Questions

Somerville, MA — FAQ

Where does the Somerville, MA crash data come from?
Directly from official government open data: City of Somerville Open Data — Police Data: Crashes (Somerville Police Department, ODbL). Police-reported collisions are published on the open-data portal (typically with a short processing delay) and we re-read it every 6 hours. This is real police data, not news reports.
How many car accidents happen in Somerville, MA?
In this latest sample of 150 police-reported crashes (2026-04-21 to 2026-08-30), 57 people were injured and 0 killed. Across the whole area, Somerville, MA records thousands of reported collisions per year.
Is this map real-time?
No. The newest record the portal has published is from 2026-09-09, so treat this page as historical data rather than today's crashes. For life-threatening emergencies always call 911 — this page is informational.
What can the crash pattern explorer show?
It filters the official records from the last 365 days (up to 5,000 of the most recent) by period, severity, collision type and a circle drawn on the map, and charts them by week, weekday and hour next to a full-year monthly total from the portal's own counts. It counts recorded crashes only: without traffic volumes it cannot say how risky a street is, so it never ranks streets as safe or dangerous.
