Call-prep brief · checked 2026-08-01

Mendocino Transit Authority

Grade C · 70.9 / 100

Down 0.4 points since 2026-07-31 (C to C).

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

Top three things to fix

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

    246 of 246 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.

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

  2. Remove retired stops from the export, or add them back to the trips that should serve them.

    Some stops exist in the feed but no trip ever stops at them. Riders may walk to a stop where no bus is scheduled to arrive.

    Effort: A review pass in your scheduling software.

  3. Check the flagged stop times for transposed minutes.

    Some scheduled trips move faster between stops than a bus can. Usually a typo'd stop time; riders get arrival times no bus can meet.

    Effort: A few minutes per flagged trip.
