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 configured feed URL. Publisher ownership of that URL is not verified.

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

About this feed

Stanford Marguerite Shuttle (SMS)’s published feed lists 28 bus routes, 493 scheduled trips and 183 stops. Its service dates run from 2026-09-01 through 2027-09-26. The published file last changed on 2026-10-06.

Top things to fix

Fix 01

Remove retired stops from the export, or add them back to the trips that should serve them.Likely your export tool

Some stops exist in the feed but no trip ever stops at them. Riders may walk to a stop where no bus is scheduled to arrive.

This is a validator notice, and the validator decides what each instance covers, so no share of the network can be read from it here.

⏱ A review pass in your scheduling software.worth about +4 points in its category

Fix 02

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.

This is a validator notice, and the validator decides what each instance covers, so no share of the network can be read from it here.

⏱ A quick look at the flagged files.

Fix 03

Check whether the gap is real, like a seasonal break; if not, add the missing dates to the calendar.

The feed has a stretch of two weeks or more with no service running. A long gap can mean dates were left out of the calendar. Apps then show no trips on those days.

Riders and need behind these fixes

This feed carries no National Transit Database ID, so annual rider-trips are not known for it.
California as a whole measures lower on transit need. That is a statewide reading, not one for this feed's service area. Source: US Census ACS 5-year 2022, statewide overlay, as of 2026-10-05.

These describe this feed only. They do not rank agencies, and they do not change the grade or the order of the fixes.

Rider view: what this feed publishes

A quick read of rider-facing information in this feed.

Schedule visibility: The feed's last published service date is in 354 days.
Published accessibility data: Accessibility information is stated for 100% of stops and 100% of trips. This measures published data, not whether stops or vehicles are physically usable.
Fare information: Fare information is published using GTFS Fares v1.
Realtime information: Realtime-feed availability and live-arrival coverage are not known from this scorecard.

Important: This does not rate service reliability. Riders should confirm current service alerts, fares, and accessibility accommodations with the transit operator before traveling.

Send your vendor a fix request

You may not control the GTFS export yourself. Copy this and send it to whoever runs your scheduling software export. It names each fix with the validator notice and a guide link.

NTD GTFS readiness Ready

Published at a public URL, valid, current, and identified with agency_id: the four feed checks for RY2026 all hold here. Only your own D-10 and P-50 filings make 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 354 days.
agency_id provided Ready: agency.txt provides agency_id. For RY2026, keep one stable value for each NTD reporter represented in the feed and crosswalk each value on the P-50 form.

agency_id equals your NTD ID (optional) Not checked yet: This feed provides agency_id. For RY2026, keep one stable value for each NTD reporter represented in the feed and crosswalk it on the P-50 form. The value does not need to equal the five-digit NTD ID; we do not have that ID on file, so the optional equality comparison is not checked yet.

shapes.txt covers your trips Ready: All 493 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, provide a stable agency_id for each represented reporter, and confirm the feed and P-50 crosswalk each year. This box is a heads-up; your filings are the official check.

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). For RY2026, each represented reporter needs a stable agency_id, unique within the feed and crosswalked to its five-digit NTD ID on P-50; the values do not need to be equal. FTA also 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 354 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.

Can riders use it?

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

1 of 183 boardable stops are never served by any trip. Riders see these stops in apps and on the map but can never catch anything there, which erodes trust in the data. Remove stops no route serves, or add the trips that should call at them.

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.

Clears the Google and Apple Maps four-week coverage bar. This feed has 354 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

The scorecard is a data-quality lens, not a compliance determination. Its universal references describe good GTFS and useful rider information. Useful references here are GTFS Schedule Best Practices, GTFS-Realtime Best Practices, MobilityData grading scheme, Google Transit publication guidance, FTA National Transit Database GTFS requirement. 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.

Correctness 94 / 100: GTFS Schedule best practices, checked by the MobilityData validator. MobilityData grading covers stop locations, route names, and colors. Google Transit requires a feed to pass validation for publication. FTA NTD readiness also checks that the published feed is valid.
Freshness 100 / 100: GTFS Schedule best practices call for a dataset that stays current. An expired calendar can remove service from Google Transit and other rider trip planners. FTA NTD readiness also checks that the published feed is current.
Rider experience 100 / 100: GTFS Best Practices for rider-facing fields. MobilityData grading covers stop names and headsigns.
Realtime quality Not yet published: GTFS-Realtime best practices: a stable URL, high uptime, and frequent updates.

Cite this record

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/stanford-marguerite-shuttle-sms/2026-10-07.json and never overwritten, pinning the grade, category scores, rubric version, validator version, reader archive profile, and the scored feed's sha256 as they stood on 2026-10-07. Use it in a board packet, a regulatory filing, or a research citation instead of linking the live page, whose content will differ on your next visit.
