San Francisco supervisors authorized a resolution Tuesday urging California lawmakers to expand the city’s automated speed camera program, which currently has 33 cameras operating in the city under a state pilot. 
The board’s 10-to-1 vote on Tuesday, with District 10 Supervisor Shamann Walton voting against it, will not add cameras immediately, but formally asks the state to explore changes to the program. 
The San Francisco Municipal Transportation Agency has identified at least 80 additional high-need locations that could benefit from automated enforcement, according to a report filed with the Public Safety and Neighborhood Services Committee. 
Richard Zieman, whose son Andrew, a paraeducator, was killed in November 2021 by a speeding driver outside Sherman Elementary School on Franklin Street, told Mission Local that city officials should do more. 
“They waited for a tragedy,” Zieman said. 
Parents and school leaders had repeatedly asked the city to slow traffic on Franklin Street, where drivers barreled downhill toward the Marina, said Zieman. 
Supervisor Matt Dorsey, who introduced the resolution, has said the city’s first year of automated speed enforcement shows that the technology works. 
The SFMTA reported nearly an 80 percent reduction in drivers traveling at least 10 miles per hour over the speed limit at camera locations after the program launched in March 2025. 
San Francisco was the first city to implement the pilot authorized under Assembly Bill 645. 
The pilot, however, is capped by state law at 33 camera locations. 
Tuesday's resolution asks California lawmakers to consider allowing more, prioritizing corridors on San Francisco's High Injury Network, including Franklin Street. 
Walk San Francisco, a pedestrian advocacy group which spent roughly eight years advocating for the state legislation that created the pilot, called the resolution an important first step toward broader expansion. 
“Thirty-three cameras is nowhere near the number of cameras we need for people to realize that San Francisco is a safe-speed city,” said executive director Jodie Medeiros. 
“This tool is working. 
People are lowering their speeds.” 
District 6, represented by Dorsey, currently has seven of the city's 33 cameras, most of them in SoMa. 
The district also records the highest number of crashes involving injuries or fatalities in San Francisco, making it a focal point in the debate over expanding automated enforcement. 
The resolution advanced unanimously from the Board of Supervisors’ Public Safety and Neighborhood Services Committee last week, where Dorsey said the cameras have made streets “feel safer” and argued the early results show “why we should have even more of this life-saving technology.” 
Zieman, whose son’s death prompted traffic-calming improvements and eventually a speed camera near Sherman Elementary, said the issue is urgent. 
“There are probably other Franklin streets out there,” he said. 
“I just hope they don't wait for someone else before they expand the program. 
It’s too late for Andrew.”
