Traffic Safety Program

NMCOG maintains a regional Traffic Safety Program established to meet the following goals:

  1. Identify intersections with safety problems;
  2. Inform local and state officials and the public of safety problem locations; and
  3. Provide technical assistance to help determine the cause of the safety problems and make recommendations for traffic safety improvements.

NMCOG staff produce an annual Regional Transportation Safety Report (2017 Edition includes crash data through 2014) detailing progress toward regional safety targets outlined in the Regional Transportation Plan.  The safety report also outlines the top 100 crash intersections in the region, outlining eligibility for Federal Highway Safety Improvement Program (HSIP) funding to implement improvements at high crash intersections.

Crash data from MassDOT and the Registry of Motor Vehicles (RMV) are used by NMCOG to locate and rank high crash intersections. The Equivalent Property Damage Only Method (EPDO) of ranking high crash locations is utilized, taking into account the total number of crashes at a location and the severity of each crash. This methodology is also currently used by MassDOT in its development of their Top 200 Crash Locations Report for Massachusetts.

As part of the safety program, NMCOG works with its communities and MassDOT to conduct Road Safety Audits (RSA) at locations of concern. The RSAs examine safety deficiencies at each location and recommend low cost improvement strategies. Road Safety Audits performed to date include:

This work is undertaken as a component of the State Highway Safety Improvement Program (HSIP) and Strategic Highway Safety Plan (SHSP) both of which are legislatively mandated through the Fixing Americas Surface Transportation (FAST) Act.
