Transportation Planning and Studies

The Life of a Plan infographic The goal of the San Francisco County Transportation Authority is to provide a community-minded, proactive voice for transportation planning and management in San Francisco, and create a sustainable vision for the City's future transportation needs. We provide project oversight for many transportation improvements, and lead studies for future projects identified in the San Francisco Transportation Plan. We also work with multiple agencies to coordinate efforts on other transportation enhancements citywide and within the region.

The Transportation Authority develops transportation plans to improve access and safety for everyone. Those plans range from transformational infrastructure projects to smaller, neighborhood-scale efforts. While every plan is unique, download The Life of a Transportation Plan PDF to learn about some of the major elements that go into every plan.

SFTP and Connect SF logosConnectSF is a multi-agency collaborative process to build an effective, equitable and sustainable transportation system for our future.  ConnectSF consists of a coordinated series of planning and policy efforts that identify a long-range vision for San Francisco’s transportation system, the roles specific modes or types of transportation play in that vision, and how we prioritize and fund specific transportation investments in order to set San Francisco on the path to achieve that vision by 2065. Part of the ConnectSF process includes updating the San Francisco Transportation Plan (SFTP), the 30-year blueprint that guides investment in our city’s transportation system.

In July 2017, the Metropolitan Transportation Commission (MTC) and the Association of Bay Area Governments (ABAG) adopted Plan Bay Area 2040 (PBA 2040), a 25-year plan that establishes the nine-county Bay Area region’s vision for transportation with supporting policies and investment strategies.  As the Bay Area's Sustainable Communities Strategy/Regional Transportation Plan (SCS/RTP) it forms a long-range plan that demonstrates how the transportation network and land use development can work together to reduce GHG emissions and create more complete, livable, sustainable communities with sufficient affordable housing, more transportation choices, and easier access to vital services and amenities, such as public transit, shopping, schools, parks, recreation, health care, and more.

PBA 2040 set ambitious transportation and land use goals for the region, including:

  • Reduce per-capita CO2 emissions from cars and light-duty trucks by 15%
  • Increase non-auto mode share by 10%
  • Reduce vehicle operating and maintenance costs due to pavement conditions by 100%
  • Reduce per-rider transit delay due to aged infrastructure by 100%
  • Decrease the share of lower-income residents' household income consumed by transportation and housing by 10%

Inclusion in PBA 2040's list of projects and programs is a prerequisite for receiving state and federal transportation grants, as well as a requirement for expanding projects that may have air quality impacts.  In its role as Congestion Management Agency, the Transportation Authority coordinates San Francisco’s inputs into each 4-year update of the SCS/RTP, and in the last cycle saw many of the submitted projects achieve the status of high performers, including Caltrain Modernization/Downtown Extension, Congestion Pricing on Treasure Island and Downtown, Geary Bus Rapid Transit, and BART Metro.

MTC and ABAG is preceding the next SCS/RTP cycle with an initiative known as Horizon. As part of the initiative, regional planning staff will explore external forces - such as new technologies, unexpected natural or manmade disasters, economic booms and busts, and political volatility - that may fundamentally alter the region’s trajectory over the next few decades. Throughout the process, MTC will engage the public and other stakeholders to figure out how respond to these forces. The Horizon initiative will identify policy responses and investments that perform well under a variety of scenarios. Expected to conclude in summer 2019, Horizon will inform the next SCS/RTP update (Plan Bay Area 2050), which will be adopted in 2021.
