Evaluation Report Summary: California Street Safety Project
California Street Safety Project Leads to Reduction in Collisions
The California Street Safety Project implemented a road diet on California Street between Arguello and Park Presidio boulevards in summer 2020 to improve safety. The street is on the city’s high-injury network and also had frequent collisions involving Muni buses due to its narrow travel lanes.
The street was converted from four travel lanes to three, with a center lane for left turns. Other improvements included intersection daylighting, continental crosswalks and more time for people walking to cross the street at traffic signals.
