SamTrans. The San Mateo County Transit District, commonly known by its brand name, is the primary public transportation agency for San Mateo County, California. It operates an extensive network of fixed-route bus services, paratransit, and community shuttles across the county and into adjacent regions. The agency also provides funding and oversight for Caltrain commuter rail services and participates in the Metropolitan Transportation Commission.

History

The district was formed in 1976 following the passage of the San Mateo County Transit District Act by the California State Legislature, consolidating several private and municipal bus operators. Key early milestones included assuming operations from the Peninsula Transit District and integrating services with the former Southern Pacific Transportation Company's Peninsula Commute line, which later evolved into Caltrain. Throughout the 1980s and 1990s, it expanded service coordination with neighboring agencies like the San Francisco Municipal Transportation Agency and the Santa Clara Valley Transportation Authority. The early 2000s saw the implementation of the Ecolane software for its Redi-Wheels and RediCoast paratransit services, and more recent decades have focused on introducing zero-emission buses and modernizing fare systems in partnership with the Clipper card program.

Services

It operates over 70 fixed-route lines, including local, express, and school tripper services, connecting communities from Daly City to Palo Alto and extending into parts of San Francisco and Fremont. Key corridors include the El Camino Real and routes serving major employment centers like San Francisco International Airport and the Facebook campus in Menlo Park. The agency also manages the Redi-Wheels and RediCoast programs for ADA-compliant paratransit, and funds the Community Shuttle program for local circulators in cities such as Redwood City and San Bruno. It provides significant operating support for the Caltrain commuter rail system and participates in regional fare integration through the Bay Area's 511 and the Clipper card.

Fleet

The fleet consists primarily of heavy-duty transit buses, including models from New Flyer, Gillig, and North American Bus Industries. A major initiative is the transition to a zero-emission fleet, with battery-electric buses from Proterra and BYD already in service, supported by charging infrastructure at divisions in South San Francisco and San Carlos. The paratransit service utilizes accessible cutaway vans and minibuses, while the Community Shuttle program operates smaller vehicles. All fixed-route buses are equipped with automatic vehicle location systems, bicycle racks, and are compliant with the Americans with Disabilities Act of 1990.

Governance and funding

The agency is governed by a nine-member Board of Directors appointed by the San Mateo County Board of Supervisors and city councils within the county. Day-to-day operations are managed by a general manager and executive team. Primary funding sources include local sales tax measures like Proposition A and Measure A, federal grants from the Federal Transit Administration, state allocations from the California State Transportation Agency, and farebox revenue. It also receives funding through the Metropolitan Transportation Commission for regional operations and capital projects.

Facilities

Its primary administrative headquarters and central maintenance division are located in San Carlos, California. Other major operating divisions and maintenance facilities are situated in South San Francisco and Redwood City. The agency utilizes transit centers and hubs throughout the county, including the Daly City BART Station, the Redwood City Transit Center, and the Hillsdale Shopping Center, for passenger connections. It also maintains park-and-ride lots in communities like Pacifica and San Bruno, and is developing new charging depots for its electric bus fleet.

Ridership

Pre-pandemic annual ridership regularly exceeded 10 million passenger trips on fixed-route services, with additional demand for its Redi-Wheels paratransit. Ridership patterns are heavily influenced by commute flows to major employment centers like San Francisco, Silicon Valley, and San Francisco International Airport. The agency participates in regional surveys like the Census Transportation Planning Products and collaborates with Caltrain and the Bay Area Rapid Transit on integrated passenger studies. Recent efforts to recover from the COVID-19 pandemic impacts include service realignments and promotional fare programs.
