Introduction

The Transportation Authority is the Congestion Management Agency for San Francisco. As required by state law, we develop and adopt a Congestion Management Program to monitor activity on our transportation network and adopt plans for mitigating traffic congestion in the city. Our Congestion Management work also aids in the development of the San Francisco Transportation Plan and provides input to San Francisco’s priorities for Plan Bay Area every four years.

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 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 promote safety, better manage congestion, improve air quality, and facilitate sustainable development.

2021 Congestion Management Program

The 2021 CMP update shows recent travel trends have been disrupted due to the profound effect the pandemic had on peoples’ health, livelihoods, activities and the economy. Roadway and transit speeds improved for the first time in a decade. However, as the city recovers congestion has been returning to streets and freeways, in some cases to nearly pre-pandemic levels.
