Top three things to fix

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

   6352 of 6355 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.

2. Add feed_info.txt with feed_start_date and feed_end_date to your export.

   feed_info.txt is missing its start/end dates (the file itself is absent) Apps and this scorecard can't warn anyone before the feed goes stale without stated validity dates.

   Effort: Two fields, set once in export settings.

3. Add the destination, direction, or 'via' label riders actually see to trip_headsign. Do not copy the route name. If the label changes during the trip, use stop_headsign.

   2999 of 6355 trips have no headsign, the text that tells riders where the bus is going. When a route has multiple directions or patterns, the route name alone may not tell riders which service is coming.

   Effort: Usually one value per route pattern in your scheduling source.

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): 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.
