Top three things to fix
Review the rule documentation for 'stop_time_with_arrival_before_previous_departure_time' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Stop time with arrival before previous departure time (flagged by the MobilityData validator). See the linked rule for what this affects.
Effort: Varies.
Review the rule documentation for 'start_and_end_range_out_of_order' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Start and end range out of order (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.
574 of 575 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.
