Class GtfsRtTripFeed

java.lang.Object

org.transitime.api.gtfsRealtime.GtfsRtTripFeed

public class GtfsRtTripFeed
extends java.lang.Object

For creating GTFS-realtime trip feed. The data is obtained from the server via RMI.

Note: for the trip feed predictions that are schedule based instead of GPS based the StopTimeEvent uncertainty is set to SCHED_BASED_PRED_UNCERTAINTY_VALUE so that the client can treat the prediction differently. If a vehicle is delayed and not moving then uncertainty is set to DELAYED_UNCERTAINTY_VALUE. And if a vehicle is late and the prediction is for a subsequent trip then uncertainty is set to LATE_AND_SUBSEQUENT_TRIP_UNCERTAINTY_VALUE.
