C TRAN
Grade F · 37.2 / 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:
Re-export the feed with a calendar that reaches further out, and set feed_info feed_end_date past your next service change.
Service data ended 1286 day(s) ago. When the calendar runs out, trip planners stop showing this agency even though the buses are still running. Riders are told the service does not exist.
Estimated effort: Usually one export setting; export on a schedule so it never lapses again.
Agencies here usually clear this within about 1 week (based on 18 observed fixes).
Review the rule documentation for 'trip_distance_exceeds_shape_distance' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.
Trip distance exceeds shape distance (flagged by the MobilityData validator). See the linked rule for what this affects.
Estimated effort: Varies.
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.
Agencies here usually clear this within about 1 week (based on 16 observed fixes).
