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 6 hours ago; last changed 12 hours ago.

Measured 3 of 4 score categories from the agency's own feed.

How we measured this

Confidence in this measurement: medium.

Realtime quality was not measured this run. It does not count against the grade.
The feed was downloaded from the agency's own URL.

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

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.

⏱ Varies.worth about +8 points

Fix 02

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 +6 points

Fix 03

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.

Beyond the grade

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

14 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (HD, OCA, SLAC, X Line, X Express AM, and more).
Consider: Adjust route_color or route_text_color so each pair clears 4.5:1. Often switching the text between black and white is enough.
143 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("1070 Arastradero Road @ Front Door", "1070 Arastradero Road @ Side Door", "1290 Page Mill Road @ Hanover Street", and more).
Consider: Add tts_stop_name with the spoken form, e.g. 'Main Street and Second Avenue', for the affected stops.
This feed models stations or entrances but has no pathways.txt and levels.txt.
Consider: Add pathways.txt connecting entrances, platforms, and elevators, and levels.txt for each floor, so the step-free route is described.

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.

Published Ready: Published at a public URL.
Valid Ready: Passes validation with no errors.
Current Ready: Service data covers the next 344 days.

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 764 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 Awarded

This feed earns the conformance mark: valid, current, and stating wheelchair access on nearly every stop and trip.

[![GTFS conformance mark](https://gtfsscorecard.org/data/artifacts/stanford-marguerite-shuttle-sms/mark.svg)](https://gtfsscorecard.org/agency/stanford-marguerite-shuttle-sms/)

Valid Met: Passes validation with no errors.
Current Met: Service data covers the next 344 days.
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.

Clears the Google and Apple Maps four-week coverage bar. This feed has 344 days of service ahead, clearing the four-week (28-day) window Maps asks for. No validator errors either, so riders keep seeing this agency in their trip planners; warnings lower the grade here but do not remove a feed from Maps.

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.

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 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

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

Correctness 84 / 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 100 / 100: The FTA National Transit Database expectation of a valid, current feed. Google Transit: an expired calendar drops the agency from Maps.
Rider experience 100 / 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.
