The Bus
Grade B · 81.6 / 100
Unchanged since 2026-07-08.
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 'invalid_phone_number' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Invalid phone number (flagged by the MobilityData validator). See the linked rule for what this affects.
Estimated effort: Varies.
Populate trip_headsign to match what the bus displays.
188 of 280 trips have no headsign. Riders at the stop can't tell which direction a bus is going.
Estimated effort: Usually a bulk edit in your scheduling software.
Use mixed case for stop names and headsigns (e.g. 'Main St & 2nd Ave', not 'MAIN ST & 2ND AVE').
Some rider-facing names are in ALL CAPS or all lowercase. ALL-CAPS stop and headsign names are harder to read in apps and are read awkwardly by screen readers.
Estimated effort: Often a bulk fix in your scheduling software.
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.
