The Bus

Grade B · 81.6 / 100

Unchanged since 2026-10-06.

What this grade measures

The quality of the schedule data in the feed scored here for trip-planning apps: whether riders using Google Maps, Apple Maps, or Transit see current, correct, and complete information. It measures the data feed, not service quality or operations.

Progress this period

No newly cleared items this period. The score and trend above reflect where the feed stands today.

What needs attention next

Three improvements, in priority order, each sized so the board can see what it is approving:

  1. 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.

    Estimated effort: Varies.

  2. 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.

    Estimated effort: Usually one value per route pattern in your scheduling source.

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.

Trillium produces and hosts this feed as a service. These changes are made on their side: send the fix list to your Trillium contact and they apply it and republish.
