  • 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, and set feed_info feed_end_date past your next service change.

    Service data ended 2381 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.

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

    Agencies here usually clear this within about 1 week (based on 18 observed fixes).

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

    Missing required column (flagged by the MobilityData validator). See the linked rule for what this affects.

    Effort: Varies.

  3. Re-generate shape distances in your export; flag to your vendor if it persists.

    Some trips have stop times whose distances along the route go backwards. Apps can show buses jumping backwards or mis-order stops.

    Effort: Usually an export-tool fix, not hand editing.

Ready to send to the agency

Hi Addison County Transit (ACTR) team, Service data ended 2381 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. The fix is usually one export setting: Re-export the feed with a calendar that reaches further out, and set feed_info feed_end_date past your next service change. Your feed is produced by Trillium, so the quickest path is usually forwarding this to your Trillium contact. This came from your GTFS data quality scorecard, which checks the feed you publish and lists the fixes in plain language: https://gtfsscorecard.org/agency/addison-county-transit-actr-543/
