    12th Avenue Slow Street Evaluation 

    Following the SFMTA Board’s approval of 12th Avenue, the SFMTA Project team collected additional data analysis to assess how the street is performing against the Slow Streets Program targets

    • Vehicle speeds at or below 15 mph 
    • Vehicle volumes less than 1,000 per day 

    12th Avenue did meet Program speed targets but did not meet Program volume targets

    For additional information on how this street compares to others in the Slow Streets program, or for overall program findings, please see the 2023 Evaluation Report.

    Next Steps

    12th Avenue did not meet program speed targets but did meet program volume targets. The Slow Streets program team will:

    • Consider additional traffic calming tools and prepare a design to slow vehicle traffic. The design will be posted on this page and a public hearing will provide an opportunity for feedback.
    • Continue to monitor vehicle volumes on this street.
