Engineering Streets for Safety

More than 70 percent of severe and fatal collisions occur on just 12 percent of San Francisco streets. Vision Zero SF aims to tame streets with higher collision rates and prevent tragedy when people make mistakes. Engineering projects in support of Vision Zero incorporate effective safety improvements like protected bike lanes, wider sidewalks and reduced traffic speeds. The goal is to calm traffic, enhance visibility and improve the organization of our streets.

One of the first commitments to advance Vision Zero was to complete 24 priority projects in 24 months; the City surpassed that target and completed 30 priority projects in 24 months.  To maintain the momentum, a new set of priority projects have been identified although this time the list goes beyond engineering–it includes education, enforcement, evaluation and policy efforts as well.

Speed Management

In San Francisco, speeding is the leading causes of traffic deaths and severe injuries—and lowering speeds is the single most effective tool we can use to save lives.

Left Turn Traffic Calming

In 2019, 40% of traffic deaths in San Francisco were caused when drivers made left turns and didn’t see the person in the crosswalk, until it was too late.

Traffic Calming

The SFMTA’s Traffic Calming Program is a resident-driven, application-based program to address mid-block speeding on residential streets in San Francisco. The program seeks to enhance neighborhood livability by reducing the adverse impacts of vehicular traffic on residential streets and creating safer and more comfortable streets for people walking, bicycling, and driving alike.
