C TRAN

Grade F · 37.2 / 100

Unchanged since 2026-07-31.

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. Re-export the feed with a calendar that reaches further out, and set feed_info feed_end_date past your next service change.

    Service data ended 1309 day(s) ago. When the calendar runs out, trip planners stop showing this agency even though the buses are still running. Riders are told the service does not exist.

    Effort: Usually one export setting; export on a schedule so it never lapses again.

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

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

    Effort: Varies.

  3. 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.

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.
