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:
Review the rule documentation for 'foreign_key_violation' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Foreign key violation (flagged by the MobilityData validator). See the linked rule for what this affects.
Estimated effort: Varies.
Ask your AVL vendor to publish updates at least every 20 seconds (the Caltrans guideline).
Realtime data was up to 607 seconds old when sampled. Stale positions and predictions are worse than none: riders watch a bus that already left.
Estimated effort: A vendor configuration question.
Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.
112 of 112 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.
