Grade C · 76.1 / 100
Unchanged since 2026-09-12.
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:
Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip.
6352 of 6355 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: A default or per-trip field in your export.
Add feed_info.txt with feed_start_date and feed_end_date to your export.
feed_info.txt is missing its start/end dates (the file itself is absent) Apps and this scorecard can't warn anyone before the feed goes stale without stated validity dates.
Estimated effort: Two fields, set once in export settings.
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 have no headsign, the text that tells riders where the bus is going. 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.
