4 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Background This Road Safety Audit (RSA) was conducted as part of MassDOT s roadway reconstruction project for Route 38 (Main Street) in Wilmington. The purpose of the RSA was to identify and discuss existing safety issues and potential improvements considering different roadway users. Both long term improvements that can be implemented as part of the Main Street project and short term improvements were discussed. There were 144 reported crashes along the corridor from 2013 to of those crashes were within the four MassDOT Highway Safety Improvement Program (HSIP) crash clusters within the project area. HSIP crash clusters are locations that are in the top 5% for the region in terms of the number of crashes. Approximately 71% of the crashes were property damage only. Approximately 74% of crashes were rearend or angle-type collisions. The safety audit team was composed of representatives from MassDOT Highway Safety, MassDOT District 4, Wilmington Police Department, Wilmington Fire Department, Town of Wilmington Planning Department, Wilmington DPW, Boston Region Metropolitan Planning Organization (MPO), and Green International Affiliates, Inc. (Green). Project Data The RSA for Main Street in Wilmington was conducted on Thursday, January 26, The RSA agenda is provided in Appendix A. Table 1 lists all members of the audit team, and the RSA Audit Team Sign-in sheet is included in Appendix B. The RSA began with Green International Affiliates, Inc. (Green) giving a brief presentation of the existing conditions and crash data history to facilitate the start of the discussion. The audit team then drove to the four intersections of Main Street identified as MassDOT HSIP crash clusters and identified observed safety issues. The group also discussed potential issues that occurred along the corridor. The four observed intersections that were observed were Main Street at Route 62, Main Street at Route 129, Main Street at Cross Street/Butters Row, and Main Street at Eames Street. Next, the audit team reconvened to summarize the safety concerns identified in the field and discussed potential improvements to address these safety concerns. Page 1

The project limits along Main Street extend from 400 feet north of the intersection with Route 62 to the Woburn Town Line for an approximate length of 2.2 miles. The RSA focused on the following intersections as well as the segments along Main Street between these intersections: Route 38 at Route 62 (signalized) Route 38 at Route 129 (signalized) Route 38 at Cross Street/Butters Row (unsignalized) Route 38 at Eames Street (unsignalized) Background research was performed for the above intersections, and the roadway segments between these intersections and to the project limits. Wilmington Police Department and State Police Department crash data were collected and organized into a collision map and collision diagrams. Appendix C provides the count data, collision map, crash summary table, collision diagrams, and MassDOT crash rate worksheets for each intersection and for the segment of the project roadway limits.

6 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Existing Roadway and Intersection Descriptions Route 38 (Main Street) Route 38 (Main Street) provides access to I-495 in Tewksbury to the north and I-95 in Woburn to the south. Main Street is a two lane, two-way road that is classified as an Urban Principal Arterial roadway, and is under MassDOT jurisdiction. The roadway carries traffic in the north-south direction. The posted speed limit varies from miles per hour depending on location and direction. Main Street is approximately 30 to 35 feet wide from Route 62 to Route 129 with two foot lanes and 1-3-foot shoulders. South of the intersection with Route 129, Main Street is 32 feet wide with two 14-foot lanes and 2-foot shoulders. At the intersections with Route 62 and Route 129, which are signalized, each approach of Main Street has two lanes except for the Northbound approach at Route 129 which has only one lane. At the intersections with Cross Street/Butters Row and Eames Street, which are unsignalized, each approach of Main Street has only one lane. The project location is shown in Figure 1. Land use adjacent to Main Street north of Route 129 is commercial use. There are frequent curb cuts for driveways and side streets along this section of Main Street. South of the intersection with Route 129 the land use is commercial, residential, and recreational, with significantly fewer curb cuts and side streets. Each intersecting street is owned and maintained by the Town of Wilmington. Route 129 is classified as a Principal Arterial, Route 62 and Eames Street are classified as Minor Arterials and Butters Row and Cross Street are classified as Major Collectors under state jurisdiction. Sidewalks are present on all sides of the intersections of Route 38 and Route 62 and Route 38 and Route 129. But there are no sidewalks present at any other point in the corridor. There are no bicycle lanes or markings along the project corridor and shoulders are never more than three feet wide. Route 38 (Main Street) at Route 62 (Church Street/Burlington Avenue) - Signalized At this intersection, Church Street serves as the east leg and Burlington Avenue serves as the west leg. Main Street forms the north and south legs. Route 62 provides access to I-93 in the east and Route 3 in the west. Burlington Avenue forms the west leg as a bridge which goes over the commuter rail railroad that runs parallel to Route 38. The commuter rail railroad is part of the Haverhill Line and the Wilmington stop is just a few hundred feet north of this intersection. There is a significant increase in pedestrian and vehicular traffic at this intersection during the morning and afternoon peak hours for the commuter rail. There are two lanes for each approach with each inside lane being approximately 11 feet wide and each outside lane being approximately 12 feet wide. There are sidewalks present along both sides of Main Street and Route 62 and there are crosswalks across the north, south, and east legs. Pedestrian signal heads and pushbuttons are provided at each crosswalk. The signals operate with a leading protected leftturn phase for Main Street northbound traffic, a phase for Main Street northbound and southbound during which left turns are permitted, a lagging protected left turn phase for Main Street southbound traffic, and split phasing for Route 62 eastbound and westbound traffic. A pushbutton-actuated exclusive pedestrian phase is provided. Page 3

7 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Route 38 (Main Street) at Route 129 (Lowell Street) Signalized At this four-legged intersection, Route 129 (Lowell Street) serves as the east leg, a private driveway forms the west leg, and Route 38 (Main Street) forms the north and south legs. Route 129 provides access to I-93 in the east. The intersection is surrounded by commercial businesses, which creates additional potentials for crashes within the queue lanes when cars are turning in and out of the businesses. There are two lanes for the Main Street southbound approach that are each 10 feet wide. The inside lane is a left turn only lane. There are two lanes for the westbound Lowell Street approach, including a 12-footwide shared through/left-turn lane and a 14-foot-wide exclusive right turn lane. The northbound Main Street approach has only one lane, which is 13 feet wide. There are sidewalks present along both sides of all three legs of the intersection and there are crosswalks across the north leg and the east leg. Pedestrian signal heads and pushbuttons are provided at each crosswalk. The signals operate with a leading Main Street southbound protected left turn phase, a northbound/southbound through phase with a southbound flashing yellow arrow, and an eastbound/westbound phase. A westbound right turn overlap is provided during the southbound protected left-turn phase. Turns on red are prohibited from the Route 129 westbound approach. A pushbutton-actuated exclusive pedestrian phase is provided. Route 38 (Main Street) at Cross Street/Butters Row Unsignalized At this skewed, two-way STOP-controlled intersection, Cross Street serves as the east leg and Butters Row serves as the west leg. Route 38 (Main Street) forms the north and south legs. Cross Street provides access from Route 38 to Route 129 and Butters Row primarily serves residential traffic. Opening this spring is a public park (Yentile Farm) located east of the intersection. The addition of this park is expected to increase pedestrian, cyclist, and vehicular traffic. The Butters Row eastbound and Cross Street westbound approaches are placed under STOP control. All approaches have only one lane. The Route 38 (Main Street) approaches are approximately 14 feet wide while the Butters Row and Cross Street approaches are approximately 10 feet and 8 feet wide, respectively. There are no sidewalks or crosswalks at the intersection. There is a 13-foot-wide, two-way bridge over the railroad tracks along Butters Row, approximately 300 feet west of the intersection with Main Street (Route 38). Main Street at Eames Street Unsignalized At this four legged, one-way STOP-controlled intersection, Eames Street forms the east leg, a private driveway forms the west leg, and Route 38 (Main Street) provides the north and south legs. Eames Street primarily provides access to industrial parks and connects to Woburn Street in Wilmington. The Eames Street westbound approach is placed under STOP control. Each approach has only one lane. The Route 38 (Main Street) southbound approach is approximately 12 feet wide, the Route 38 (Main Street) northbound approach is 14 feet wide and the Eames Street westbound approach is 10 feet wide. There are no sidewalks or crosswalks at the intersection. Page 4

9 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Audit Observations and Potential Safety Enhancements: Route 38 (Main Street) Corridor In conducting the Route 38 Road Safety Audit, existing safety issues and possible corrective actions were identified based on audit team discussions and field observations on Thursday, January 26, The safety issues that were identified along the project corridor of Route 38 (Main Street) include: Faded or improper pavement markings Non-compliant/substandard pedestrian accommodations Lack of bicycle facilities Lack of access management Poor/insufficient signage and wayfinding Ineffective drainage Poor pavement conditions Many of these issues can or need to be addressed by long term solutions, but some short-term improvements were also identified. The following paragraphs describe the issues at and possible actions for this intersection. The identified issues by the RSA team have some similarities and commonalities and consequently, were grouped into major categories. Safety Issue #1. Faded or Improper Pavement Markings Observations There is a section of the centerline on Route 38 (Main Street) between Cross Street/Butters Row and Eames Street that is very faded. The center passing lane on Main Street between Route 129 (Lowell Street) and Cross Street/Butters Row is also faded. This stretch of Route 38 (Main Street) has a posted speed limit of 40 and 45 miles per hour. There are many points along the corridor where the shoulder line has faded as well. Faded or missing shoulder or center lines could cause drivers to drift off the road or out of their lane and into oncoming traffic. Ultimately ending in head-on collision or single vehicle crashes with objects off the road. Enhancements 1. Consider restriping the shoulder and center lines along Route 38 (Main Street). This will help drivers avoid drifting out of their lanes. Safety Issue #2. Non-Compliant/Substandard Pedestrian Accommodations Observations There are no sidewalks or crosswalks south of the intersection of Route 38 (Main Street) with Route 129 (Lowell Street). This creates a greater potential for pedestrian collisions. Page 6

10 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Enhancements 1. To improve pedestrian safety, evaluate the feasibility of installing sidewalks along both sides of Main Street between Route 62 (Burlington Avenue / Church Street) and Route 129 (Lowell Street), due to the high amount of commercial businesses. 2. Additionally, consider the feasibility of adding sidewalks on one side of Route 38 (Main Street) between Route 129 (Lowell Street) and Cross Street/Butters Row as well as between Cross Street/Butters Row and Eames Street. Safety Issue #3. Lack of Bicycle Facilities Observations There are no bicycle accommodations along any part of the corridor and all the shoulders are less than four feet wide. With few bike lanes and narrow shoulders there is more of potential for vehicle collisions with cyclists. Additionally, the new public park (Yentile Farm) near the intersection of Main Street with Cross Street and Butters Row will potentially create more bicycle traffic. There was one collision with a cyclist between 2013 and 2015 along the corridor. It occurred along the section of Main Street between Route 62 (Burlington Avenue / Church Street) and Route 129 (Lowell Street) in the northbound direction. Enhancements 1. To improve cyclist safety, consider the feasibility of providing a continuous bicycle lane, or a shoulder wide enough to accommodate cyclists, along both sides of the Route 38 (Main Street) corridor. Roadway widening would be needed in some sections north of Route 129 (Lowell Street) which would require Right of Way takings. Safety Issue #4. Lack of Access Management Observations Due to the high density of business driveways along Route 38 (Main Street) between the Route 62 (Burlington Avenue / Church Street) and Route 129 (Lowell Street) intersections, vehicles are frequently taking left turns through gaps in Route 38 (Main Street) traffic. However, due to the high traffic volume along each direction of Route 38 (Main Street), drivers are forced to wait a long time to find a safe gap and may choose inadequate gaps posing safety risks. Furthermore, due to the lack of left-turn lanes along Route 38 (Main Street), there is a significant risk of rear-end collisions when drivers traveling straight are not suspecting the presence of stopped vehicles in their lane. Page 7

11 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Of the total 144 crashes that occurred along the corridor between 2013 and 2015, 43 were on this portion of Main Street between the Route 62 (Burlington Avenue / Church Street) and Route 129 (Lowell Street) intersections. Enhancements 1. Consider adding a left-turn lane or two-way left-turn lane at different locations to give drivers waiting to turn left from Route 38 (Main Street) a safe place to wait for a gap in oncoming traffic. 2. Consider working with adjacent business owners to consolidate driveways and reduce the number of conflict points. Reducing the number of conflict points will make it easier for drivers to know where vehicles are entering traffic and therefore reduce the chance of crashes. 3. Coordinate with business owners and evaluate the feasibility of restricting left turns into and out of driveways. This will also reduce the number of conflict points for vehicles on Main Street Safety Issue #5. Poor/Insufficient Signage and Wayfinding Observations It was noted that many of the signs along the corridor are outdated. For example, the Lane Ends (W4-2) sign south of the Route 38 (Main Street) at Route 62 (Church Street/Burlington Avenue) intersection is not compliant with MUTCD standards. Outdated signs could lead to driver confusion which increases the risk of the driver taking a quick, unexpected turn that cause any type of collision. Enhancements 1. Replace outdated signs that are not compliant with the current MUTCD standards to avoid driver confusion. Page 8

12 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Safety Issue #6. Ineffective drainage Observations Ponding was noted in the shoulders along the Route 38 (Main Street) corridor in front of the U-Haul building location and in front of Triple Nickel Auto Body Repair. Enhancements 1. To avoid wet roadway related crashes such as hydroplaning, evaluate the feasibility of redesigning the drainage systems on Route 38 (Main Street) at the U-Haul and in front of Triple Nickel Auto Body Repair. Image 1: Ponding in front of Triple Nickel Auto Body Repair Safety Issue #7. Poor Pavement Conditions Observations Along the shoulder of Route 38 (Main Street) southbound in between Route 62 (Burlington Avenue / Church Street) and Route 129 (Lowell Street), there are large holes in the shoulder. These holes pose a hazard to vehicles traveling in the shoulder who are passing vehicles waiting to take left turns into the many businesses along this segment. Enhancements 1. Repave shoulders where there are potholes so that vehicles will not be damaged when pulling over to the side of the road. Image 2: Ponding in potholes along shoulder of Main Street Page 9

13 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Audit Observations and Potential Safety Enhancements: Route 38 (Main Street) at Route 62 (Burlington Avenue/Church Street) In conducting the Route 38 Road Safety Audit on Thursday, January 26, The safety issues that were identified at the intersection of Route 38 (Main Street) at Route 62 (Burlington Avenue/Church Street) include: Faded or improper pavement markings Intersection geometry deficiencies Non-compliant/substandard pedestrian accommodations Substandard signal equipment and phasing Poor/insufficient signage and wayfinding Poor sight distances Many of these issues can or need to be addressed by long term solutions, but some short-term improvements were also identified. The following paragraphs describe the issues at and possible actions for this intersection. The identified issues by the RSA team have some similarities and commonalities and consequently, were grouped into major categories. Safety Issue #1. Faded or Improper Pavement Markings Observations The introduction to the left-turn pocket on the northbound approach at the intersection of Route 38 with Route 62 is abrupt. Currently, there is no white dotted extension line to delineate the opening of the left turn pocket, instead there is a faded broken white line that starts 80 feet after the opening of the left turn pocket. Additionally, northbound vehicles preparing to enter the left turn lane to turn on to Burlington Avenue drive over the double yellow line to avoiding waiting in the long queue in the right-through lane. Enhancements 1. Restripe the taper of the left-turn lane along Route 38 northbound with a dotted line to signify an opening turn lane to give notice and visibility that the left turn lane begins. This would give people more warning that the turn pocket is present and would help avoid rear-end and side-swipe crashes. Page 10

14 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Safety Issue #2. Intersection Geometry Deficiencies Observations The southbound approach provides turn lanes that travel through the intersection, and merges to one lane just south of the intersection. Due to the heavy volume of vehicles travelling southbound during both peak periods of the day, and the short merging distance, southbound drivers often merge within the intersection. There were two sideswipe crashes reported between the years 2013 to 2015 just south of this intersection which could have been caused by the short southbound merging area. It was noted that it is difficult for tractor trailers to turn left from southbound Route 38 to Church Street or to turn right from westbound Church Street to northbound Main Street. This can be seen from crashes 13, 18, and 20. Enhancements 1. To avoid sideswipe crashes, evaluate the feasibility of widening the southbound departure to provide a longer merging area for the southbound vehicles. 2. Evaluate the feasibility of lessening the skew of Church Street to the intersection to make the tractor trailer turning movement easier to and from the north leg of the intersection. Safety Issue #3. Non-Compliant/Substandard Pedestrian Accommodations Observations There were no pedestrian related crashes at this intersection. All wheelchair ramps are missing detectable warning panels and there are non-ada compliant slopes on the sidewalk on the northwest and southwest corners of this intersection. There are inconsistent crosswalk patterns at this intersection. Two only have two 12 white lines on each side of the walk area and one is the standard ladder style crosswalk. The two crosswalks with only the two 12 lines are on the north and south legs of the intersection. The standard style crosswalk is on the east leg. The pedestrian Flashing Don t Walk (FDW) clearance time is too short for all three crosswalks, that are all about 70 feet long. The walk time is sufficient but the Image 3: The two crosswalks at the Main Street and Route 62 intersection are different. Page 11

15 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates FDW is only 5 seconds long where it should be about 20 seconds, based on MUTCD, in case someone began walking just as the FDW began. Additionally, this intersection experiences an influx of pedestrians shortly after a commuter rail train stops at the nearby station. The short pedestrian phase means that pedestrians may still be in the crosswalk during those peak times when the signal is turned off. This could cause vehicles to collide with pedestrians during their green phase. Enhancements 1. Reconstruct the non-compliant wheelchair ramps to be ADA/MAAB-compliant including detectable warning panels as to not restrict handicapped pedestrians from using the sidewalks and crosswalks. 2. Crosswalks at this intersection should be repainted using the standard ladder crosswalk pavement marking style to increase visibility of the crossings. 3. Update the timing for the pedestrian FDW clearance to meet MUTCD compliance to avoid the possibility of pedestrians still crossing the intersection during an opposing vehicle green phase. Safety Issue #4. Substandard Signal Equipment and Phasing Observations It was noted that the electrical cables for the signal heads are old and damaged at this intersection which has led to equipment failures in the past. The loop detectors are not currently operational at this intersection. At the time of the RSA, a video detection system was in use at this intersection for actuation, which occasionally malfunctions due to lowangle solar glare in the winter. The video detection system is meant to be temporary until the loop detector system is repaired. It was noted that long queues are created when the railroad preemption is activated at the intersection that is 1000 feet north of the Route 38 and Route 62 intersection. During the peak periods of the day, those long queues back up into the Route 38 and Route 62 intersection which could increase the potential for rear ends and sideswipes crashes. The signal heads are on span wires with no backplates or retroreflective stripes. It was noted during the RSA that it is sometimes difficult to see the signal heads due to solar glare. When drivers are unable to see signal heads there is a greater risk that they will operate erratically and cause any type of collision. It was suggested that if Route 62 ran concurrently instead of split phasing, it would lower queues and therefore lower the potential for rear-ends and sideswipes crashes. Enhancements 1. Evaluate the quality of the electrical cables for the signal heads and replace if necessary to ensure that equipment will function properly. Page 12

16 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates 2. Consider the feasibility of installing mast arms instead of the span wire to increase visibility of the signal heads. Installing the signal heads on mast arms will also ensure that the signals do not move when there are high winds. 3. Install backplates and retroreflective stripes for all signal heads to improve signal head visibility. 4. Evaluate whether Route 62 can have concurrent phasing instead of split phasing to avoid long queues. 5. Repair malfunctioning loop detectors and remove existing video detection system. Safety Issue #5. Poor/Insufficient Signage and Wayfinding Observations Travelling northbound along Route 38 approaching this intersection, the guide sign for Route 62 is blocked due to the proximity of the adjacent building in the southeast corner of the intersection. North of the Route 38 and Route 62 intersection there is a left lane ends sign even though the left lane has already ended and the northbound direction only has one lane. There is also no accompanying sign to the flashing yellow arrow at this intersection. This may lead to driver confusion as to what to do when given the flashing yellow arrow. Improper signage can lead to driver confusion which, as said before, can often cause drivers to operate erratically and create crashes. It was observed that vehicles were parked along the east side of the north leg of the intersection. However, there were no crashes that resulted because of parked cars on that section of the intersection. Enhancements 1. Relocate the guide sign for Route 62 northbound so that it is not blocked by the building to avoid driver confusion 2. Remove the unnecessary left lane ends sign north of the intersection to avoid driver confusion 3. Add the left turn yield on flashing yellow arrow sign (R10-12a) to the northbound Route 38 approach to avoid driver confusion when taking a left turn. 4. Evaluate the feasibility of restricting parking along the east side of the north leg of the intersection to provide safe turning movements for right turns from the eastbound of Church Street on to northbound of Main Street. This will also avoid possible collisions with parked vehicles. Page 13

17 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Safety Issue #6. Poor Sight Distances Observations For the Burlington Avenue bridge to connect to the Route 62 and Route 38 intersection, the vertical geometry resulted in a plateau at the center of the intersection. This geometry makes it difficult to see cars travelling in the opposite direction when approaching the intersection from the north or south. Of the six angle crashes within intersection, three of the crashes were reported in which drivers spoke of not being able to see the other vehicle until it was too late, due to the intersection elevation being above that of three of its approaches. Enhancements 1. Evaluate the feasibility of re-grading the approaches for this intersection to provide adequate sight distances. 2. Evaluate the feasibility of providing protected only left turn phasing on Route 38 northbound and southbound at this intersection. This would require providing an exclusive left-turn lane along the Route 38 southbound approach. However, it would lower the potential of crash when vehicles are making a left turn within the intersection. Page 14

18 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Audit Observations and Potential Safety Enhancements: Route 38 (Main Street) at Route 129 (Lowell Street) In conducting the Route 38 Road Safety Audit on Thursday, January 26, 2017, the safety issues that were identified at the intersection of Route 38 (Main Street) at Route 129 (Lowell Street) include: Faded or improper pavement markings Non-compliant/substandard pedestrian accommodations Substandard signal equipment and phasing Poor/insufficient signage and wayfinding Ineffective drainage Proper delegation of work Many of these issues can or need to be addressed by long term solutions, but some short-term improvements were also identified. The following paragraphs describe the issues at and possible actions for this intersection. The identified issues by the RSA team have some similarities and commonalities and consequently, were grouped into major categories. Safety Issue #1. Faded or Improper Pavement Markings Observations It was noted that vehicles turning left from Main Street southbound to Lowell Street eastbound do not make the turn correctly and often drive over the scored concrete median between the two directions on Lowell Street. Crash #27 occurred because a vehicle took this left turn too sharply and collided head-on with a queued vehicle on westbound Lowell Street. It was noted that the pavement markings at this intersection were fading. When pavement markings are not visible, the possibility of driver confusion is increased. Enhancements 1. Install dotted lane lines within the intersection to guide left turning vehicles into Lowell Street and decrease driver confusion. 2. Repaint faded markings and consider constant maintenance to sustain good visibility for the markings. Page 15

19 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Safety Issue #2. Non-Compliant/Substandard Pedestrian Accommodations Observations There were no pedestrian related crashes at this intersection. At this intersection, crosswalks are provided for the northern and eastern legs, however they are not the standard ladder style, which is more visible than the existing 12 white lines on either side of the walk area. Since higher pedestrian volumes are expected in commercial zones it is important to have the crosswalks as visible as possible to avoid vehicle/pedestrian crashes. The two wheelchair ramps in the northeastern corner are also missing detectable warning panels. It was noted that the vehicles parking at the Route 16 Auto Brokers encroach on the sidewalk creating an obstruction for pedestrians. The sidewalk on the northbound side of Main Street just north of the intersection with Lowell Street has tree grates within it that resulted in less than the ADA requirement of three feet of sidewalk clearance. Clearances of less than three feet do not accommodate wheelchair bond pedestrians. It was noted that a No parking anytime sign and a tree grate were so close to one another in front of Z & S Gas Station that it limits access for wheelchairs on the sidewalk. Enhancements 1. Add detectable warning panels to the wheelchair ramps that do not have them to better accommodate handicapped pedestrians. 2. Increase enforcement from local police to make sure that parked vehicles are not obstructing the sidewalk to ensure pedestrian safety. 3. Reconstruct sidewalk to provide at least three feet of clearance at tree grates to improve pedestrian safety. 4. Crosswalks at this intersection should be repainted using the standard ladder crosswalk pavement marking style to increase visibility of the crossings. 5. Relocate no parking anytime near the tree grate in front of the Z & S Gas Station so that there is at least 3 feet of clearance on the sidewalk next to it and still effectively displays where the parking is restricted. Page 16

20 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Safety Issue #3. Substandard Signal Equipment and Phasing Observations A flashing yellow arrow was installed approximately a year ago for the southbound left turn. However, drivers taking left turns from Main Street southbound onto Lowell Street sometimes fail to yield to drivers travelling along Main Street northbound. Three crashes occurred from due to left turn vehicles not yielding to on-coming traffic at this location. The 5-section signal head backplate for the Lowell Street approach is damaged. It was noted that the backplates of the signal heads at this intersection are lacking yellow retroreflective borders and that sun glare is an issue during winter and fall. When drivers are unable to see signal heads correctly there is a greater risk that they will operate erratically and cause any type of collision. Image 4: Damaged backplate, missing retroreflective border, and ineffective No Turn on Red sign at the intersection of Main Street and Route 129 Page 17

21 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Enhancements 1. Evaluate the feasibility of providing protected only left-turn phasing for drivers turning left from Main Street southbound onto Lowell Street to avoid crashes between those left-turning vehicles and northbound vehicles on Main Street. 2. Replace or repair the damaged backplates at this intersection to improve visibility of the signal heads. 3. Add retroreflective borders to the backplates to enhance visibility of the signals heads. Safety Issue #4. Poor/Insufficient Signage and Wayfinding Observations During the site visit, drivers were observed not obeying the No Turn on Red sign for the right turn from Route 129 onto Main Street northbound. This creates a higher possibility of angle crashes due to northbound Main Street vehicles colliding with the vehicles who just took a right turn on red. Enhancements 1. Consider replacing the No Turn on Red sign with a pictorial legend (R10-11) sign, moving to a more prominent location on the mast arm, or increasing enforcement. Safety Issue #5. Ineffective Drainage Observations There is a low point at three of the four wheelchair ramps which results in ponding. Page 18

22 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Enhancements 1. Evaluate the feasibility and effectiveness of re-grading the wheelchair ramps and pavement and or sidewalk around the ramps to avoid ponding and wet roadway related crashes such as hydroplaning. Image 5: Ponding at Wheelchair Ramps at the intersection of Main Street and Route 129 Safety Issue #6. Proper Delegation of Work Observations It was noted that it is the property owners obligation to remove snow from the sidewalks. If snow is blocking the sidewalk, pedestrians may walk in the road which could lead to a pedestrian/vehicle collision. Enhancements 1. The Town of Wilmington should notify property owners along Route 38 that it is their responsibility to remove snow from sidewalks to ensure pedestrian safety. Page 19

23 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Audit Observations and Potential Safety Enhancements: Route 38 (Main Street) at Cross Street/Butters Row In conducting the Route 38 Road Safety Audit Thursday, January 26, 2017, the safety issues that were identified at the intersection of Route 38 (Main Street) at Cross Street/Butters Row include: Intersection geometry deficiencies Non-compliant/substandard pedestrian accommodations Many of these issues can or need to be addressed by long term solutions, but some short-term improvements were also identified. The following paragraphs describe the issues at and possible actions for this intersection. The identified issues by the RSA team have some similarities and commonalities and consequently, were grouped into major categories. Safety Issue #1. Intersection Geometry Deficiencies Observations This intersection has major geometric deficiencies. The skewed Cross Street approach makes it challenging to reach Butters Row from Cross Street or Cross Street from Butters Row. Since the intersection is at a higher grade than all legs, it is difficult to view oncoming cars when approaching the intersection. Sight distances from Cross Street are especially poor. The right turn is very sharp and vegetation on the east side of Main Street, north of this intersection, restricts sight distance for vehicles exiting Cross Street. This vegetation also blocks the sight of vehicles exiting Cross Street for vehicles travelling southbound on Main Street approaching the intersection. Of the 16 crashes reported at this intersection between 2013 and 2015, six crashes occurred when a vehicle attempted to exit Cross Street and collided with a vehicle traveling southbound on Main Street. To the south of the intersection, large boulders are lined along the east side of Route 38 blocking the sight of approaching northbound vehicles. (Because the intersection is at a higher grade) Of the 16 crashes at this intersection between 2013 and 2015, seven crashes occurred when a vehicle attempted to exit Cross Street. It was also noted that the stop bar for Butters Row is too far back from the intersection (approx. 12 feet) which may have contributed to the four crashes that occurred when a vehicle exited Butters Row and was struck by a vehicle travelling on Main Street. At least two additional rear-end crashes reported on Main Street at this location involved drivers stopping to let vehicles cross from and to the minor legs. Page 20

24 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Enhancements 1. Consider realigning Cross Street to form a perpendicular intersection with Main Street. This would create better sight distances for drivers exiting Cross Street and for drivers on Main Street who need to see if anyone is exiting Cross Street. 2. Consider signalizing the intersection, which would lessen the confusion at the intersection when entering from Butters Row or Cross Street. 3. Consider implementing a roundabout at the intersection which would lower the number of conflict points, lower crashes, and lower the severity of crashes that do occur. 4. Consider installing channelizing lanes at Cross Street, which would lower the confusion when entering the intersection, as well as increase sight distances, and make it easier to be seen by other vehicles. 5. Evaluate the feasibility of re-grading the approaches to the Main Street at Cross Street/Butters Row intersection, or realigning the Cross Street and Butters Row approaches which would also improve sight distances within the intersection. 6. Trim overhanging vegetation on the east side of Main Street north of this intersection. If Cross Street is not redesigned to be perpendicular to Main Street this would still help to create better sight distances for drivers exiting Cross Street and for drivers on Main Street who need see to if anyone is exiting Cross Street. 7. Coordinate with the property owner to consider relocating or replacing the boulders that restrict the sight distance of drivers exiting Cross Street looking south, or replacing the boulders with shorter ornamentation that would not block sight distances. 8. Consider the feasibility of moving the Butters Row stop bar closer to the intersection to improve sight distances from Butters Row. Turning movements of a northbound vehicle on Main Street turning left on to Butters Row will need to be considered. Image 6: Grading and rocks block sight distances from Cross Street (on right) 9. Consider making Butters Row a one-way street to lower the number of conflict points within the intersection, which would decrease the possibility of angle collisions since vehicles will not be entering the intersection from Butters Row.

25 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Safety Issue #2. Non-Compliant/Substandard Pedestrian Accommodations Observations With the new public park (Yentile Farm) near this intersection, it is anticipated that there will be significantly more pedestrian activity than there is now. Even though there are no pedestrian related crashes, it was noted that there are no sidewalks or crosswalks at the intersection of Main Street with Cross Street/Butters Row Enhancements 1. Consider the feasibility of adding sidewalks at this intersection to increase pedestrian safety. 2. Due to the anticipated increase in pedestrian activity created by the adjacent Yentile Farm, evaluate the feasibility of installing pedestrian signals at this intersection. 3. Consider installing marked crosswalks with pedestrian crossing warning signage and rectangular rapid flashing beacons (RRFBs) across Route 38 (Main Street) at this intersection with pedestrian warning signs and diagonal arrow when the park opens. Page 22

26 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Audit Observations and Potential Safety Enhancements: Route 38 (Main Street) at Eames Street In conducting the Route 38 Road Safety Audit Thursday, January 26, 2017, the safety issues that were identified at the intersection of Route 38 (Main Street) at Eames Street include: Intersection geometry deficiencies Non-compliant/substandard pedestrian accommodations Insufficient lighting Ineffective drainage Many of these issues can or need to be addressed by long term solutions, but some short-term improvements were also identified. The following paragraphs describe the issues at and possible actions for this intersection. The identified issues by the RSA team have some similarities and commonalities and consequently, were grouped into major categories. Safety Issue #1. Intersection Geometry Deficiencies Observations Due to the skewed approach, taking right turns from Eames Street westbound onto Main Street northbound or taking left turns from southbound Main Street to eastbound Eames Street are difficult for tractor trailers. (See crash #7) Drivers often encroach upon the opposing lane on Main Street to maneuver either turn, which poses a serious safety risk if a vehicle is travelling in the opposite direction. Additionally, an increase in tractor trailer traffic is expected on Eames Street due to a new warehouse. It is very difficult to see vehicles travelling southbound on Main Street when exiting Eames Street due to a horizontal curve just north of the intersection. Of the 17 crashes at this intersection between 2013 and 2015, two crashes occurred when a vehicle attempted to exit Eames Street and collided with a vehicle traveling southbound on Main Street. Five crashes involved vehicles exiting Eames Street colliding with northbound vehicles. Enhancements 1. Consider realigning Eames Street to form a perpendicular intersection with Main Street. This would make the right turn out of Eames Street or the left turn into Eames Street much easier. 2. Consider creating a right-turn lane for the Eames Street westbound approach. This would improve the right turn out of Eames Street 3. Consider installing flashing beacons at the intersection to highlight the presence of a side street and entering traffic. Page 23

27 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates 4. Evaluate the feasibility of constructing medians or channelizing islands which lowers the confusion when entering the intersection, as well as increases sight distances, and makes it easier to be seen by other vehicles. Safety Issue #2. Non-Compliant/Substandard Pedestrian Accommodations Observations Even though there are no pedestrian related crashes, it was noted that there are no sidewalks or crosswalks at the intersection of Main Street with Eames Street. Enhancements 1. Consider the feasibility of adding sidewalks at this intersection to increase pedestrian safety. 2. Consider installing marked crosswalks with pedestrian crossing warning signage and rectangular rapid flashing beacons (RRFBs) across Main Street at this intersection with pedestrian warning signs and diagonal arrow. 3. If sidewalks and crosswalks are installed, also consider installing a High-intensity Activated Crosswalk beacon (HAWK) or a pedestrian signal if it meets the signal warrant. Image 7: No sidewalks or crosswalks are provided at the Eames Street and Main Street intersection Page 24

28 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Safety Issue #3. Insufficient Lighting Observations There is poor overhead lighting at this intersection which could have contributed to the relatively high amount of dusk crashes at this location. Of the 17 crashes at this intersection between 2013 and 2015, four crashes occurred when at night, or during dusk or dawn. Enhancements 1. Evaluate the feasibility of improving the existing lighting (possibly LED) or installing additional overhead lighting at this intersection. Safety Issue #4. Ineffective drainage Observations The catch basin at the corner between the north leg of Main Street and Eames Street is too far from the curb and is slightly higher than the surrounding pavement. Thus, the catch basin is not catching sufficient runoff, resulting in the erosion of the edge of pavement. Of the 17 crashes at this intersection between 2013 and 2015, 10 crashes occurred during wet or icy road conditions. Enhancements 1. Evaluate the feasibility of relocating the catch basin to improve drainage. Image 8: Catch basin is not next to the curb at the corner of Eames Street with Route 38. Page 25

29 Road Safety Audit Route 38 from Route 62 to Woburn Town Line, Wilmington, MA Prepared by Green International Affiliates Summary of Road Safety Audit Based on the audit team members review of observations and discussions, issues and possible solutions were identified that could help reduce safety risks along the Route 38 (Main Street) between Route 62 (Burlington Avenue/Church Street) and the Woburn Table 2 defines estimated safety payout, time frame, cost, and responsibility. The issues and possible solutions from the previous sections are summarized in Table 3. These estimates are based on engineering judgement and typical construction practices. Safety Payoff: the enhancement could reduce the number of crashes along the corridor by a low (<3), medium (3-7), or high (>7). Time frame: the enhancement can be completed within a time frame of short-term (<1 year), mid-term (1-3 years), or long-term (>3 years). Cost: cost is estimated to be within one of three categories of cost of low ($10,000), medium ($10,001- $50,000) or high (>$50,000). Responsibility: which entity or organization will be responsible for completing the work. Table 2: Estimated Time Frame and Costs Breakdown Time Frame Costs Short-Term <1 Year Low <$10,000 Mid-Term 1-3 Years Medium $10,001-$50,000 Long-Term >3 Years High >$50,000 Page 26
