Top three things to fix
Check the trip updates endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request.
The trip updates realtime feed failed during sampling. When this feed is down, riders see scheduled times presented as if they were live.
Effort: Usually a vendor support ticket.
Review the rule documentation for 'block_trips_with_overlapping_stop_times' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Block trips with overlapping stop times (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 stop. A field survey can start with the busiest stops.
2131 of 2667 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.
