On March 21, 2016, the Cambridge City Council unanimously adopted Vision Zero. The City formed a Vision Zero Advisory Committee that includes Cambridge residents as well as representatives of local advocacy groups.



  • The City released its Vision Zero Action Plan in February 2018. 
  • In July 2017, a two-way separated bike facility was installed on Brattle Street from Eliot Street to Mason Street and a one-way separated facility was installed on Mass Ave. between Trowbridge Street and Quincy Street.
  • Cambridge also installed designated bikes lanes on Massachusetts Avenue between Beech Street and Route 16.
  • The City has implemented a number of short-term improvements in Inman Square, such as updating markings on pavements and traffic signs to make intersections safer.


The City's roll-out of 1.25 miles bike lanes in less than a year caused some contention around the public process. Local business owners and residents criticized the City’s rush and said that there was not enough outreach done before the decisions were made. As Cambridge moves forward, it will be important for the Transportation Department and City leaders to focus on developing their education, outreach, and communication strategies around Vision Zero.


What's Next

  • Long-term safety improvements will be implemented in Inman Square to create a better environment for walking, biking, and transit.
  • The City has proposed a number of safety improvement for Porter Square, the site of two fatal bike crashes in 2016.
