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

  • Correctness no change
  • Freshness no change
  • Rider experience no change

Top three things to fix

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

    Duplicate key (flagged by the MobilityData validator). See the linked rule for what this affects.

    This is a validator notice, and the validator decides what each instance covers, so no share of the network can be read from it here.

    Effort: Varies.

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

    Stop time with arrival before previous departure time (flagged by the MobilityData validator). See the linked rule for what this affects.

    This is a validator notice, and the validator decides what each instance covers, so no share of the network can be read from it here.

    Effort: Varies.

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

    6530 of 6530 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.

    Fixing this covers all 6,530 stops in the feed.

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

Riders and need behind these fixes

  • Rider-trip figures come from the United States National Transit Database, which does not cover this feed's country.
  • The served-area need overlays cover the United States and Canada, so none of them applies to this feed.

These describe this feed only. They do not rank agencies, and they do not change the grade or the order of the fixes.
