Call-prep brief · checked 2026-10-12

Nasu Town Community Bus (那須町町民バス)

Grade C · 75.3 / 100

Unchanged since 2026-10-11.

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

  • Correctness no change
  • Freshness no change
  • Rider experience no change

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.

    116 of 116 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.

    Fixing this covers all 116 stops in the feed.

    Effort: A column in stops.txt; your scheduling software likely has it.

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

    12 of 12 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.

    Fixing this covers all 12 trips in the feed.

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

  3. Only change the flagged IDs if an app needs basic ASCII values. Update each place that uses the ID. Keep all names and headsigns in their original language.

    Some internal IDs use characters outside the basic text set. These IDs are valid UTF-8 data. This warning is only about support in older apps. It does not mean that names in other languages are wrong.

    This is a validator notice, and the validator decides what each instance covers, so no share of the network can be read from it here.

    Effort: A planned ID change, not a quick text cleanup.

Riders and need behind these fixes

  • Rider-trip figures come from the United States National Transit Database, which does not cover this feed's country.
  • The served-area need overlays cover the United States and Canada, so none of them applies to this feed.

These describe this feed only. They do not rank agencies, and they do not change the grade or the order of the fixes.
