A data-quality and completeness lens to help an agency improve its GTFS feed. Not an official compliance determination from any transit program. New to this? How to read your scorecard. Interactive view of this scorecard. Rubric v1.1, validator 8.0.1.

Checked for changes 12 minutes ago; last fetch returned HTTP 404.

Measured 3 of 4 score categories from the Mobility Database's mirror copy of the feed.

How we measured this

Confidence in this measurement: provisional.

Confidence describes how much the pipeline could measure this run, not the feed itself. It never changes the grade.

Top things to fix

Fix 01

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

Service data ended 54 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.

⏱ Usually one export setting; export on a schedule so it never lapses again.worth about +100 points

Agencies here usually clear this within about 1 week (based on 18 observed fixes).

Fix 02

Add fare_attributes.txt (or Fares v2 files) with your fare structure. If your service is fare-free, ask to have it marked fare-free instead.

The feed contains no fare information. Riders see 'fare unknown' in trip planners and can't budget their trip; visitors are most affected.

⏱ A small file for most flat-fare systems.worth about +15 points

Fix 03

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

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.

⏱ Often a bulk fix in your scheduling software.worth about +8 points

Close the loop on each fix. Read the guide, make the change in your tool, and let the next run verify it — the scorecard shows the fix; the agency publishes it.

Score by category

Correctness72.0 / 100

The MobilityData validator flagged 6 kinds of issue across 428 instances (0 error, 428 warning, 0 informational).

Freshness0.0 / 100

Service data ended 54 day(s) ago. Trip planners have likely already dropped this feed.

Rider experience77.5 / 100

100% of stops state wheelchair accessibility (67% marked accessible, 33% marked not accessible). This measures what the feed publishes, not whether a stop is physically usable. Fare data is not published.

Accessibility100 / 100

100% of stops state accessibility (67% marked accessible). Reflects what the feed states, not verified physical usability.

Everything we checked

Beyond the grade

Opportunities that do not change your grade today: fare detail, on-demand service, and deeper accessibility data.

NTD certification readiness Not ready

Resolve this before you certify on the D-10. Service data expired 54 days ago, so FTA would find the link out of date.

Published Ready
Published at a public URL.
Valid Ready
Passes validation with no errors.
Current Not ready
Service data expired 54 days ago, so FTA would find the link out of date.
agency_id matches your 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.
shapes.txt covers your trips Ready
All 5605 trips have a shape in shapes.txt.

In plain words: if you report to the federal transit database, you have to publish a working, up-to-date feed and confirm it once a year. This box is a heads-up on whether yours looks ready; it is not the official sign-off.

A readiness signal mapping this feed to the FTA National Transit Database GTFS requirement (Report Year 2023 onward: a public, valid, current feed, certified annually on the D-10). Aligning agency_id with your NTD ID lets the feed line up with your NTD record; the July 2025 final rule links the two on the P-50 form rather than requiring that feed change, and requires shapes.txt in the published GTFS: Full Reporters from Report Year 2025, and Reduced, Rural, and Tribal Reporters from Report Year 2026. Not an official determination; your certification is the official check.

Conformance mark Not yet

This feed is close to the conformance mark. Service data expired 54 days ago.

Valid Met
Passes validation with no errors.
Current Not yet
Service data expired 54 days ago.
Accessible Met
States wheelchair access on 100% of stops and 100% of trips.

In plain words: earn this mark when your feed passes validation, has not expired, and says whether nearly every stop and trip is wheelchair accessible.

A pass credential for a feed that is valid, current, and states wheelchair access on nearly every stop and trip. Accessibility here measures what the feed publishes, not whether a stop is physically usable. How the conformance mark works.

How this agency maps to the standards

A data-quality lens, not a compliance determination. Each category shows this feed's score and the standards it relates to: the FTA National Transit Database GTFS requirement, the MobilityData grading scheme, and the Google Transit gate. Read the full standards crosswalk.

Correctness 72 / 100
GTFS Schedule best practices, checked by the MobilityData validator. MobilityData grading: stop locations, route names and colors. Google Transit: a feed must pass validation to stay in Maps.
Freshness 0 / 100
The FTA National Transit Database expectation of a valid, current feed. Google Transit: an expired calendar drops the agency from Maps.
Rider experience 78 / 100
GTFS Best Practices for rider-facing fields. MobilityData grading: stop names and headsigns.
Realtime quality Not yet published
GTFS-Realtime best practices: a stable URL, high uptime, and frequent updates.

This page updates on every check. The record below does not: it is the dated file this grade came from, published at https://gtfsscorecard.org/data/artifacts/suntran-2354/2026-07-09.json and never overwritten, pinning the grade, category scores, rubric version, validator version, and the scored feed's sha256 as they stood on 2026-07-09.
