decreasing_or_equal_stop_time_distance Two consecutive stop times in a trip should have increasing distance. If the values are equal, this is considered as an error. 127 113
feed_expiration_date At any time, the published GTFS dataset should be valid for at least the next 7 days, and ideally for as long as the operator is confident that the schedule will continue to be operated. If possible, the GTFS dataset should cover at least the next 30 days of service. 7 5
invalid_url A field contains a malformed URL. 2 2
more_than_one_entity A file that is expected to have only one row has more than one row. 1 1
