SFMTA Adds Traffic Calming to 141 City Sites

San Francisco's streets will get safer as the city installs traffic calming measures at 141 locations, transit officials said Monday. The San Francisco Municipal Transportation Agency announced the initiative December 9 as part of its Vision Zero commitment to eliminate traffic deaths. Officials didn't specify which neighborhoods will see changes or when work will begin. The citywide program aims to slow vehicle speeds and improve safety for people walking, biking, and driving.

Background on Traffic Calming Efforts

Traffic calming uses physical design changes to slow vehicle speeds and make streets safer for all users, according to the SFMTA. The agency adopted Vision Zero policies in 2014 to eliminate traffic deaths through engineering, enforcement, and education. Officials said the 141-location program represents a major expansion of safety efforts across San Francisco neighborhoods. Specific details about which types of measures will be used at each location weren't available by publication time.

Program Details and Scope

The initiative will bring safety improvements to 141 sites throughout the city, though officials haven't released a list of specific addresses or neighborhoods. Traffic calming typically includes speed bumps, curb extensions, raised crosswalks, and other roadway design changes that encourage slower driving. Jeffrey Tumlin, Director of Transportation at SFMTA, oversees the agency's safety programs. Cost estimates for the 141-location program weren't disclosed in the announcement. Officials said the measures are designed to create more livable streets while reducing vehicle speeds in residential areas.

Implementation Timeline

The SFMTA hasn't announced a specific timeline for implementing the traffic calming measures at the 141 locations. Officials said detailed implementation plans are still being developed. Transit agencies typically release construction schedules and location-specific details closer to the start of work. The agency didn't say whether all 141 sites will be completed simultaneously or rolled out in phases over time.
