Regional GTFS-RT for the San Francisco Bay Area
511 SF Bay provides GTFS-RT feeds for most participating transit services in the nine-county (Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Solano, and Sonoma) San Francisco Bay Area. Available GTFS-RT feeds can be queried from the Trip Updates and Vehicle Positions data endpoints. In addition to individual GTFS-RT feeds for each transit service provider, 511 SF Bay is currently working on consolidated Regional GTFS-RT feeds that combines GTFS-RT feeds for all transit services of the San Francisco Bay Area.
