invalid_url ERROR 1

invalid_url

A field contains a malformed URL.

Definitions for valid URLs are quite vague. We perform strict validation using the Apache Commons UrlValidator.

start_and_end_range_equal ERROR 7

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.

fast_travel_between_far_stops WARNING 27

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.
