Top three things to fix
Review the rule documentation for 'foreign_key_violation' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Foreign key violation (flagged by the MobilityData validator). See the linked rule for what this affects.
Effort: Varies.
Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip.
254 of 254 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.
Effort: A default or per-trip field in your export.
Turn on 'remove unused shapes' (or the like) in your export tool.
The feed contains route shapes no trip uses. Harmless to riders, but it bloats the feed and suggests stale export data.
Effort: One setting.
