GTFS-realtime provides live alert, vehicle location, and arrival-prediction data in an industry-standard format. GTFS-realtime is best for retrieving data for the whole system at once in a relatively small package, but must be extrapolated using the agency's GTFS data to be meaningful. See Google's GTFS-realtime documentation for more information on the GTFS-realtime format.
You can view updated specification extension, archive, and licensing documentation for the MBTA's implementation of GTFS Realtime on our MBTA GTFS documentation page.
Please note this is intended to supplement, not replace, documentation on GTFS Realtime itself.
