Top three things to fix
Review the rule documentation for 'missing_required_agency_id' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Missing required agency id (flagged by the MobilityData validator). See the linked rule for what this affects.
This is a validator notice, and the validator decides what each instance covers, so no share of the network can be read from it here.
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.
8900 of 8912 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.
Fixing this covers 8,900 of 8,912 trips, nearly all of them.
Effort: A default or per-trip field in your export.
Remove past service periods the next time you export the feed.
Some service calendars in the feed have already ended. Expired calendars are dead weight and can hide real schedule problems from your staff and vendors.
This is a validator notice, and the validator decides what each instance covers, so no share of the network can be read from it here.
Effort: One setting in most export tools.
Riders and need behind these fixes
- This feed carries no National Transit Database ID, so annual rider-trips are not known for it.
- Washington as a whole measures lower on transit need. That is a statewide reading, not one for this feed's service area. Source: US Census ACS 5-year 2022, statewide overlay, as of 2026-10-05.
These describe this feed only. They do not rank agencies, and they do not change the grade or the order of the fixes.
