San Francisco's Tenderloin Neighborhood

The Tenderloin is disproportionately impacted by severe and fatal collisions, especially those caused by high vehicle speeds. Almost all streets within the Tenderloin are on San Francisco’s High-Injury Network. Building on past neighborhood-wide efforts, the Tenderloin Traffic Safety Improvements project will reduce the speed limits of many streets from 25 to 20 miles per hour and restrict turns on red at 54 intersections. Studies show that lowering speeds greatly reduces the severity of a collision and restricting turns on red decreases the number of conflicts and injuries between people driving and walking. 

Project/Study Partners

This project is funded by the Transportation Authority’s Neighborhood Program and led by SFMTA.
