Connecticut Transit

Grade F · 54.9 / 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. 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.

    9613 of 9613 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. Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip.

    20490 of 20490 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.

NTD GTFS readiness: Ready

Published at a public URL, valid, current, and identified with agency_id: the four feed checks for RY2026 all hold here. Only your own D-10 and P-50 filings make that official; this is a heads-up, not a determination.

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 1, 5, 4, 2, 3, 7, 8; your National Transit Database ID is 10048. 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 1, 5, 4, 2, 3, 7, 8 to NTD ID 10048, and keep the feed value stable. Do not change it solely to make the two values equal.
