San Francisco Municipal Transportation Agency

Muni provides public transportation services within San Francisco, operating bus routes, light rail lines, historic streetcar lines, and the iconic cable car system. It serves residents, commuters, and visitors by connecting neighborhoods, employment centers, and tourist destinations across the city. The agency is responsible for scheduling, vehicle maintenance, fare collection, and customer information for these modes. As a municipal transit provider, Muni integrates its services with other regional transit operators to facilitate seamless travel. Its core mission is to deliver safe, reliable, and accessible transportation to the public. The organization also manages associated infrastructure such as stations, stops, and maintenance facilities.

Muni is a department of the City and County of San Francisco and operates under the oversight of the San Francisco Municipal Transportation Agency (SFMTA). It is publicly owned and funded through a combination of fare revenue, local taxes, and state and federal grants. The agency’s distinguishing attributes include its role as the primary transit provider for a major urban center and its operation of the historic cable car system, a National Historic Landmark. In November 2016, Muni experienced a ransomware attack that encrypted internal systems and disrupted fare collection, allowing free rides until systems were restored without paying the ransom. This incident underscored the importance of cybersecurity resilience for public transit agencies. Muni’s structural status as a city agency ensures accountability to local government and the public it serves.
