GTFS or the General Transit Feed Specification defines a common data format for public transportation schedules and associated geographic information. [1] GTFS contains only static or scheduled information about public transport services, and is sometimes known as GTFS Static or GTFS Schedule to distinguish it from the GTFS Realtime extension, which defines how information on the realtime ...
GTFS Realtime (also known as GTFS-rt) is an extension to GTFS, in which public transport agencies share real-time vehicle locations, arrival time predictions, and alerts such as detours and cancellations via Protocol Buffers web server. [1] Realtime location data is created continuously by an agency from automatic vehicle location (AVL) systems ...

The Framework provides a uniform architecture for defining data messages either as request/response pairs or as publish/subscribe services. The payload content model is separated from the messaging aspects so that the same payload content can be used in both request and subscription services and the same common messaging components can be used ...
For transit route planners to work, transit schedule data must always be kept up to date. To facilitate data exchange and interoperability between different trip planners, several standard data formats have emerged. The General Transit Feed Specification, developed in 2006, [22] is now used by hundreds of transit agencies around the world.
