Santa Maria Area Transit

Grade D · 64.2 / 100

Down 1.6 points since 2026-08-22 (D to D).

For this call: lead with the grade and the three fixes below, then confirm the feed is current and the NTD details line up. Each fix is framed as a next step, not a failure.

What changed since the last check

  • Correctness no change
  • Freshness no change
  • Rider experience no change
  • Realtime quality down 7.8

No longer reported since the last check (1 finding):

  • 2 of 6 trips scheduled during the sampling window had no live predictions. (scorecard_rt_trip_coverage)

This compares feed state. It does not identify who made a change or why.

Top three things to fix

  1. Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.

    290 of 290 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.

  2. Ask your AVL vendor to check vehicle-to-trip assignments for the flagged trips.

    11 of 13 sampled vehicle positions were far from their assigned route (worst: 10998 m). A bus shown off its route usually means a wrong trip assignment; riders watch their bus drive the wrong streets.

    Effort: A vendor support ticket with the trip ids attached.

  3. Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip.

    528 of 528 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.

    Effort: A default or per-trip field in your export.
