Call-prep brief · checked 2026-08-23

Gold Coast Transit, South Coast Area Transit

Grade F · 48.6 / 100

Unchanged since 2026-08-22.

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 no change

Top three things to fix

  1. 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 buses jumping backwards or mis-order stops.

    Effort: Usually an export-tool fix, not hand editing.

  2. Check with your AVL vendor that every vehicle assignment flows into TripUpdates, including school-day and tripper runs.

    28 of 28 trips scheduled during the sampling window had no live predictions. Riders on those trips get schedule data dressed up as realtime. Caltrans expects every operating trip in TripUpdates.

    Effort: A vendor data-mapping question.

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

    645 of 645 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.

NTD GTFS readiness: Needs attention

This feed is close to NTD-ready. 1 validator error to resolve.

Current Ready
Service data covers the next 132 days.
agency_id provided Ready
agency.txt provides agency_id. For RY2026, keep one stable value for each NTD reporter represented in the feed and crosswalk each value on the P-50 form.

agency_id equals NTD ID (optional): Different (allowed). Your feed's agency_id is GCT; your National Transit Database ID is 90035. A feed that serves several agencies (a shared regional feed) can legitimately carry more than one agency_id. The values do not need to equal the five-digit NTD ID, so this difference is allowed and carries no score. Confirm that P-50 crosswalks agency_id GCT to NTD ID 90035, and keep the feed value stable. Do not change it solely to make the two values equal.
