Light rail not working, train transit acting weird #109

Open marsxul opened 8 years ago

marsxul commented 8 years ago

Trips that should have an easy light rail trip are showing as such, 4+ miles of walking. Something is wrong with the intermodal connectivity.

Light rail shows up with this api call (Hostetter to River Oaks) but trip times don't seem to make much sense.

I see some OTP errors. Perhaps there is an issue with VTA GTFS feed related to light rail.

I talked with Everley about this to see if she could spot anything amiss about this (she's the resident GTFS expert). She said she'd take a deeper look, but her initial impression was that these times (if the 1:03_21 portion of VTA:902:1:03_21_D is the time) is too close together to be present in the GTFS as stop information.

Would you be able to provide a little more information about this error and what this time and weight being "incremented by a negative amount" means?

Fixed with the move to OTP v20.
