Auburn Transit

Grade D · 63.2 / 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 'missing_required_field' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

    Missing required field (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. Review the rule documentation for 'invalid_url' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

    Invalid url (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.

  3. Add the required column named in the finding to the flagged file.

    A file is missing a column that GTFS requires. Apps may reject the whole file, so riders could lose the affected routes or stops.

    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: Often an export setting; ask your vendor if it recurs.

Riders and need behind these fixes

  • This feed carries no National Transit Database ID, so annual rider-trips are not known for it.
  • California 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.
