TAD ligne Arrens-Marsous - Lourdes

Grade B · 90.0 / 100

First check for this agency, so there is no trend yet.

For this call: lead with the grade and the three fixes below, then confirm the feed is current and the rider information is complete. Each fix is framed as a next step, not a failure.

What changed since the last check

No category changes since the last check.

Top three things to fix

  1. Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.

    9 of 33 stops don't say whether a wheelchair user can board there. Riders who use wheelchairs can't plan a trip when accessibility is marked 'unknown'; apps show no information at all.

    Effort: A column in stops.txt; your scheduling software likely has it.

  2. Review the rule documentation for 'equal_shape_distance_diff_coordinates_distance_below_threshold' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

    Equal shape distance diff coordinates distance below threshold (flagged by the MobilityData validator). See the linked rule for what this affects.

    Effort: Varies.

  3. Review the rule documentation for 'stop_has_too_many_matches_for_shape' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

    Stop has too many matches for shape (flagged by the MobilityData validator). See the linked rule for what this affects.

    Effort: Varies.
