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:
Ask your AVL vendor why the feed stopped advancing; the GTFS-Realtime header timestamp should move forward on every publish.
The realtime feed's last update was about 19 hours old when sampled. A realtime feed this far behind has effectively stopped. Riders see buses that already left, or apps quietly fall back to the schedule while still showing a live label.
Estimated effort: A vendor support ticket; treat it as a feed outage.
Re-generate shape distances in your export; flag to your vendor if it persists.
Some trips have stop times whose distances along the route go backwards. Apps can show buses jumping backwards or mis-order stops.
Estimated effort: Usually an export-tool fix, not hand editing.
Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.
125 of 125 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.
