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.

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 20 days.
- Published accessibility data
- Accessibility information is stated for 0% of stops and 0% 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 2 kinds of issue across 2 instances (0 error, 2 warning, 0 informational).
Service data runs out in 20 day(s). Publish an updated feed soon or riders will lose trip planning.
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 not published.
0% of stops state accessibility (0% marked accessible). Reflects what the feed states, not verified physical usability.
3 accessibility depth signals
3 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (31, 42, 51).
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.
47 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("Dental on Elliott Dr", "Newton Rd - MERF", "Hancher/Park Rd", 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.
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.

- Warning929 instances
929 of 929 trips don't say whether the vehicle is wheelchair accessible.
Even with accessible stops, riders need to know the bus itself can take them.
Fix: Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip. (A default or per-trip field in your export.)

95 of 95 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.)

- Warning1 instance
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)
- Warning1 instance
This feed's service calendar runs out within the next 30 days.
If a new feed isn't published before it ends, trip planners will drop your agency and riders will see no service.
Fix: Schedule a feed re-export now so the new calendar is live well before the current one ends. (Usually a re-export from your scheduling software.)
Finding code: feed_expiration_date30_days · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
Service data runs out in 20 day(s).
When the calendar runs out, trip planners stop showing this agency. Fixing it now is calmer than after riders notice.
Fix: Re-export with a validity window that reaches at least 60 days out. (One export setting.)
Finding code: scorecard_feed_expiring_soon · Read the fix guide · See GTFS Best Practices (opens GTFS Best Practices 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)
- Warning1 instance
This feed models stations or entrances but has no pathways.txt.
Trip planners can't guide riders through the station, and there is no step-free route information for wheelchair users.
Fix: Add pathways.txt connecting entrances, platforms, and any elevators, with a level for each. (Worth it for multi-level or large stations; flat stops don't need it.)

NTD GTFS readiness Needs attention
This feed is close to NTD-ready. Service data runs out in 20 days; renew before you certify.
- Published Ready
- Published at a public URL.
- Valid Ready
- Passes validation with no errors.
- Current Needs attention
- Service data runs out in 20 days; renew before you certify.
- 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 929 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 runs out in 20 days; renew to qualify. States wheelchair access on 0% of stops and 0% of trips; the mark needs 90% of each.
- Valid Met
- Passes validation with no errors.
- Current Not yet
- Service data runs out in 20 days; renew to qualify.
- 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.
At risk for the Google and Apple Maps four-week coverage bar. This feed has 20 days of service left. Maps needs at least four weeks (28 days) of upcoming service, so your agency will fall out of trip planners soon. Re-export with a longer calendar.
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.
- Correctness 92 / 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 33 / 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 45 / 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.
