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.

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 the Top 200 Crash Locations in Massachusetts.

NMCOG staff produce a report detailing the top 100 crash locations for the region which enables Northern Middlesex communities to be eligible for Highway Safety Improvement Program (HSIP) funds to implement improvements at high crash intersections.  As part of this program, NMCOG works with its communities and MassDOT to conduct Road Safety Audits (RSAs) 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:

  • South Street at Salem Street in Tewksbury (ongoing)

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  Moving Ahead for Progress in the 21st Century Act (MAP-21).
