• Freshness down 1.7
• Rider experience no change
• Realtime quality no change

Top three things to fix

1. Check with your AVL vendor that every vehicle assignment flows into TripUpdates, including school-day and tripper runs.

   19 of 19 trips scheduled during the sampling window had no live predictions. Riders on those trips get schedule data dressed up as realtime. Caltrans expects every operating trip in TripUpdates.

   Effort: A vendor data-mapping question.

   Agencies here usually clear this within about 1 week (based on 84 observed fixes).

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

   1510 of 1510 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.

3. Set wheelchair_accessible on every trip (most small-agency fleets are 100% accessible, so this is often a single default).

   4385 of 4385 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: Often one default setting in your export.

   Agencies here usually clear this within about 1 week (based on 5 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.

Passes validation with no errors.

Current Ready

Service data covers the next 63 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.
