Call-prep brief · checked 2026-07-09

Bustang

Grade C · 73.4 / 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 'foreign_key_violation' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

    Foreign key violation (flagged by the MobilityData validator). See the linked rule for what this affects.

    Effort: Varies.

  2. Set wheelchair_accessible on every trip (most small-agency fleets are 100% accessible, so this is often a single default).

    254 of 254 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.

    Effort: Often one default setting in your export.

    Agencies here usually clear this within about 1 week (based on 5 observed fixes).

  3. Turn on 'remove unused shapes' (or the like) in your export tool.

    The feed contains route shapes no trip uses. Harmless to riders, but it bloats the feed and suggests stale export data.

    Effort: One setting.

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.
