Score by category
The MobilityData validator flagged 6 kinds of issue across 67 instances (6 error, 61 warning, 0 informational).
Service data ended 2382 day(s) ago. Trip planners have likely already dropped this feed.
0% of stops state wheelchair accessibility (0% marked accessible, 0% marked not accessible). This measures what the feed publishes, not whether a stop is physically usable. Fare data is published.
0% of stops state accessibility (0% marked accessible). Reflects what the feed states, not verified physical usability.

- Error6 instances
Invalid date (flagged by the MobilityData validator).
See the linked rule for what this affects.
Fix: Review the rule documentation for 'invalid_date' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)
Validator rule: invalid_date · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Error1 instance
Service data ended 2382 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.
Fix: Re-export the feed with a calendar that reaches further out, and set feed_info feed_end_date past your next service change. (Usually one export setting; export on a schedule so it never lapses again.)
Agencies here usually clear this within about 1 week (based on 18 observed fixes).

1174 of 1174 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.
Fix: Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops. (A column in stops.txt; your scheduling software likely has it.)

- Warning51 instances
Some scheduled trips travel implausibly fast between stops.
Usually a typo'd stop time; riders get impossible arrival estimates.
Fix: Check the flagged stop times for transposed minutes. (A few minutes per flagged trip.)
Agencies here usually clear this within about 2 weeks (based on 6 observed fixes).
Validator rule: fast_travel_between_consecutive_stops · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning6 instances
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.
Fix: Use mixed case for stop names and headsigns (e.g. 'Main St & 2nd Ave', not 'MAIN ST & 2ND AVE'). (Often a bulk fix in your scheduling software.)
Validator rule: mixed_case_recommended_field · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning2 instances
Some files are missing recommended (not required) fields.
Recommended fields like agency_phone or stop descriptions make the feed more useful to riders and trip planners.
Fix: Review the flagged fields and fill in the ones your riders would use. (A field at a time; not urgent.)
Agencies here usually clear this within about 2 weeks (based on 8 observed fixes).
Validator rule: missing_recommended_field · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
This feed's service calendar runs out within the next 7 days.
When the calendar ends, Google Maps and other trip planners drop your agency entirely. Riders see no service at all.
Fix: Export and publish an updated GTFS feed that covers at least the next 30 days of service. (Usually a re-export from your scheduling software.)
Agencies here usually clear this within about 1 week (based on 16 observed fixes).

- Info1 instance
feed_info.txt has no technical contact (feed_contact_email or feed_contact_url).
App makers and state data programs have nobody to email when they spot a problem with your feed, so problems linger.
Fix: Add feed_contact_email to feed_info.txt. (One field.)
Agencies here usually clear this within about 1 week (based on 10 observed fixes).

Beyond the grade
Opportunities that do not change your grade today: fare detail, on-demand service, and deeper accessibility data.
8 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (2, 4, 5, 6, 10, 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.
52 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("Church at 3rd", "SBD Saginaw at 1st", "EBD Court at Dort SW", and more).
Consider: Add tts_stop_name with the spoken form, e.g. 'Main Street and Second Avenue', for the affected stops.
NTD certification readiness Not ready
Resolve this before you certify on the D-10. 1 validator error to resolve. Service data expired 2382 days ago, so FTA would find the link out of date.
- Published Ready
- Published at a public URL.
- Valid Needs attention
- 1 validator error to resolve.
- Current Not ready
- Service data expired 2382 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 2382 days ago. States wheelchair access on 0% of stops and 100% of trips; the mark needs 90% of each.
- Valid Not yet

- Current Not yet
- Service data expired 2382 days ago.
- Accessible Not yet
- States wheelchair access on 0% of stops and 100% 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.
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 6 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.
Your state runs a transit-data program that can help: Michigan Public Transit Open Data Program. MDOT's program helping agencies produce and maintain GTFS and GTFS-Flex. Your state publishes no quality rubric of its own, so the closest published bars a program can hold this feed to are the federal and industry ones below; the score maps to those.
- Correctness 56 / 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 68 / 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.
