Top three things to fix
Ask your AVL vendor why the feed stopped advancing; the GTFS-Realtime header timestamp should move forward on every publish.
The realtime feed's last update was about 19 hours old when sampled. A realtime feed this far behind has effectively stopped. Riders see buses that already left, or apps quietly fall back to the schedule while still showing a live label.
Effort: A vendor support ticket; treat it as a feed outage.
Re-generate shape distances in your export; flag to your vendor if it persists.
Some trips have stop times whose distances along the route go backwards. Apps can show buses jumping backwards or mis-order stops.
Effort: Usually an export-tool fix, not hand editing.
Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.
125 of 125 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.
