Grade C · 73.5 / 100
First check for this agency, so there is no trend yet.
For this call: lead with the grade and the three fixes below, then confirm the feed is current and the rider information is complete. Each fix is framed as a next step, not a failure.
What changed since the last check
No category changes since the last check.
Top three things to fix
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.
Effort: Varies.
Add fare_attributes.txt (or Fares v2 files) with your fare structure. If your service is fare-free, ask to have it marked fare-free instead.
The feed contains no fare information. Riders see 'fare unknown' in trip planners and can't budget their trip; visitors are most affected.
Effort: A small file for most flat-fare systems.
Turn on shape cleanup in your export tool, or drop the repeated points from shapes.txt.
Some route lines list the same point twice in a row. Repeated points don't hurt riders, but they can skew distance math and hint at a shaky export.
Effort: Usually one export setting.
