Top three things to fix
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.
Agencies here usually clear this within about 1 week (based on 5 observed fixes).
Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.
2894 of 3119 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.
Use mixed case for stop names and headsigns (e.g. 'Main St & 2nd Ave', not 'MAIN ST & 2ND AVE').
Some rider-facing names are in ALL CAPS or all lowercase. ALL-CAPS stop and headsign names are harder to read in apps and are read awkwardly by screen readers.
Effort: Often a bulk fix in your scheduling software.

FTA links the two on your P-50 form, so it is not a required feed change. We don't have your NTD ID on file, so this is not checked yet.
