I’m noticing that some of the coordinates returned by the GTFS-R vehicle position endpoint is a little strange.
I’ve been tracking a particular vehicle yesterday:
Vehicle ID: 4337.4338.4339.4340.4341.4342.4343.4344
Trip ID: 152T.435.123.60-20160801.A.8.42505972
Route ID: WL_1b
In sequential order, the GTFS-R feed returned the vehicle position to be:
Granville.Pendle Hill 3 Loc @ 1470063822
Granville.S18.1 Loc @ 1470063915
Granville.Toongabbie 3 Loc @ 1470063955
However, the coordinates returned for
Granville.S18.1 Loc deviated significantly from the expected route:
Would this be because
Granville.S18.1 Loc was incorrectly returned by the feed? or perhaps the coordinates for
Granville.S18.1 Loc are placed on the wrong part of the track
Pink is the route as per shapes.txt, blue is the route as plotted by the data returned by the GTFS-R feed. Star points are the individual nodes being plotted by the data returned by the GTFS-R feed.
