Madera County Transit

Grade C · 73.8 / 100

Unchanged since 2026-07-08.

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. 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.

    Estimated effort: Usually a vendor support ticket.

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

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

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

    Estimated effort: Usually a vendor support ticket.

    Agencies here usually clear this within about 1 week (based on 9 observed fixes).

  3. Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.

    34 of 35 stops don't say whether a wheelchair user can board there. Riders who use wheelchairs can't plan a trip when accessibility is marked 'unknown'; apps show no information at all.

    Estimated effort: A column in stops.txt; your scheduling software likely has it.

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.
