predictions not available for all stops en-route of a longer trip

[wkulesza]

Expected functionality When a trip is assigned and prediction is available - predictions should be available for all stops en-route of that trip

Describe the bug At a given time, trip has predictions up to a given stop and following stops have no predictions. As the bus is travelling, this seems to update itself gradually.

To Reproduce Use a GTFS with trips that are long - like 2 hours, run a standard setting TC docker with autoassigner on and either gtfs-rt vehicle positions or traccar-avl source.

Screenshots Predictions available for one stop:

Predictions for next stop are not available:

Predictions for that next stop become available after some time:

Version: Newest TC docker.

Configuration: Standard

Additional context Add any other context about the problem here.

You can set how far forward into the future you wish to generate predictions.

I tried adding this to import_gtfs.sh:

java -Xmx4g -Dtransitclock.core.agencyId=$AGENCYID -Dtransitclock.configFiles=/usr/local/transitclock/config/transitclock.properties -Dtransitclock.logging.dir=/usr/local/transitclock/logs/ -Dlogback.configurationFile=$TRANSITCLOCK_CORE/transitclock/src/main/resouces/logbackGtfs.xml -cp /usr/local/transitclock/Core.jar org.transitclock.applications.GtfsFileProcessor -gtfsUrl $GTFS_URL  -maxTravelTimeSegmentLength 100  -maxPredictionsTimeSecs 7200

but got:

Unrecognized option: -maxPredictionsTimeSecs

[scrudden]

This property is used by core rather than by the GTFS file processor. I would normally add this to the property file like

transitclock.core.maxPredictionsTimeSecs=7200

[wkulesza]

ok it helps - actually it reads already: transitclock.core.maxPredictionTimeForDbSecs=1200 transitclock.core.maxPredictionsTimeSecs=1800

so i changed 1800 to 7200 and finally can see predictions to 60 minutes.

@wkulesza Can this be closed?

[wkulesza]
