• 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 555 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 'stop_time_timepoint_without_times' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

   Stop time timepoint without times (flagged by the MobilityData validator). See the linked rule for what this affects.

   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.

   538 of 538 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.

Ready to send to the agency

Hi Chapel Hill Transit (CHT) team, Service data ended 555 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/chapel-hill-transit-cht/

NTD certification readiness: Not ready

Resolve this before you certify on the D-10. 1 validator error to resolve. Service data expired 543 days ago, so FTA would find the link out of date.

agency_id and NTD ID: Not aligned. Your feed's agency_id is 243; your National Transit Database ID is 40051. A feed that serves several agencies (a shared regional feed) can legitimately carry more than one agency_id, so a difference here is a heads-up, not an error. Optionally set the agency_id for your service to 40051 in agency.txt (and the matching agency_id in routes.txt) so the feed lines up with your NTD record. It is a convenience, not a required feed change: FTA also links agency_id to your NTD ID on your P-50 form.
