Core Capacity Transit Study

The Bay Area Core Capacity Transit Study (CCTS) is a collaborative effort to find and prioritize investments that will improve travel on public transportation to and from the San Francisco Core.

Update

The Core Capacity Transit Study will soon release a public draft of the study’s final report. Please check back to this page for the latest updates.

Thank you to those who attended our two workshops, on February 1 and 7 at SPUR’s San Francisco and Oakland locations. Please see the “Meeting Materials” section below to find the presentation and the project package summaries discussed during the workshops.

What is the study about?

The study is a joint effort of five transit operators: BART, Muni, AC Transit, Caltrain, and the Water Emergency Transportation Authority, in coordination with the San Francisco County Transportation Authority (SFCTA) and the Metropolitan Transportation Commission (MTC).

Every day, transit operators move hundreds of thousands of people into and out of San Francisco’s Core, which includes portions of the Financial District, South of Market (SoMa), Mid-Market and Mission Bay neighborhoods. Facing increasingly crowded conditions as the region and transit ridership continues to grow, our transit system is challenged to deliver quality service to riders both now and in the future.

The five transit operators are all committed to identifying investments and improvements to increase transit capacity to the San Francisco Core.  All of these operators are independently considering various improvements and investments to their respective systems (see the full list of prerequisite projects), and this study is the first to date to bring the major transit operators together to address this regional issue in a comprehensive, coordinated manner.

The study’s findings and recommendations will support sustainable economic growth and improve the quality of life for the region’s residents, visitors and workforce.

Study Area and Networks of Focus

The CCTS Study Area includes two primary transit corridors: the Transbay Corridor and the San Francisco Metro Corridor.

The Transbay Corridor focuses on investments to transport commuters on BART, AC Transit and WETA from the East Bay, and it explores potential new connections across the Bay. The San Francisco Metro Corridor focuses on Muni’s light rail and bus network, Caltrain’s peninsula service to San Francisco, and BART service through the southern neighborhoods of San Francisco.

Planning Horizons

The study is looking at short-, medium-, and long-term investments that could help steadily upgrade the overall transportation system and keep pace with anticipated population growth for the next quarter century.  As an important step toward funding and implementation, the projects developed and prioritized through the Core Capacity Transit Study will be incorporated into the full list of priorities for the nine-county region in Plan Bay Area 2040, the region’s long-term transportation and land-use plan.

Over the course of the study, the Core Capacity team will share presentations and draft documents. Find documents posted to date below.

Summary Materials:

Transbay:

  • Transbay Problem Statement: A synthesis of the trends and challenges that the study aims to address in the transbay corridor
  • Transbay Capacity and Demand Summary: A detailed review of ridership trends and a description of methodologies used to forecast future demand in the corridor and categorize planned capacity-increasing projects (“prerequisites”)
  • Initial Engineering Study Memo  and Appendix: Initial review of potential transbay crossing landing locations and review of potential tunneling techniques and technologies

San Francisco Metro:

Market Assessments:

The CCTS was established through commitments by seven Bay Area agencies and is also supported by a U.S. Department of Transportation TIGER grant. The seven partner agencies are:

  • Lead agency: Metropolitan Transportation Commission (MTC)
  • Transit operators: San Francisco Municipal Transportation Agency (SFMTA), Bay Area Rapid Transit (BART), Alameda-Contra Costa Transit (AC Transit), the Water Emergency Transportation Authority (WETA), and Caltrain
  • Funding and planning partner: San Francisco County Transportation Authority (SFCTA)
