RE: FFY 2017 Addressing Safety, Mobility, and Access on Subregional Priority Roadways: Selection of Study Locations
During the MPO’s outreach for development of the Unified Planning Work Program (UPWP) and Long-Range Transportation Plan (LRTP), Metropolitan Area Planning Council (MAPC) subregional groups and other entities submit comments and identify transportation problems and issues that concern them. Often, these issues are related to bottlenecks, safety, or lack of safe or convenient access for abutters along roadway corridors. They can affect not only mobility and safety along a roadway and its side streets, but also a community’s quality of life, including economic development, and air quality.
To address these concerns, this study was included in the UPWP for federal fiscal year 20171 and a work program was approved on December 1, 2016. The purpose of this study is to identify roadway segments in the MPO region that are of concern to subregional groups but that have not been identified in the LRTP regional needs assessment.2
The study emphasizes issues identified by the relevant subregional groups, along with recommendations to address the identified issues. In addition to topics about mobility, safety, and access, it includes bicycle and pedestrian transportation, transit feasibility, and other subjects raised by subregional groups.
This memorandum discusses the procedure used to select roadways for the study, including selection criteria; the roadway corridor that was chosen for study; and a summary.
Selection of the study location comprised three steps: 1) identifying potential roadways, 2) developing selection criteria, and 3) rating potential roadways.
MPO staff identified potential study roadways through various sources, including:
MPO staff then assembled detailed data for these roadways, including:
Locations with projects that currently are under construction, in design, under study, or programmed in the TIP were excluded from further consideration. After the exclusion, MPO staff identified 25 potential roadway segments in the region. Table 1 presents data assembled for each roadway segment and indicates municipality, MAPC subregion, MassDOT district office, jurisdiction, length, functional class, average daily traffic, overall crash rates, bicycle/pedestrian crashes per mile, Highway Safety Improvement Program (HSIP)-eligible crash clusters,3 and any relevant studies or projects. It also cites results of applying the selection criteria, and priority rating. Roadway segments are sorted by score, MassDOT District, and roadway name.
MPO staff examined roadway locations more closely by applying five criteria: safety conditions, multimodal significance, subregional priority, implementation potential, and regional equity per the scoring system below.
Roadway segments with a score of five points or less were rated as low priority. Roadway segments with a score of six-to-seven points were rated medium priority. Roadway segments with a score of eight-or-more points were rated high priority. Among the 25 potential locations, MPO staff identified three as high priority:
Staff also evaluated the pedestrian accommodation and safety improvement needs for the three locations by applying the Pedestrian Report Card Assessment that the MPO recently developed.4 All three locations highly qualify for pedestrian accommodation or safety improvement requirements. Appendix A contains detailed results of the assessments.
MPO staff recommend Route 1A from Plainville town line to Route 140 in Wrentham for this study cycle, based on the following considerations:
Figure 1 shows the locations of this selected and the previously studied corridors in the region. The selected roadway is about 3.1 miles long. It is classified as an urban minor arterial and is mainly a two-lane roadway except a four-lane section in the vicinity of Wrentham Village Premium Outlets and Interstate 495 Interchange. The roadway has no dedicated bicycle accommodation. Sidewalks exist on both sides only in the town center area and on one side only in the section west of Route 121. All of its sections are under MassDOT District 5’s jurisdiction. Several sections along the roadway are under consideration for development or redevelopment. This study would be timely for examining the corridor’s safety and operational issues, exploring multimodal opportunities, and connecting the corridor’s various projects in a consistent and cohesive approach.
Route 1A is one of the most significant commuter corridors in the South West Advisory Planning Committee (SWAP) subregion. The selected Route 1A section meets the objectives of this study, especially in supporting the transportation improvement priorities of the SWAP subregion.
MPO staff will submit this proposal to the MPO for discussion and approval. If the MPO approves this selection, staff will meet with officials from Wrentham, MassDOT, and MAPC to discuss the study specifics, conduct field visits, collect data, and perform various analyses.

1 | 2 | 2 | 3 | 1 | 9 | High | Both MassDOT and the Town of Wrentham strongly support this corridor study. The corridor exhibits congestion in the vicinity of the Wrentham Premium Outlets and there is potential for additional significant development in the immediate area. The corridor also includes high crash locations and lacks bicycle/pedestrian accommodations. It would be worthwhile to study the corridor and provide recommendations to the town and MassDOT prior to additional development. Recent MassDOT Project 605218 includes the corridor in scope, but does not address pedestrian and bicycle accomodation, safety, and operational improvements. |
