TripUpdate don't show useful info

[wowkin2]

Opened following urls: http://localhost:8080/web/reports/apiCalls/gtfsRealtimeTripUpdatesApiParams.jsp?a=1 http://localhost:8080/api/v1/key/f78a2e9a/agency/1/command/gtfs-rt/tripUpdates?format=human and saw that TripUpdate looks like this:

header {
  gtfs_realtime_version: "1.0"
  incrementality: FULL_DATASET
  timestamp: 1531928043
}

and VehiclePosition contains less information than in source.

Is that expected behavior? I wanted this service to generate TripUpdate from VehiclePosition + GTFS Static

What should I do to get all predictions of how much time to arrival of all vehicles to some stop?

In this file you will need to change the avl module as below.

https://github.com/TheTransitClock/transitclockDocker/blob/MBTA_trial/config/transitclockConfig.xml

from: org.transitclock.custom.mbta.HighFreqAvlModule

to: org.transitime.avl.GtfsRealtimeModule

I had this configured to work with a high frequecy test AVL feed from the MBTA.

[wowkin2]

Changed, restarted (even whole PC to be sure), but still the same:

header {
  gtfs_realtime_version: "1.0"
  incrementality: FULL_DATASET
  timestamp: 1531934342
}

You need to rerun ./go.sh and rebuild the servers again or login to the transitclock-server-instance and change the config file directly in /usr/local/transitclock/config.

Also, in the container you will find a /usr/local/transitclock/logs directory that should provide further info.

@wowkin2 Can this item be closed?

[wowkin2]

Is it ok, or should I do something else? Config is ok, and result is still the same...

[scrudden]

Sorry, my mistake. The module name should have been

org.transitclock.avl.GtfsRealtimeModule

I had given you the old package name.

[wowkin2]

Updated, but no changes. Will write you my URLs on email, so you'll be able to check if it is working on your code. If yes, you'll be able to just make a zip with all files and send them back. If not - will need to find bugs here :yum:

[wowkin2]

Sent. BTW, don't see GTFS_URL anywhere in transitclockConfig.xml file? Should it be there? Maybe that is the reason?

[scrudden]

Can you show me the transitclockConfig.xml that is in the /usr/local/transitclock/config directory of the transitclock-server-instance container?

[scrudden]

I also think that the boundary for the Ukraine will need to be set as per the comment here. It defaults to the US.

https://github.com/TheTransitClock/transitclockDocker/blob/183e07df92545b4a1ddeac1c80c0b8659fab027f/config/transitclockConfig.xml#L34-L47

[wowkin2]

OMG, thanks! Now it works! :smile: Why there is such a restriction? How can I use it?

[wowkin2]

Question, is tripUpdates showing trip_update.stop_time_update.arrival.time from the schedule if schedule_relationship == "SCHEDULED"? Or prediction is based on scheduled and VehiclePositions.

Found trip_update.delay, should I manually calculate trip_update.stop_time_update.arrival.time + trip_update.delay or is it already there?

[scrudden]

Hi,

Can you ask these new questions either on TheTransitClock mailing list or as separate issues in the https://github.com/TheTransitClock/transitime project.

It will make it easier for others to benefit from the information.

Thanks,

Sean.

[wowkin2]

Asked there. Few things that still need to ask here:

• why this information is generated only for first and last route stops?
• why the most of items in TripUpdate have stop_time_update.departure equals 0?

[scrudden]

On the first item, what information do you mean by "this information"? Do you mean the schedule_relationship?
