What changed since the last check

• Correctness no change
• Freshness down 1.6
• Rider experience no change

Top three things to fix

1. Use mixed case for stop names and headsigns (e.g. 'Main St & 2nd Ave', not 'MAIN ST & 2ND AVE').

   Some rider-facing names are in ALL CAPS or all lowercase. ALL-CAPS stop and headsign names are harder to read in apps and are read awkwardly by screen readers.

   Effort: Often a bulk fix in your scheduling software.

2. Review the rule documentation for 'trip_distance_exceeds_shape_distance_below_threshold' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

   Trip distance exceeds shape distance below threshold (flagged by the MobilityData validator). See the linked rule for what this affects.

   Effort: Varies.

3. Remove past service periods the next time you export the feed.

   Some service calendars in the feed have already expired. Expired calendars are dead weight and can hide real schedule problems from your staff and vendors.

   Effort: One setting in most export tools.

   Agencies here usually clear this within about 1 week (based on 61 observed fixes).

NTD certification readiness: Ready

This feed looks ready for your NTD certification: published at a public URL, valid, and current. The official check is still your D-10 certification.

Published Ready

Published at a public URL.

Valid Ready

Passes validation with no errors.

Current Ready

Service data covers the next 43 days.

agency_id and NTD ID: Not aligned. Your feed's agency_id is VTA; your National Transit Database ID is 90013. A feed that serves several agencies (a shared regional feed) can legitimately carry more than one agency_id, so a difference here is a heads-up, not an error. Optionally set the agency_id for your service to 90013 in agency.txt (and the matching agency_id in routes.txt) so the feed lines up with your NTD record. It is a convenience, not a required feed change: FTA also links agency_id to your NTD ID on your P-50 form.
