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 578 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.

2. Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip.

   50 of 50 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.

   Effort: A default or per-trip field in your export.

3. Add fare_attributes.txt (or Fares v2 files) with your fare structure. If your service is fare-free, ask to have it marked fare-free instead.

   The feed contains no fare information. Riders see 'fare unknown' in trip planners and can't budget their trip; visitors are most affected.

   Effort: A small file for most flat-fare systems.

Hi Indian Trails, Detroit Ann Arbor Express team, Service data ended 578 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/indian-trails-detroit-ann-arbor-express/
