Top three things to fix
Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.
739 of 739 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.
Add fare_attributes.txt (or Fares v2 files) with your fare structure. If your service is fare-free, ask to have it marked fare-free instead.
The feed contains no fare information. Riders see 'fare unknown' in trip planners and can't budget their trip; visitors are most affected.
Effort: A small file for most flat-fare systems.
Review the rule documentation for 'unsorted_stop_times' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Unsorted stop times (flagged by the MobilityData validator). See the linked rule for what this affects.
Effort: Varies.
