Grade F · 54.9 / 100

Down 0.3 points since 2026-07-08 (F to F).

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 down 1.7
  • Rider experience no change
  • Realtime quality no change

Top three things to fix

  1. Check the trip updates endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request.

    The trip updates realtime feed failed during sampling. When this feed is down, riders see scheduled times presented as if they were live.

    Effort: Usually a vendor support ticket.

    Agencies here usually clear this within about 1 week (based on 11 observed fixes).

  2. Check the service alerts endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request.

    The service alerts realtime feed failed during sampling. When this feed is down, riders see scheduled times presented as if they were live.

    Effort: Usually a vendor support ticket.

    Agencies here usually clear this within about 1 week (based on 5 observed fixes).

  3. Check with your AVL vendor that every vehicle assignment flows into TripUpdates, including school-day and tripper runs.

    80 of 80 trips scheduled during the sampling window had no live predictions. Riders on those trips get schedule data dressed up as realtime. Caltrans expects every operating trip in TripUpdates.

    Effort: A vendor data-mapping question.

    Agencies here usually clear this within about 1 week (based on 84 observed fixes).

NTD certification readiness: Ready

This feed looks ready for your NTD certification: published at a public URL, valid, and current. The official check is still your D-10 certification.

agency_id and NTD ID: Not checked yet. Setting your GTFS agency_id to your five-digit NTD ID is an optional way to line a feed up with its National Transit Database record. FTA links the two on your P-50 form, so it is not a required feed change. We don't have your NTD ID on file, so this is not checked yet.
