No Method of mapping vehicle to trip_id

[jonathonwpowell]

Currently there is no method of mapping a vehicle to a trip_id, as trip_id is not provided in the Transloc API.

Here are my ideas to create a generic way to create this mapping:

• Add an optional parameter that points to a URL that will do the mapping
  • This endpoint will expect an array of vehicles, positions, timestamps, & routes
  • The endpoint will return the trip_id for each vehicle, or no trip_id if the endpoint knows the vehicle is not on a trip
  • While the endpoint could work in many ways, I imagine that it will try and match the vehicle to a trip_id, and then cache the result for a length of time or until values changed.
  • This method of having a separate endpoint do the mapping allows this project to remain stateless, as well as allow for other data that may be agency specific to be added in
• Before mapping to the gtfs-rt format, if the url is passed in it will call it. It will then add the trip_id to all of the vehicles, or remove them if they have no trip_id
