SAN FRANCISCO CONGESTION MANAGEMENT PROGRAM

The Transportation Authority is the designated Congestion Management Agency for San Francisco. We are required by state law to develop and adopt a Congestion Management Program to monitor activity on our transportation network and adopt plans for mitigating traffic congestion in the city.

Every two years, we release a report to update San Francisco’s Congestion Management Program. This report analyzes the performance of our transportation network, including transit, cars, bicycles, and pedestrians. The The performance measures are primarily based on INRIX roadway speed data and SFMTA vehicle telemetry data, augmented by other sources. The report also identifies ways to increase the productivity of existing transportation infrastructure and encourage more efficient use of transportation investments in order to better manage congestion, improve air quality, and facilitate sustainable development.

2017 CONGESTION MANAGEMENT PROGRAM

Our latest congestion monitoring data reveals that auto speeds have continued worsen since 2015. In contrast, transit speeds and transit reliability have remained steady, meaning that transit is more competitive with autos than in past years, an outcome consistent with San Francisco’s “transit-first” policies. Read "Behind the Numbers" to learn more.
