Top three things to fix

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

    31 of 31 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.

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

    60 of 60 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).

  3. Populate trip_headsign to match what the bus displays.

    60 of 60 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.

NTD certification readiness: Ready

Published at a public URL, valid, and current: the three things the NTD GTFS requirement asks of a feed all hold here. Only your own D-10 certification makes that official; this is a heads-up, not a determination.

Service data covers the next 208 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.
