GTFS data

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 data

As GTFS provides static information about the transit data, GTFS-Realtime as the name suggests provides Realtime information regarding the transit data which includes the trips that are currently active, the current vehicle position on the trip, the stops already covered by the vehicle along the trip etc.

GTFS-Realtime feed follows Google’s GTSF-Realtime feed specifications. The documentation can be found at

The feed has two entities:

Trip Updates: Contains Realtime predicted arrival/departure time for stops along the route. The file is available in two formats: Protocol buffer and Text format. Protocol buffer file can be found at and the Text file can be found at

Trip Updates files is updated every 60 seconds.

For more information on trip updates, please visit

Vehicle Positions: Contains Realtime vehicle positioning information along the route.

Similar to Trip Updates, vehicle positions file is also available in Protocol Buffer and Text format which can be found here and respectively.
