Description: The Network Screening – Crash Based data can be used to access and visualize Massachusetts top crash locations based on intersections exceeding the predicted number of crashes. The information is based on the latest 5 years of closed geocoded crashes (2017-2021).Safety Performance Functions (SPFs), based on the specific roadway network and crash data, have been developed to determine the ranking of the intersections. For additional information and descriptions visit MassDOT SPF Development and Ranking Methodology. The data in this module only contains intersection crash results. For the methodology in determining top crash segment locations and to view the map please refer to MassDOT's Top crash locations and maps.
