Grade A · 92.6 / 100

Unchanged since 2026-08-22.

What this grade measures

The quality of the schedule data in the feed scored here 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. Add the destination, direction, or 'via' label riders actually see to trip_headsign. Do not copy the route name. If the label changes during the trip, use stop_headsign.

    2999 of 6355 trips lack rider-facing destination or direction text. When a route has multiple directions or patterns, the route name alone may not tell riders which service is coming.

    Estimated effort: Usually one value per route pattern in your scheduling source.

  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.

    Estimated effort: A review pass in your scheduling software.

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

    14 of 83 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.
