Grade A · 90.7 / 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 '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.

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

    Stop too far from shape using user distance (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).

  3. Check the flagged trips in your scheduling software; remove them or restore their missing stops.

    Some trips serve fewer than two stops. A trip with one stop can't be ridden; planners ignore it and it may signal an export problem.

    Effort: Worth a vendor question if it appears often.

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 187 days.

agency_id and NTD ID: Not checked yet. Setting your GTFS agency_id to your five-digit NTD ID is an optional way to line a feed up with its National Transit Database record. FTA links the two on your P-50 form, so it is not a required feed change. We don't have your NTD ID on file, so this is not checked yet.
