GTFS Realtime Changes

The GTFS Realtime Specification is not set in stone. Instead, it is an open specification developed and maintained by the community of transit agencies, developers, and other stakeholders who use GTFS Realtime. It is expected that this community of producers and consumers of GTFS Realtime data will have proposals for extending the spec to enable new capabilities. To help manage that process, the following procedures and guidelines have been established.

The official specification, reference and documentation are written in English. If a translation to a different language differs from the English original, the latter takes precedence. All communication is performed in English.
