Top three things to fix
Review the rule documentation for 'missing_required_field' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Missing required field (flagged by the MobilityData validator). See the linked rule for what this affects.
Effort: Varies.
Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every terminal. A field survey can start with the busiest terminals.
18 of 18 terminals 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.
Add the destination, direction, or 'via' label riders actually see to trip_headsign. Do not copy the route name. If the label changes during the trip, use stop_headsign.
5020 of 5020 trips lack rider-facing destination or direction text. When a route has multiple directions or patterns, the route name alone may not tell riders which service is coming.
Effort: Usually one value per route pattern in your scheduling source.
