The General Transit Feed Specification (GTFS) defines a common format for public transportation schedules and associated geographic information.

The General Transit Feed Specification (GTFS) defines a common format for public transportation schedules and associated geographic information. GTFS "feeds" allow public transit agencies to publish their transit data and developers to write applications that consume that data in an interoperable way. GTFS-realtime is an extension to GTFS that allows public transportation agencies to provide realtime updates about their fleet to application developers.
