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 v1.3, validator 8.0.1.
Checked for changes 1 days ago.
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.
- Realtime quality was not measured this run. It does not count against the grade.
- The agency's own feed URL was unreachable, so the Mobility Database's hosted mirror copy was scored instead.
Confidence describes how much the pipeline could measure this run, not the feed itself. It never changes the grade.
Top things to fix
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 1554 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 in its category
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 in its category
Turn on 'remove unused shapes' (or the like) in your export tool.Likely your export tool
The feed contains route shapes no trip uses. Harmless to riders, but it bloats the feed and suggests stale export data.
⏱ One setting.worth about +8 points in its category

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 was 1554 days ago.
- Published accessibility data
- Accessibility information is stated for 90.4% of stops and 100% of trips. This measures published data, not whether stops or vehicles are physically usable.
- Fare information
- No fare information is published in the feed.
- 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.

Score by category
The MobilityData validator flagged 11 kinds of issue across 258 instances (0 error, 108 warning, 150 informational).
Service data ended 1554 day(s) ago. Trip planners have likely already dropped this feed.
90% of stops state wheelchair accessibility (0% marked accessible, 90% marked not accessible). This measures what the feed publishes, not whether a stop is physically usable. Fare data is not published.
90% of stops state accessibility (0% marked accessible). Reflects what the feed states, not verified physical usability.
2 accessibility depth signals
3 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (DD, NE, WS).
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.
27 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("Green Rd Park & Ride Inbound", "Green Rd Park & Ride Outbound", "East Ann Arbor Health & Geriatrics Center", and more).
Consider: Add tts_stop_name with the spoken form, e.g. 'Main Street and Second Avenue', for the affected stops.
Opportunities to strengthen the data, not deductions from the sub-score above. States what the second accessibility lens can check from the feed, not verified physical usability.

- Error1 instance
Service data ended 1554 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.)
Finding code: scorecard_feed_expired · Read the fix guide · See GTFS Best Practices (opens GTFS Best Practices on an external site)
- Warning68 instances
The feed contains route shapes no trip uses.
Harmless to riders, but it bloats the feed and suggests stale export data.
Fix: Turn on 'remove unused shapes' (or the like) in your export tool. (One setting.)
Finding code: unused_shape · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning23 instances
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.
Fix: Remove retired stops from the export, or add them back to the trips that should serve them. (A review pass in your scheduling software.)
Finding code: stop_without_stop_time · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning13 instances
13 of 135 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.)
Finding code: scorecard_wheelchair_boarding_unknown · Read the fix guide · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)
- Warning7 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.)
Finding code: mixed_case_recommended_field · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning5 instances
Some service calendars in the feed have already ended.
Expired calendars are dead weight and can hide real schedule problems from your staff and vendors.
Fix: Remove past service periods the next time you export the feed. (One setting in most export tools.)
Finding code: expired_calendar · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning2 instances
Some route colors don't contrast with their text color.
Route badges get hard to read, most of all for riders with low vision.
Fix: Pick a darker/lighter route_text_color for the flagged routes. (One field per route.)
Finding code: route_color_contrast · 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.)
Finding code: feed_expiration_date7_days · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
feed_info.txt lists no contact email and no contact URL.
Without a contact, apps like Google Maps can't reach you when they find a problem in the feed.
Fix: Add feed_contact_email or feed_contact_url to feed_info.txt. (One field, set once in export settings.)
Finding code: missing_feed_contact_email_and_url · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
Many of the feed's trips don't run at all in the next 7 days.
It usually means old service periods are still in the export, making the feed bigger and harder to check.
Fix: Trim past service periods the next time you export. (One setting in most export tools.)
Finding code: trip_coverage_not_active_for_next7_days · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
The feed contains no fare information.
Riders see 'fare unknown' in trip planners and can't budget their trip; visitors are most affected.
Fix: 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. (A small file for most flat-fare systems.)
Finding code: scorecard_no_fare_data · Read the fix guide · See GTFS Best Practices (opens GTFS Best Practices on an external site)
- Info147 instances
Unsorted stop times (flagged by the MobilityData validator).
See the linked rule for what this affects.
Fix: Review the rule documentation for 'unsorted_stop_times' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)
Finding code: unsorted_stop_times · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Info8 instances
About 8 stop names are written in ALL CAPS.
Mixed-case names are easier to read in apps and are read more naturally by screen readers.
Fix: Rename stops to mixed case where the language has letter case (for example, 'Central Station'). (Often a bulk fix in your scheduling software.)
Finding code: scorecard_stop_names_all_caps · Read the fix guide · See GTFS Best Practices (opens GTFS Best Practices on an external site)
- Info2 instances
The feed includes a file that is not part of the GTFS spec.
Apps ignore files they don't know, and a stray file can hide a misspelled standard file name.
Fix: Check the flagged file name for a typo of a standard GTFS file. Remove it if it is a vendor extra. (A quick look at the flagged file.)
Finding code: unknown_file · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Info1 instance
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.
Fix: Check the flagged column names for misspellings of standard GTFS fields; remove them if they are vendor extras. (A quick look at the flagged files.)
Finding code: unknown_column · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Info1 instance
feed_info.txt has no technical contact (feed_contact_email or feed_contact_url).
Trip-planning apps and regional data coordinators 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.)
Finding code: scorecard_no_feed_contact · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
NTD GTFS readiness Not ready
Resolve this before you certify on the D-10. Service data expired 1554 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 1554 days ago, so FTA would find the link out of date.
- 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 11320 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 Not yet
This feed is close to the conformance mark. Service data expired 1554 days ago.
- Valid Met
- Passes validation with no errors.
- Current Not yet
- Service data expired 1554 days ago.
- Accessible Met
- States wheelchair access on 90% 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.
- 23 of 135 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.
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.
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.
A local transit-data support resource is Michigan Public Transit Open Data Program. MDOT's program helping agencies produce and maintain GTFS and GTFS-Flex. This resource supports agencies; it is not a scoring authority.
- Correctness 58 / 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 0 / 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 74 / 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.
