Top three things to fix

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

   Equal shape distance diff coordinates (flagged by the MobilityData validator). See the linked rule for what this affects.

   Effort: Varies.

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

   2334 of 2334 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).

   4123 of 4123 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).

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.
