Call-prep brief · checked 2026-10-31

SolTrans (Solano County Transit)

Grade A · 92.4 / 100

Unchanged since 2026-10-30.

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

    67 of 309 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.

    Fixing this covers 67 of 309 stops, about 22% of them.

    Effort: A column in stops.txt; your scheduling software likely has it.

  2. Add feed_contact_email or feed_contact_url to feed_info.txt.

    feed_info.txt lists no contact email and no contact URL. Without a contact, apps like Google Maps can't reach you when they find a problem in the feed.

    This is a validator notice, and the validator decides what each instance covers, so no share of the network can be read from it here.

    Effort: One field, set once in export settings.

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

    Some route colors don't contrast with their text color. Route badges get hard to read, most of all for riders with low vision.

    This is a validator notice, and the validator decides what each instance covers, so no share of the network can be read from it here.

    Effort: One field per route.

Riders and need behind these fixes

  • No ridership snapshot was on hand when this was built, so annual rider-trips are not known.
  • California as a whole measures lower on transit need. That is a statewide reading, not one for this feed's service area. Source: US Census ACS 5-year 2022, statewide overlay, as of 2026-10-26.

These describe this feed only. They do not rank agencies, and they do not change the grade or the order of the fixes.

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.

Published Ready
Published at a public URL.
Valid Ready
Passes validation with no errors.
Current Ready
Service data covers the next 426 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 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. 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 to NTD ID 90232, and keep the feed value stable. Do not change it solely to make the two values equal.
