Call-prep brief · checked 2026-08-01

Clark County Public Transportation Benefit Area

Grade C · 77.7 / 100

Up 7.8 points since 2026-07-31 (D to C).

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 down 1.7
  • Rider experience no change
  • Realtime quality up 40.4

Top three things to fix

  1. Check the vehicle positions endpoint with your AVL vendor; it should return a fresh GTFS-Realtime protobuf on every request.

    The vehicle positions realtime feed failed during sampling. When this feed is down, riders see scheduled times presented as if they were live.

    Effort: Usually a vendor support ticket.

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

    910 of 914 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.

  3. Delete the empty calendars or set their service days.

    Some service calendars have no days of the week switched on. Trips tied to these calendars never run; they are dead data that can mask real schedule problems.

    Effort: A few minutes in your scheduling software.

agency_id equals NTD ID (optional): Not checked yet. This feed provides agency_id. For RY2026, keep one stable value for each NTD reporter represented in the feed and crosswalk it on the P-50 form. The value does not need to equal the five-digit NTD ID; we do not have that ID on file, so the optional equality comparison is not checked yet.
