Call-prep brief · checked 2026-07-09

Stanford Marguerite Shuttle (SMS)

Grade A · 92.9 / 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 'equal_shape_distance_same_coordinates' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

    Equal shape distance same coordinates (flagged by the MobilityData validator). See the linked rule for what this affects.

    Effort: Varies.

  2. Use mixed case for stop names and headsigns (e.g. 'Main St & 2nd Ave', not 'MAIN ST & 2ND AVE').

    Some rider-facing names are in ALL CAPS or all lowercase. ALL-CAPS stop and headsign names are harder to read in apps and are read awkwardly by screen readers.

    Effort: Often a bulk fix in your scheduling software.

  3. Check the flagged column names for misspellings of standard GTFS fields; remove them if they are vendor extras.

    Some files contain columns that are not part of the GTFS spec. Harmless to riders, but apps ignore these columns and they can hide typos in real column names.

    Effort: A quick look at the flagged files.

NTD certification readiness: Ready

Published at a public URL, valid, and current: the three things the NTD GTFS requirement asks of a feed all hold here. Only your own D-10 certification makes that official; this is a heads-up, not a determination.

Service data covers the next 345 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.

The bar this score answers to
