start_and_end_range_equal ERROR 1

start_and_end_range_equal

Two date or time fields are equal.

The fields frequencies.start_date and frequencies.end_date have been found equal in frequencies.txt. The GTFS spec is currently unclear how this case should be handled (e.g., is it a trip that circulates once?). It is recommended to use a trip not defined via frequencies.txt for this case.

You can see more about this notice here.

filename (?) The name of the faulty file. csvRowNumber (?) The row number of the faulty record. startFieldName (?) The start value's field name. endFieldName (?) The end value's field name. value (?) The faulty value.

stop_time_with_arrival_before_previous_departure_time

Backwards time travel between stops in stop_times.txt

For a given trip_id, the arrival_time of (n+1)-th stoptime in sequence must not precede the departure_time of n-th stoptime in sequence in stop_times.txt.

You can see more about this notice here.

csvRowNumber (?) The row number of the faulty record. prevCsvRowNumber (?) The row of the previous stop time. tripId (?) The trip_id associated to the faulty record. arrivalTime (?) Arrival time at the faulty record. departureTime (?) Departure time at the previous stop time.

fast_travel_between_consecutive_stops

A transit vehicle moves too fast between two consecutive stops.

The speed threshold depends on route type:

1 Subway 150
2 Rail 500
3 Bus 150
4 Ferry 80
5 Cable tram 30

fast_travel_between_far_stops WARNING 35

fast_travel_between_far_stops

A transit vehicle moves too fast between two far stops.

Two stops are considered "far" if they are more than 10 km apart. This normally indicates a more serious problem than too fast travel between consecutive stops.

The speed threshold depends on route type and are the same as fast_travel_between_consecutive_stops.
