Call-prep brief · checked 2026-10-15

Yolé (Challans)

Grade F · 42.6 / 100

Unchanged since 2026-10-14.

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. Re-export the feed with a calendar that reaches further out. Set feed_end_date in feed_info.txt past your next service change.

    Service data ended 15 day(s) ago. When the calendar runs out, trip planners stop showing this agency even though the buses are still running. Riders are told the service does not exist.

    This one is about the feed as a whole, so there is no share of it to count.

    Effort: Usually one export setting; export on a schedule so it never lapses again.

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

    Missing required file (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. Review the rule documentation for 'invalid_input_files_in_subfolder' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

    Invalid input files in subfolder (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.

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.
