ALT Crash data in Somerville indicate that a small number of our streets and intersections experience a disproportionately high share of our crashes. These streets and intersections are categorized as the “High Crash Network” and help us to prioritize resources. Our most recent data from 2018-2022 finds that some of our high crash locations include major intersections along state roads like McGrath Highway, Mystic Avenue, and Alewife Brook Parkway, in addition to some of our high-volume streets like Broadway and Somerville Avenue.
