A Metropolitan Planning Organization (MPO) is a federally mandated and federally funded transportation policy-making organization in the United States that is made up of representatives from local government and governmental transportation authorities. They were created to ensure regional cooperation in transportation planning. MPOs were introduced by the Federal-Aid Highway Act of 1962, which required the formation of an MPO for any urbanized area (UZA) with a population greater than 50,000. Federal funding for transportation projects and programs are channeled through this planning process. Congress created MPOs in order to ensure that existing and future expenditures of governmental funds for transportation projects and programs are based on a continuing, cooperative, and comprehensive ("3-C") planning process. Statewide and metropolitan transportation planning processes are governed by federal law. Transparency through public access to participation in the planning process and electronic publication of plans now is required by federal law. As of 2015, there are 408 MPOs in the United States.
The Clipper card is a reloadable contactless smart card used for automated fare collection in the San Francisco Bay Area. First introduced as TransLink in 2002 by the Metropolitan Transportation Commission (MTC) as a pilot program, it was rebranded in its current form on June 16, 2010. Like other transit smart cards such as the Oyster card, the Clipper card is a credit card-sized stored-value card capable of holding both cash value and transit passes for the participating transit agencies. In addition to the traditional plastic card, Clipper is available as a virtual card in Google Wallet and Apple Wallet. Clipper is accepted by nearly all public transit services in the Bay Area, including but not limited to Muni, BART, Caltrain, AC Transit, SamTrans, Golden Gate Transit, Golden Gate Ferry, San Francisco Bay Ferry, and VTA.
The Metropolitan Transportation Commission (MTC) is the government agency responsible for regional transportation planning and financing in the San Francisco Bay Area. It was created in 1970 by the State of California, with support from the Bay Area Council, to coordinate transportation services in the Bay Area's nine counties: Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma. The MTC is fourth most populous metropolitan planning organization in the United States.
Sonoma–Marin Area Rail Transit (SMART) is a rail line and bicycle-pedestrian pathway project in Sonoma and Marin counties of the U.S. state of California. When completed, the entire system will serve a 70-mile (110 km) corridor between Cloverdale in northern Sonoma County and Larkspur Landing in Marin County. In 2023, the system had a ridership of 749,700, or about 2,600 per weekday as of the first quarter of 2024.
El Cerrito del Norte station is a Bay Area Rapid Transit (BART) station located on Cutting Boulevard in El Cerrito, California. The station is served by the Orange and Red lines. Located near San Pablo Avenue and Interstate 80, it serves as a regional transit hub for local AC Transit bus services, and for commuter feeder services from Solano, Napa, and Marin Counties in the North Bay plus western Contra Costa County. Opened in 1973, the station was renovated in 2017–2021 to add additional elevators, stairs, and lobby space.
The San Francisco Bay Trail is a bicycle and pedestrian trail that when finished will allow continuous travel around the shoreline of San Francisco Bay. As of 2020, 356 miles (573 km) of the trail have been completed. When finished, the trail will be over 500 miles (800 km) of paved and gravel paths, bike lanes, and sidewalks, linking 47 cities across nine counties and crossing seven toll bridges. It is a project of the Association of Bay Area Governments (ABAG) and the Metropolitan Transportation Commission (MTC), in collaboration with other agencies, private companies, non-profit organizations, and advocacy groups.
The Golden Gate Bridge, Highway and Transportation District is a special-purpose district that owns and operates three regional transportation assets in the San Francisco Bay Area: the iconic Golden Gate Bridge, the Golden Gate Ferry system and the Golden Gate Transit system. All three assets connect Marin County with San Francisco. In the 1950s and 60s, officials in charge of the Golden Gate Bridge District coordinated to kill the popular BART extension into Marin County in order to preserve their own toll revenues.
People in the San Francisco Bay Area rely on a complex multimodal transportation infrastructure consisting of roads, bridges, highways, rail, tunnels, airports, seaports, and bike and pedestrian paths. The development, maintenance, and operation of these different modes of transportation are overseen by various agencies, including the California Department of Transportation (Caltrans), the Association of Bay Area Governments, San Francisco Municipal Transportation Agency, and the Metropolitan Transportation Commission. These and other organizations collectively manage several interstate highways and state routes, eight passenger rail networks, eight trans-bay bridges, transbay ferry service, local and transbay bus service, three international airports, and an extensive network of roads, tunnels, and bike paths.
The All Nighter is a night bus service network in the San Francisco Bay Area, California. Portions of the service shadow the rapid transit and commuter rail services of BART and Caltrain, which are the major rail services between San Francisco, the East Bay, the Peninsula, and San Jose. Neither BART nor Caltrain operate owl service due to overnight track maintenance; the All Nighter network helps fill in this service gap. The slogan is, "Now transit stays up as late as you do!"
The government of the City and County of San Francisco utilizes the "strong mayor" form of mayoral/council government, composed of the Mayor, Board of Supervisors, several elected officers, and numerous other entities.

Bike East Bay, formerly known as East Bay Bicycle Coalition, is a Californian non-profit organization that worked since 1972 toward "promoting bicycling as an everyday means of transportation and recreation" in Alameda and Contra Costa counties of the California's East Bay.
Cycling in San Francisco has grown in popularity in recent years, aided by improving cycling infrastructure and community support. San Francisco's compact urban form and mild climate enable cyclists to reach work, shopping, and recreational destinations quickly and comfortably. Though San Francisco's famed steep hills can make cycling difficult, many parts of the city are relatively flat, including some of the most densely populated. However, heavy automobile traffic, the lack of bike lanes on many streets, and difficulty in crossing major streets deter most residents from cycling frequently in San Francisco.
The National Association of City Transportation Officials (NACTO) is a coalition of the Departments of Transportation in North American cities.
The government of California has an extensive system of local government that manages public functions throughout the state. Like most states, California is divided into counties, of which there are 58 covering the entire state. Most urbanized areas are incorporated as cities, though not all of California is within the boundaries of a city. School districts, which are independent of cities and counties, handle public education. Many other functions, especially in unincorporated areas, are handled by special districts, which include municipal utility districts, transit districts, health care districts, vector control districts, and geologic hazard abatement districts.
San Jose, California has various cycling routes on roads and trails used by both commuters and recreational riders. The city has plans to expand the current 285 miles (459 km) of bike lanes to 400 miles (640 km), and the current 60 miles (97 km) of trails to 100 miles (160 km). San Jose was ranked as a bronze-level bicycle-friendly community by the League of American Bicyclists.
