Grade A · 95.1 / 100
Unchanged since 2026-10-21.
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:
Check the flagged stops' shape_dist_traveled against the route shape, and re-generate it on export if they disagree.
Some stops sit far from the route line, going by the feed's own distance values. Trip planners may draw the route down the wrong path or point riders to the wrong boarding location.
This is a validator notice, and the validator decides what each instance covers, so no share of the network can be read from it here.
Estimated effort: Usually an export-tool fix, not hand editing.
Turn on 'remove unused shapes' (or the like) in your export tool.
The feed contains route shapes no trip uses. Harmless to riders, but it bloats the feed and suggests stale export data.

Estimated effort: One setting.
Check the flagged column names for misspellings of standard GTFS fields; remove them if they are vendor extras.
Some files contain columns that are not part of the GTFS spec. Harmless to riders, but apps ignore these columns and they can hide typos in real column names.

Riders and need behind these fixes
- Rider-trip figures come from the United States National Transit Database, which does not cover this feed's country.
- The served-area need overlays cover the United States and Canada, so none of them applies to this feed.
These describe this feed only. They do not rank agencies, and they do not change the grade or the order of the fixes.
