STAS (Saint-Étienne Métropole)
Grade F · 32.8 / 100
Unchanged since 2026-07-31.
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:
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.
Re-generate shape distances in your export; flag to your vendor if it persists.
Some trips have stop times whose distances along the route go backwards. Apps can show transit vehicles jumping backwards or mis-order stops.
Estimated effort: Usually an export-tool fix, not hand editing.
Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip.
23501 of 23501 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the transit vehicle itself can take them.
Estimated effort: A default or per-trip field in your export.
