    Specification Compliance report

    12 notices reported (9 errors, 2 warnings, 1 infos)

    Notice Code Severity Total
    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.

    You can see more about this notice here.

    filename (?) The name of the faulty file. csvRowNumber (?) The row of the faulty record. fieldName (?) Faulty record's field name. fieldValue (?) Faulty value.
    "agency.txt" 2 "agency_url" "alco.transloc.com"
    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.

    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 ERROR 7

    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.
