Users can now download GTFS-RT Trip Updates, Vehicle Positions, and Alerts for all of San Francisco Bay Area’s real-time enabled transit agencies in single consolidated feeds using agency code ‘RG’.

In the Works

511 SF Bay provides consolidated Regional GTFS-RT feeds for all real-time enabled transit services in the nine-county San Francisco Bay Area. In addition, we are currently working on a real-time data archive that will allow data consumers to download actual arrival times in a monthly historic data feed. This data, alongside the historic scheduled arrivals/departures can be valuable for transit service analysis, transportation planning, and other research purposes.


Release timeline:

Regional real-time data archive is expected to be available in Fall 2021 or Winter 2022.
