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 4

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.

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.
