Welcome to the San Francisco County Transportation Authority

Created in 1989, the Transportation Authority is responsible for long-range transportation planning for the city, and it analyzes, designs and funds improvements for San Francisco's roadway and public transportation networks. The Transportation Authority administers and oversees the delivery of the Prop K half-cent local transportation sales tax program. It also serves as the designated Congestion Management Agency (CMA) for San Francisco under state law, and acts as the San Francisco Program Manager for grants from the Transportation Fund for Clean Air (TFCA). The Transportation Authority was designated Treasure Island Mobility Management Agency (TIMMA) in 2014, charged with planning for sustainable mobility on Treasure Island, coordinating new ferry and regional bus service, on-island shuttle, bike share, and car share opportunities.

Transportation Authority Releases “TNCs Today” Report, Highlighting Uber, Lyft Activity in San Francisco

Rider enters a TNC vehicleThe San Francisco County Transportation Authority has released “TNCs Today: A Profile of San Francisco Transportation Network Company Activity.” The draft report is the first comprehensive estimate of the volume, frequency and coverage of ride-hailing trips by Uber and Lyft in San Francisco.

Key findings of the report, which focused only on Transportation Network Company trips made entirely within San Francisco, include:

  • On a typical weekday, TNCs make more than 170,000 vehicle trips within San Francisco, approximately 12 times the number of taxi trips, representing 15% of all intra-San Francisco vehicle trips.
  • TNC trips are concentrated in the densest and most congested parts of San Francisco, including the downtown and northeastern core of the city. At peak periods, TNCs are estimated to comprise 20-26% of vehicle trips in Downtown areas and the South of Market. At the other end of the range, TNCs comprise 2%-4% of peak vehicle trips in the southern and western part of the city.
  • On an average weekday, more than 5,700 TNC vehicles operate on San Francisco streets during the peak period. On Fridays, over 6,500 TNC vehicles are on the street at the peak.
  • TNCs drive approximately 570,000 vehicle miles within San Francisco on a typical weekday. This accounts for 20% of all local daily vehicle miles traveled (VMT) and includes both in-service and out-of-service mileage. Taken over total weekday VMT, which includes regional trips, local TNC trips account for an estimated 6.5% of total weekday vehicle miles traveled.
  • TNCs provide broader geographic coverage than taxis, though there appear to be lower levels of both types of trips in the south and southeast part of the city.

I-80 YBI East-side rampsThe San Francisco County Transportation Authority’s Yerba Buena Island I-80 Westbound Ramps project won two major project delivery awards.

The $100 million project was opened to traffic last fall and is the agency’s first major capital construction project.

Project partners included Caltrans, Bay Area Toll Authority (BATA), Treasure Island Development Authority (TIDA), and the U.S. Coast Guard. The project’s 13.2 percent participation by Disadvantaged Business Enterprises included more than two dozen  women-, African-American- and LGBT-owned firms.

The Construction Management Association of America (Northern California Chapter) on May 18 awarded the Transportation Authority and its partners its large project Achievement Award for projects exceeding $50 million in value. Separately, the California Transportation Foundation on May 24 named the YBI Ramps the Interchange Project of the Year.

T2045 logoThe Transportation 2045 (T2045) Task Force has been convened by the Honorable Mayor Edwin M. Lee and Board of Supervisors President London Breed. The Task Force will be co-chaired by the Mayor's Chief of Staff, Steve Kawa, and San Francisco County Transportation Authority Chair and City Supervisor, Aaron Peskin. Task Force members represent the community at large, including individuals representing neighborhoods; small and large businesses; transportation, housing and environmental justice advocacy groups; labor and civic organizations; and city and regional transportation agencies.

To ensure a safe, reliable, and affordable transportation system, the Task Force will meet over the coming months to discuss options for how the City can generate revenue, prioritize expenditures over the long-term, and balance regional and neighborhood-level needs.

The goals of the Task Force are to:

  • Identify transportation funding needs and gaps in resources
  • Identify potential revenue options to close the gaps

T2045 will build off the City's previous transportation planning efforts (including the Transportation Task Force 2030 process, The San Francisco Transportation Plan, Plan Bay Area, and Propositions J and K previously on the November 2016 ballot) and incorporate the progress we've made in the intervening years as well as the new challenges we face as a city.

SFCTA opens Yerba Buena Island’s Vista Point to Cyclists, Pedestrians

Ribbon-cutting to open the YBI Vista Point The San Francisco County Transportation Authority, in cooperation with the Bay Area Toll Authority, Caltrans and Treasure Island Development Authority, opened the Vista Point visitor area on Yerba Buena Island on May 2.

Situated at the San Francisco (western) terminus of the San Francisco-Oakland Bay Bridge bicycle-pedestrian path, Vista Point is designed as a relaxation and rejuvenation area for visitors to Yerba Buena Island. Featuring restrooms, benches, a hydration station and bike racks, Vista Point offers sweeping views of the east span of the Bay Bridge and Oakland.

A shuttle equipped to transport up to eight bicycles operates 15- to 20-minute service between Vista Point and Treasure Island on Saturdays and Sundays.

The opening of Vista Point comes as Caltrans extends the hours of the Bay Bridge’s bike-pedestrian path to weekdays as well as weekends. Vista Point will be open the same hours as the Bay Bridge bike-pedestrian path: Monday-Friday, 6:00 AM–8:00 PM; Saturday and Sunday, 6:00 AM–8:00 PM.

The Neighborhood Transportation Improvement Program (NTIP) funds community-based neighborhood-scale planning efforts, especially in underserved neighborhoods and areas with vulnerable populations (e.g. seniors, children, and/or people with disabilities).

The NTIP was developed in response to mobility and equity analysis findings from the San Francisco Transportation Plan (SFTP), the city’s 30-year blueprint guiding transportation investment in San Francisco, and the Transportation Authority Board's desire for more focus on neighborhoods, especially on Communities of Concern and other underserved neighborhoods.

The SFTP found that walking, biking and transit reliability initiatives are important ways to address socio-economic and geographic inequities.

The NTIP is made possible by the Transportation Authority through grants from San Francisco's half-cent sales tax for transportation.

MyStreetSF Projects Map logoMyStreetSF Projects Map thumbnailFrom signals to streetcars, bicycles to boulevards, from pedestrian safety to paving, the Transportation Authority provides funding for hundreds of transportation projects citywide. The MyStreetSF interactive map shows projects currently underway, proposed, and recently completed that are funded by, or prioritized for funding by the Transportation Authority, as well as those for which the we provide some level of oversight, in our role as Congestion Management Agency for San Francisco. The MyStreetSF interactive map allows you to search for projects by location, Supervisorial District, project type (e.g., bicycle, pedestrian safety, transit rehabilitation), project sponsor, or timeline. Click on a project on the map to see key information (e.g., short description, schedule, cost) and a link to the project page and/or project sponsor’s main page. The map page also includes information on city-wide projects and programs like Bicycle Education and Outreach. READ MORE

Citizens (or Community) Advisory Committees, also known as CACs, are an important part of our planning efforts: they give the public—community and business stakeholders—a voice in the direction and scope of many of our projects, analyze benefits and impacts on San Francisco’s many communities, and recommend courses of action.

We currently have one vacancy on our agency-wide CAC. If you’re interested, get in touch with us! Call 415.522.4800 or send us an email. We need your guidance and support!
