Call-prep brief · checked 2026-07-09

SolTrans (Solano County Transit)

Grade A · 94.1 / 100

Unchanged since 2026-07-08.

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

Top three things to fix

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

    Missing feed contact email and url (flagged by the MobilityData validator). See the linked rule for what this affects.

    Effort: Varies.

    Agencies here usually clear this within about 1 week (based on 6 observed fixes).

  2. Pick a darker/lighter route_text_color for the flagged routes.

    Some route colors don't contrast with their text color. Route badges become unreadable, especially for riders with low vision.

    Effort: One field per route.

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

    3 of 327 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 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 552 days.

agency_id and NTD ID: Not aligned. Your feed's agency_id is 1; your National Transit Database ID is 90232. 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 90232 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.
