Class GTFSRealtimeStopTimeProperties

Supports real-time stop assignments. Refers to a stop_id defined in the GTFS stops.txt. The new assigned_stop_id should not result in a significantly different trip experience for the end user than the stop_id defined in GTFS stop_times.txt. In other words, the end user should not view this new stop_id as an "unusual change" if the new stop was presented within an app without any additional context. For example, this field is intended to be used for platform assignments by using a stop_id that belongs to the same station as the stop originally defined in GTFS stop_times.txt. To assign a stop without providing any real-time arrival or departure predictions, populate this field and set StopTimeUpdate.schedule_relationship = NO_DATA. If this field is populated, it is preferred to omit StopTimeUpdate.stop_id and use only StopTimeUpdate.stop_sequence. If StopTimeProperties.assigned_stop_id and StopTimeUpdate.stop_id are populated, StopTimeUpdate.stop_id must match assigned_stop_id. Platform assignments should be reflected in other GTFS-realtime fields as well (e.g., VehiclePosition.stop_id). NOTE: This field is still experimental, and subject to change. It may be formally adopted in the future.
