Inconsistency documentation https://developers.google.com/transit/gtfs-realtime/guides/vehicle-positions#vehiclestopstatus

[sven4all]

The documentation in https://developers.google.com/transit/gtfs-realtime/guides/vehicle-positions#vehiclestopstatus is not consistent with the documentation in the .proto files https://developers.google.com/transit/gtfs-realtime/gtfs-realtime-proto and gtfs.org

On https://developers.google.com/transit/gtfs-realtime/guides/vehicle-positions#vehiclestopstatus IN_TRANSIT_TO is described as "the referenced stop is the next stop for the vehicle - default" while in the .proto file it's described the following:

enum VehicleStopStatus {
    // The vehicle is just about to arrive at the stop (on a stop
    // display, the vehicle symbol typically flashes).
    INCOMING_AT = 0;

    // The vehicle is standing at the stop.
    STOPPED_AT = 1;

    // The vehicle has departed and is in transit to the next stop.
    IN_TRANSIT_TO = 2;
  }
  // The exact status of the vehicle with respect to the current stop.
  // Ignored if current_stop_sequence is missing.
  optional VehicleStopStatus current_status = 4 [default = IN_TRANSIT_TO];

current_stop_sequence is described:

// The stop sequence index of the current stop. The meaning of
  // current_stop_sequence (i.e., the stop that it refers to) is determined by
  // current_status.
  // If current_status is missing IN_TRANSIT_TO is assumed.
  optional uint32 current_stop_sequence = 3;

What is the correct way to interpreted it? Should the current_stop_sequence be updated directly after the bus is departed from the previous stop (what https://developers.google.com/transit/gtfs-realtime/guides/vehicle-positions#vehiclestopstatus IN_TRANSIT_TO suggests) or should it be updated when the vehicle arrives at the next stop what the .proto file and gtfs.org are suggesting.

@sven4all Thanks for raising this issue! https://github.com/google/transit is the best place to have this discussion so I would suggest opening this issue there. To my knowledge this repo is mostly unmonitored.
