Launched by Mayor Joseph Curtatone in September 2017, Vision Zero Somerville reaffirms the City's commitment to multi-modal road safety. The initiative takes a multi-department, data-driven approach to improving safety for all road users, whether on bicycles or on foot, in vehicles, or aboard public transit.



  • Increased road safety awareness across municipal government departments
  • Lowered speed limits citywide, with the additional goal of adding 65 new 20 mph safety zones near schools, senior centers, hospitals, and parks
  • Improved infrastructure, including:
    • Parking-protected bike lanes on Washington Street
    • A mid-block crosswalk and flashing beacon at Union Square
    • A separated bike lane being added to Beacon Street during its reconstruction


Somerville's Vision Zero work will need to center around aligning their transportation systems with other community-driven priorities, and continuing to advocate for Vision Zero within the context of large state-led projects like the Green Line Extension.


What's Next

Somerville is using data-driven technical planning and community input to create a plan of one-, three-, and five-year actionable goals around engineering, education, and enforcement efforts. They will release their first Action Plan in 2020.
