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 2381 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

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

Missing required column (flagged by the MobilityData validator). See the linked rule for what this affects.

⏱ Varies.worth about +12 points

Fix 03

Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.Likely your team

93 of 93 stops don't say whether a wheelchair user can board there. Riders who use wheelchairs can't plan a trip when accessibility is marked 'unknown'; apps show no information at all.

⏱ A column in stops.txt; your scheduling software likely has it.worth about +25 points

NTD certification readiness Not ready

Resolve this before you certify on the D-10. 1 validator error to resolve. Service data expired 2381 days ago, so FTA would find the link out of date.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.

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. 1 validator error to resolve. Service data expired 2381 days ago. States wheelchair access on 0% of stops and 0% of trips; the mark needs 90% of each.

Valid Not yet
1 validator error to resolve.
Current Not yet
Service data expired 2381 days ago.
Accessible Not yet
States wheelchair access on 0% of stops and 0% of trips; the mark needs 90% of each.

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.

Can riders use it?

Checks beyond structural validation: places where the feed is valid but a rider still could not travel.

These do not change the grade. They catch trips with no rideable leg and stops no trip serves, the kind of gap a trip planner trips over.

Below the Google and Apple Maps four-week coverage bar. This feed's last day of service has passed, so Google and Apple Maps will stop showing your agency. Re-export with a calendar that covers at least the next four weeks. The feed also carries 2 validator errors, the other thing Maps checks at onboarding; the findings below name each fix.

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.

In California, the published guideline is California Transit Data Guidelines. Caltrans' published quality guidelines and compliance checklist; this rubric is anchored to them.

California Minimum GTFS Guidelines checklist (3 of 5 measured items met)

The state's own Data Process Checklist, matched item by item to what this scorecard already measures. An item marked "not measured here" is real ground the checklist covers that this tool does not check; see the official checklist for the full picture.

  • Meets Publish GTFS Schedule at a stable, automatically-fetchable URL

    The published feed URL downloaded at the last check.

  • Not measured here Implement required fields: Fares v2, text-to-speech stop names, shapes.txt, wheelchair_boarding, and Pathways where applicable

    This scorecard measures wheelchair_boarding, shapes.txt coverage, fare data, and station pathways separately, below; it does not check the Fares v2 format specifically or text-to-speech stop names.

  • Not measured here Achieve a passing score in every category of the MobilityData GTFS Grading Scheme v1

    This scorecard automates a proxy for the Grading Scheme's rider-facing fields (see the standards crosswalk) rather than running the scheme itself, which grades by comparison to the real world by hand.

  • Not measured here Publish changes to the base schedule at least one week ahead of every service change

    This scorecard does not track a feed's publish history, so advance notice cannot be checked.

  • Gap Produce no critical errors in the MobilityData GTFS Validator

    1 validator error to resolve.

  • Not measured here Publish Trip Updates, Vehicle Positions, and Alerts feeds

    This scorecard checks realtime reachability and freshness overall; it does not check for all three feed types individually.

  • Not measured here Update Trip Updates and Vehicle Positions at least every 20 seconds

    This scorecard samples realtime freshness; it does not check this specific 20-second cadence.

  • Not measured here Publish information for at least 99% of vehicles in service

    This scorecard measures the share of scheduled trips represented in TripUpdates, a related but different figure than vehicle coverage.

  • Not measured here Keep 100% of trip_ids consistent between Schedule and Realtime

    This scorecard does not currently check trip_id consistency between the Schedule and Realtime feeds.

  • Not measured here Produce no critical errors in the Center for Urban Transportation Research realtime validator

    This scorecard does not run the CUTR realtime validator.

  • Not measured here Publish accessible feed links on the agency or regional partner website

    This scorecard does not check the agency's own website.

  • Not measured here Register GTFS and GTFS-Realtime feeds with transit.land and the Mobility Database

    This scorecard does not currently check aggregator registration for this section.

  • Meets Designate a technical contact in feed_info.txt's feed_contact_email

    feed_info.txt states a technical contact.

  • Gap wheelchair_boarding stated on stops and trips

    States wheelchair access on 0% of stops and 0% of trips.

  • Not measured here shapes.txt with a shape for every trip

    Shape coverage has not been measured for this feed.

  • Meets Fare data published, or the service marked fare-free

    Fare data is published.

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/duarte-transit-105/2026-07-09.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.
