Transit Data

511 SF Bay’s Portal for Open Transit Data. Data is free and available using a token.

511 SF Bay provides transit data in both bulk and API quantities for all publicly available transit service providers in the San Francisco Bay Area. Besides GTFS and GTFS-Realtime (Trip Updates, Vehicle Positions, Service ALerts) feeds in bulk, a number of APIs modeled after SIRI and NeTEx standards are also available. Available transit data feeds include:

  1. Static transit data in General Transit Feed Specification (GTFS) and Open 511 SIRI/NeTEx API formats
  2. Real-time transit data via Open 511 SIRI APIs and GTFS-Realtime

Once you have obtained your API token, you can choose any combination of data endpoints from the following list to obtain the data you need. The default rate limit per API token is 60 requests per 3600 seconds. If you need increased rate limit for your purpose, please send your request to 511sfbaydeveloperresources@googlegroups.com. For more detail on these data endpoints, you can download the technical specification.
