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.

What needs attention next

Three improvements, in priority order, each sized so the board can see what it is approving:

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

   35 of 106 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.

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.

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

3. Review the rule documentation for 'route_short_name_too_long' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

   Route short name too long (flagged by the MobilityData validator). See the linked rule for what this affects.

   Estimated effort: Varies.

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.
