What changed since the last check

• Correctness no change
• Freshness down 1.7
• Rider experience no change

Top three things to fix

1. Populate trip_headsign to match what the bus displays.

   1814 of 2347 trips have no headsign. Riders at the stop can't tell which direction a bus is going.

   Effort: Usually a bulk edit in your scheduling software.

2. Remove retired stops from the export, or add them back to the trips that should serve them.

   Some stops exist in the feed but no trip ever stops at them. Riders may walk to a stop where no bus is scheduled to arrive.

   Effort: A review pass in your scheduling software.

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

3. Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.

   9 of 78 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.

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 65 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.
