Grade B · 87.5 / 100
Unchanged since 2026-10-06.
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_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.
29 of 116 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.
Fixing this covers 29 of 116 stops, about 25% of them.
Estimated effort: A column in stops.txt; your scheduling software likely has it.
Remove retired stops from the export, or add them back to the trips that should serve them.
Some stops exist in the feed but no trip ever stops at them. Riders may walk to a stop where no bus is scheduled to arrive.
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: A review pass in your scheduling software.
Review the rule documentation for 'equal_shape_distance_diff_coordinates_distance_below_threshold' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Equal shape distance diff coordinates distance below threshold (flagged by the MobilityData validator). See the linked rule for what this affects.

Estimated effort: Varies.
Riders and need behind these fixes
- This feed carries no National Transit Database ID, so annual rider-trips are not known for it.
- North Carolina as a whole measures lower on transit need. That is a statewide reading, not one for this feed's service area. Source: US Census ACS 5-year 2022, statewide overlay, as of 2026-10-05.
These describe this feed only. They do not rank agencies, and they do not change the grade or the order of the fixes.
