3 Background The Neponset Street Rotary, also known as Pendergast Circle, which is the convergence of Neponset Street, Nahatan Street, and the US Route 1 on- and off-ramps, was identified as a high crash location in the Metropolitan Area Planning Council (MAPC) based on the 2011 Highway Safety Improvement Program (HSIP) cluster data. Improvements at this intersection, to be constructed as part of the off-site mitigation related to the University Station mixed-use transit-oriented development to be located off of University Avenue in Westwood, are currently under review by the MassDOT Highway Division at the 25% Design Level. The MassDOT Highway Division Traffic and Safety Engineering 25% Design Submission Guidelines require a Road Safety Audit (RSA) be performed for all project-related high crash locations to identify safety issues and enhancements that may be implemented in conjunction with the University Station off-site mitigation project, as well as other measures that could be programmed for implementation by others in the mid-term or long-term timeframes. Project Data The RSA for the subject location was conducted on September 8, 2014 at the Westwood Municipal Building. The RSA Meeting Agenda is provided in Appendix A. Participating audit team members and their affiliation are listed in Table 1; team member contact information is provided in Appendix B. For this modified RSA, team members were encouraged to visit the location prior to the meeting to observe operations and evaluate potential safety issues, using MassDOT s Safety Review Prompt list for guidance. At the meeting, team members were provided with an aerial photograph of the location, and a collision diagram, summary table, and various bar charts analyzing motor vehicle crashes reported within the three year review period ( ). This material was reviewed by the team at the meeting in conjunction with street level views afforded by Google Earth. Table 1.

4 Motor vehicle crash data was provided by the Norwood Police Department for the most recent three year review period available ( ). The data provided includes 68 reported crashes, with three (4%) resulting in personal injury, and no reported fatalities. The vast majority (87%) of the crashes were rear-end crashes, with 74% of those occurring on the Route 1 off-ramps; five (7%) were crashes with fixed objects, three (4%) were sideswipe crashes, and one (1.5%) was an angle crash. Fifteen (22%) of the crashes occurred on wet pavement and two (3%) in icy conditions. Most of the crashes (47%) occurred during peak evening commuting hours (2 pm to 6 pm). Project Location and Description The Neponset Street Rotary is a single-lane rotary under MassDOT Highway Division jurisdiction, which provides for vehicle movements between Neponset Street, Nahatan Street, and the Route 1 on- and offramps. The overall diameter of the rotary is approximately 500 feet and the circulating roadway is typically about 40 feet wide, currently striped with a 2 foot inside shoulder and approximate 28 foot circulating lane. Each intersecting roadway enters and exits the rotary at an angle of approximately 20 to 40 degrees. A sidewalk currently traverses the rotary, beginning on the north side of Neponset Street, then continuing counterclockwise around the rotary to the north side of Nahatan Street. Neponset Street Neponset Street is a two-lane urban principal arterial under Town of Norwood jurisdiction to a point approximately 300 feet from the rotary, where it becomes MassDOT Highway Division jurisdiction. The posted speed limit on Neponset Street is 30 miles per hour (mph). Nahatan Street Nahatan Street, which intersects the west side of the rotary, is a two-lane urban minor arterial under Town of Norwood jurisdiction to a point approximately 200 feet from the rotary, where it becomes MassDOT Highway Division jurisdiction. The posted speed limit along Nahatan Street is 30 mph. Route 1 Ramps The Route 1 on- and off-ramps intersect the rotary from the north and south, forming an elongated diamond interchange. The ramps are each single lane ramps, approximately 22 feet wide, with crosswalks across the northbound on- and southbound off-ramps on the northern side of the rotary. A locus map and aerial photograph of the existing conditions are provided as Figure 1 and 2, respectively. Page 2

7 Audit Observations & Potential Safety Enhancements Observations: Geometry The acute angle of approach on each leg allows for high entry speeds and requires drivers to look far left over their shoulder for a gap in circulating traffic. Drivers may assume the vehicle in front has entered the rotary and then advance without looking ahead. This condition, combined with peak hour congestion, likely contributes to the high number of rear-end crashes reported. The large radius of the rotary and wide circulating lane also allow for high circulating speeds. This condition decreases the perceived gaps available for entering vehicles. This may contribute to rear-end crashes on entry if drivers are indecisive and stop short after beginning to proceed. An audit member commented that the success of a rotary is dependent on entering speeds similar to circulating traffic, good visibility, and available gaps; none of which exist at this location during peak hours. Queues An audit member commented that the Nahatan Street and Route 1 southbound off-ramp approaches experience queues in the afternoon peak hours. It was also noted that Neponset Street southbound queues during the same period from the I-95 interchange up to one-quarter of the way around the rotary (over a mile). Both of these conditions increase the difficulty of entering the rotary and increases delay and frustration which, in turn, contributes to various crash types. Pedestrian Accommodation Visibility to and recognition of the crosswalk on the Route 1 northbound on-ramp was raised as a concern. The Town emphasized that their priority is safe pedestrian crossings. However, there were no reported pedestrian crashes during the threeyear review period. Page 5

8 The width of the existing sidewalk on the bridge over Route 1, on the north side of the rotary, was deemed to be too narrow for ease of maintenance by the Town, which hinders winter maintenance. Visibility to/from Route 1 Ramps It was noted that visibility of vehicles entering Route 1 southbound from the rotary on-ramp is poor due to the vertical difference in roadways, the horizontal curve on Route 1 approaching the ramp, and exacerbated by vegetation between the ramp and mainline Route 1. This issue is further exacerbated by the fact that there is not a dedicated acceleration lane for vehicles entering Route 1. It should be noted that any reported crashes in this area may not have been included in the collected data, as the study area focused on the rotary itself and the immediate entry and exit points. Drivers on Route 1 southbound, north of the rotary, were observed to switch lanes at the last minute to access the ramp to the rotary. Advance visibility to the ramp is sometimes restricted by the Nissan auto dealer parking vehicles in the grass shoulder adjacent to Route 1. This condition is exacerbated by limited/confusing guide signs; an existing D6 guide sign reads Norwood Center/Canton/Next Right where the next right is actually the Nissan driveway. It should be noted that any reported crashes in this area may not have been included in the collected data, as the study area focused on the rotary itself and the immediate entry and exit points. Visibility of the rotary circulating traffic is limited upon approach from Route 1, both northbound and southbound, because of the bridge railing/fence and vegetation. Signing It was noted that the existing merge sign (W4-1L) on the Route 1 northbound off-ramp incorrectly indicates that ramp traffic has priority and may be confusing to drivers, possibly contributing to rearend crashes. In addition to the limited/confusing guide signs on Route 1 southbound approaching the rotary (noted above), advance guide signage approaching the rotary on Route 1 northbound is also inadequate. There is a large sign at the exit point, but the lack of advance signage means that drivers may not know where the off-ramp leads and could cause last minute lane changes. It should be noted that any reported crashes in this area may not have been included in the collected data, as the study area focused on the rotary itself and the immediate entry and exit points. Page 6

9 Pavement Markings It was suggested that it is not clear where the desired yield point is on each approach due to the lack of pavement markings, contributing to drivers creeping into the rotary before committing to entering the circulating traffic. This may increase the likelihood of rear-end crashes on entry and could be the cause of angle crashes within the circulating the roadway if an entering vehicle creeps too far. Route 1 Northbound Ramp Termini A number of concerns were raised concerning the Route 1 northbound on-ramp. MassDOT indicated that the raised gore area was extended at some point to restrict access to a commercial driveway. The remaining merge area appears to be insufficient for acceleration onto Route 1, and the angle of entry makes it appear as though the ramp has a dedicated lane entering Route 1. Also, the desired yield point is not well defined. It should be noted that any reported crashes in this area may not have been included in the collected data, as the study area focused on the rotary itself and the immediate entry and exit points. The Route 1 northbound off-ramp deceleration area was also raised as a possible safety issue. The deceleration taper from Route 1 to the off-ramp is not well defined, given the proximity of the East Cross Street entry to Route 1 and the provision of an acceleration area for that roadway; a short weave conflict is created in this area. This may impact though traffic on Route 1 if vehicles departing to the rotary begin deceleration within the Route 1 through lane. A similar situation is exists between the Route 1 southbound on-ramp and East Cross Street on the west side of Route 1. Again, it should be noted that any reported crashes in these areas may not have been included in the collected data, as the study area focused on the rotary itself and the immediate entry and exit points. Page 7

10 Potential Enhancements: 1. Realign approaches to the rotary to reduce the angle of entry (MassDOT s preferred maximum is 70 degrees) to improve visibility of circulating traffic without diverting attention from vehicles immediately in front on entry and to reduce the occurrence of rear end crashes. 2. Install gore markings to visually narrow and better define approaches to the rotary, reducing entry speeds. 3. Install pavement markings to better define and narrow the circulating roadway, reinforcing the intent of single-lane circulation and reducing sideswipe and angle crashes. 4. Restripe crosswalks for greater emphasis (ladder or continental style) to better alert drivers to crossings. 5. Install beacons (preferably pushbutton actuated) for the crosswalks on the Route 1 northbound on-ramp and southbound off-ramp to alert drivers and provide improved visibility/recognition of crossings. 6. Widen sidewalk across bridge over Route 1 on the north side of the rotary to improve pedestrian accessibility and maintenance access for the Town. 7. Install merge warning signs on the Route 1 southbound on-ramp (W4-5) and on Route 1 southbound (W4-1R) approaching the ramp to provide advance notice of required merge condition entering Route Clear vegetation between the Route 1 southbound on-ramp and Route 1 mainline to improve visibility of oncoming traffic for vehicles merging onto Route 1 southbound from the rotary. 9. Widen Route 1 southbound to provide additional acceleration lane length for traffic entering from the rotary. 10. Install State Highway - No Parking signs in the vicinity of the Nissan dealership on Route 1 southbound. 11. Install guide sign on Route 1 southbound at exit point to rotary and replace existing advance guide sign to state Second Right rather than Next Right. 12. Clear vegetation obstructing view of circulating traffic from the Route 1 northbound and southbound off-ramp approaches. 13. Replace merge warning sign on Route 1 northbound off-ramp with sign indicating correct priority to clarify that circulating traffic within the rotary will have the right of way. 14. Install advance guide sign (D6) on Route 1 northbound approaching the rotary. Page 8

11 15. Install YIELD lines and YIELD pavement markings on each approach to the rotary to emphasize desired yield point on entry. However, MassDOT District 5 Traffic Operations has expressed a maintenance concern with the YIELD pavement markings and requested that they not be applied. 16. Install larger YIELD sign and YIELD line on the Route 1 northbound on-ramp to better define the desired yield point. However MassDOT District 5 Traffic Operations has indicated that larger signs are not warranted, as the existing sign is of the standard size used on State Highway, and there is an existing Yield Ahead sign as well. It should also be noted that a yield line is not allowed at this location per Section 3B.16 of the Massachusetts Amendments to the 2009 MUTCD. 17. Review Route 1 northbound and southbound on-ramp acceleration/merge area and, if warranted, widen to provide adequate transition. 18. Review acceleration/deceleration areas on Route 1 northbound and southbound at East Cross Street and install wide dotted lane lines between East Cross Street and the ramps to/from the rotary per MUTCD Figure 3B-10E. 19. Replace all faded signs within the rotary and on rotary approaches. 20. Evaluate right-turn bypass lanes on all approaches to the rotary and install on approaches determined to be warranted based on evaluation. This could reduce congestion and associated crashes, particularly rear ends. 21. Review alternatives and construct improvements along Neponset Street, south of the rotary, to reduce congestion and associated queues extending into the rotary. 22. As part of future reconstruction efforts, evaluate reconfiguration of rotary for alternative form of traffic control, such as traffic signals or roundabouts. Page 9

12 Summary of Road Safety Audit Potential safety enhancements that were discussed during the RSA meeting and described in the previous section are summarized in Table 2. For each potential enhancement, an estimate of the safety benefit ( payoff ), approximate timeframe to implement, and cost are noted; the responsible party recommended to implement the enhancement is also identified. Safety payoff estimates are qualitative and categorized as low (<30%), medium (31% to 70%), or high (>71%). The time frame to implement each enhancement is categorized as short-term (<1 year), mid-term (1 to 3 years), or long- term (>3 years). The cost estimates are categorized as low (<$10,000), medium ($10,001 to $50,000), or high (>$50,001). Enhancements where the developer is identified as the responsible agency and marked with an asterisk have already been incorporated into the 25% Design Plans for improvements at this intersection, to be constructed as part of the off-site mitigation related to the University Station mixed-use transit-oriented development to be located off of University Avenue in Westwood, which are currently under review by the MassDOT Highway Division.
