections, particularly for vehicles yielding and likely looking left from the Station Avenue approach who may not have adequate time to stop for vehicles turning in or out of Pemberton Road. This access management issue may have been a contributing factor in crash 33. Enhancement: Install W2-26 (Horizontal Alignment/Intersection Sign Side Road) signage with supplemental W16-8P6 Pemberton Road plaque to provide warning of Pemberton Road for vehicles traveling along North Main Street southbound and Station Avenue eastbound. 6 Ibid Page 20

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL Looking north, Pemberton Road is proximate to both the project intersection and Station Avenue, and vehicles yielding from Station Avenue may not have adequate stopping sight distance (Source: Google) Pedestrian Accommodations Observation: There is little pedestrian connectivity at the intersection of North Main Street and Station Avenue, particularly across North Main Street, which may have been the cause of crash 31. Bicycle Accommodations Enhancement: Based on the control determination at the intersection of North Main Street and Station Avenue, investigate providing pedestrian connectivity, including the installation of additional sidewalk, pedestrian ramps, and/or the installation of crosswalks at the intersection. Observation: There are no bicycle accommodations present along Station Avenue. The Town of Yarmouth has indicated it has plans to increase the desirability of bicycling within the study area. Enhancement: Install bicycle accommodations by providing exclusive or separated bicycle lanes where possible. Page 21

Road Safety Audit Main Street (Route 28) at North Main Street and Old Main Street, Yarmouth Prepared by Nitsch Engineering 9720.15 Task #2 FINAL Summary of Road Safety Audit Nitsch Engineering has been retained by MassDOT to complete an RSA for the intersection of Main Street (Route 28) at North Main Street and Old Main Street in Yarmouth, MA. We incorporated the intersection of North Main Street and Station Avenue to the scope of this RSA due to its proximity and its effect of the traffic operations at the study intersection. We tabulated the safety issues and potential safety enhancements discussed during the RSA, with the associated potential safety payoff, the estimated time frame for completion, the estimated construction cost, and the responsible agency. Table 2 shows the breakdown of the estimated time frame and cost. Safety payoff estimates are subjective and are based on engineering judgment and the perceived likelihood that the proposed safety enhancement will reduce the quantity and severity of future crashes.
