Saga Prefecture Route Bus (佐賀県 路線バス)
Grade F · 55.2 / 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
Add the required column named in the finding to the flagged file.
A file is missing a column that GTFS requires. Apps may reject the whole file, so riders could lose the affected routes or stops.
Effort: Often an export setting; ask your vendor if it recurs.
Ask your AVL vendor to check that every vehicle assignment reaches TripUpdates. School-day and tripper runs are the ones most often left out.
3 of 3 trips scheduled during the sampling window had no live predictions. Riders on those trips get schedule times labeled as live. Caltrans asks that every trip you run shows up in TripUpdates.
Effort: A vendor data-mapping question.
Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.
4003 of 4003 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.
Effort: A column in stops.txt; your scheduling software likely has it.
