Duluth Transit

Grade F · 51.2 / 100

Down 0.4 points since 2026-07-31 (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 1.6
  • Rider experience no change
  • Realtime quality no change

Top three things to fix

  1. Re-export with a validity window that reaches at least 60 days out.

    Service data runs out in 28 day(s). When the calendar runs out, trip planners stop showing this agency. Fixing it now is calmer than after riders notice.

    Effort: One export setting.

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

    1 of 1 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.

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

    1510 of 1510 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.
