Project Summary

Assembly Bill 645, passed in 2023, authorized a speed safety camera pilot program in six cities to reduce speeding and improve traffic safety, particularly in high-crash areas. This project evaluates the safety impacts of speed camera installation in San Francisco—the first city to implement a pilot—using telematics data, traffic volume and speed pattern data, and citation information. It will assess changes in speeding behavior before and after camera installation and analyze the geographic distribution of citations to understand equity implications across neighborhoods.

Abstract

Public transit systems in California sit at a financial crossroads. Ridership has recovered slowly and unevenly since the pandemic, with commuter-focused transit services to and from downtowns continuing to struggle the most. While other sources of transit funding such as sales taxes have recovered, fare revenues have not. As one-time federal relief funding is spent down, some transit agencies in California and across the U.S. sit at the edge of a fiscal cliff. To better understand the scale of this challenge and how agencies are responding, researchers at the UC Institute of Transportation Studies analyzed financial data from transit agencies, examined federal databases, and conducted surveys and interviews with agency staff. This work provides a clearer picture of current conditions and the strategies agencies are considering to stabilize their budgets.
