Philly PHLASH

Grade A · 95.0 / 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. Set wheelchair_accessible on every trip (most small-agency fleets are 100% accessible, so this is often a single default).

    645 of 661 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).

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

    Big gap in service (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 13 observed fixes).

  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

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 343 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.
