Top three things to fix
Review the rule documentation for 'invalid_phone_number' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Invalid phone number (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.
Add the destination, direction, or 'via' label riders actually see to trip_headsign. Do not copy the route name. If the label changes during the trip, use stop_headsign.
188 of 280 trips have no headsign, the text that tells riders where the transit vehicle is going. A trip counts when it has trip_headsign or a stop_headsign at every stop. When a route has multiple directions or patterns, the route name alone may not tell riders which service is coming.
Fixing this covers 188 of 280 trips, about 67% of them.
Effort: Usually one value per route pattern in your scheduling source.
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.
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: Often a bulk fix in your scheduling software.
Riders and need behind these fixes
- This feed carries no National Transit Database ID, so annual rider-trips are not known for it.
- Alaska 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.
