Duluth Transit

Grade F · 58.9 / 100

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

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

    19 of 19 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.

    Estimated effort: A vendor data-mapping question.

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

  2. 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.

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

  3. Set wheelchair_accessible on every trip (most small-agency fleets are 100% accessible, so this is often a single default).

    4385 of 4385 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: Often one default setting in your export.

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