Unchanged since 2026-10-06.

For this call: lead with the grade and the three fixes below, then confirm the feed is current and the NTD details line up. Each fix is framed as a next step, not a failure.

What changed since the last check

  • Correctness no change
  • Freshness no change
  • Rider experience no change

Top three things to fix

  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.

    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.

    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.

    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.
