• Rider experience no change
• Realtime quality no change

Top three things to fix

1. Check the trip updates endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request.

   The trip updates realtime feed failed during sampling. When this feed is down, riders see scheduled times presented as if they were live.

   Effort: Usually a vendor support ticket.

   Agencies here usually clear this within about 1 week (based on 11 observed fixes).

2. Check the vehicle positions endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request.

   The vehicle positions realtime feed failed during sampling. When this feed is down, riders see scheduled times presented as if they were live.

   Effort: Usually a vendor support ticket.

   Agencies here usually clear this within about 1 week (based on 9 observed fixes).

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

   Stop too far from shape using user distance (flagged by the MobilityData validator). See the linked rule for what this affects.

   Effort: Varies.

   Agencies here usually clear this within about 1 week (based on 6 observed fixes).

NTD certification readiness: Ready

This feed looks ready for your NTD certification: published at a public URL, valid, and current. The official check is still your D-10 certification.

Published Ready

Published at a public URL.

Valid Ready

Passes validation with no errors.

Current Ready

Service data covers the next 184 days.

agency_id and NTD ID: Not checked yet. Setting your GTFS agency_id to your five-digit NTD ID is an optional way to line a feed up with its National Transit Database record. FTA links the two on your P-50 form, so it is not a required feed change. We don't have your NTD ID on file, so this is not checked yet.
