Muni collisions

Monthly Muni collisions per 100,000 vehicle miles.

The Muni vehicle collision rate measures the ratio of Muni collisions to every 100,000 miles of Muni service. Measuring Muni collisions per 100,000 miles helps the San Francisco Municipal Transportation Agency (SFMTA) compare performance across different vehicles in its fleet.

Collision reporting is a key performance indicator for the SFMTA’s strategic objective to create a safer transportation experience for everyone.
