Simi Valley Transit

Grade F · 56.6 / 100

Unchanged since 2026-07-31.

What this grade measures

The quality of the schedule data this agency publishes 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. Re-export the feed with a calendar that reaches further out, and set feed_info feed_end_date past your next service change.

    Service data ended 1157 day(s) ago. When the calendar runs out, trip planners stop showing this agency even though the buses are still running. Riders are told the service does not exist.

    Estimated effort: Usually one export setting; export on a schedule so it never lapses again.

  2. 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.

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

  3. Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip.

    129 of 129 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.

    Estimated effort: A default or per-trip field in your export.

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.
