Grade B · 80.5 / 100
Unchanged since 2026-08-22.
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:
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.
Check the flagged stop times for transposed minutes.
Some scheduled trips move faster between stops than a transit vehicle can. Usually a typo'd stop time; riders get arrival times no transit vehicle can meet.
Estimated effort: A few minutes per flagged trip.
Review the flagged fields and fill in the ones your riders would use.
Some files leave out fields that GTFS asks for but does not require. Recommended fields like agency_phone or stop descriptions make the feed more useful to riders and trip planners.
Estimated effort: A field at a time; not urgent.
