unchanged since 2026-07-08
Ahead of 8% of all tracked agencies and 8% of mid-size agencies. Operates in Maryland.
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 8 hours ago; last fetch returned HTTP 404.
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.

Service data ended 496 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.

Stop time timepoint without times (flagged by the MobilityData validator).

Some trips have stop times whose distances along the route go backwards.
Apps can show buses jumping backwards or mis-order stops.

Service data ended 496 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).

383 of 383 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.)

Some stops sit far from the route line they belong to.
Trip planners may draw the bus route through the wrong streets or point riders to the wrong corner.

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.

2 of 824 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 (most small-agency fleets are 100% accessible, so this is often a single default). (Often one default setting in your export.)

When the calendar ends, Google Maps and other trip planners drop your agency entirely. Riders see no service at all.

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.

Beyond the grade
Opportunities that do not change your grade today: fare detail, on-demand service, and deeper accessibility data.
5 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (40, 60, 61, Emmitsburg Thurmont Shuttle, East Frederick Shuttle).
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.
22 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("Spectrum Drive at M&T", "Industry Lane @ North American Housing", "Route 355/South Market Street at Noland", and more).
Consider: Add tts_stop_name with the spoken form, e.g. 'Main Street and Second Avenue', for the affected stops.
Some fixes we can make for you
These are the safe mechanical fixes, applied to a copy of your feed. They change only what is certain and leave everything else untouched. Review the diff before you publish.

NTD certification readiness Not ready
Resolve this before you certify on the D-10. 2 validator errors to resolve. Service data expired 496 days ago, so FTA would find the link out of date.
- Published Ready
- Published at a public URL.
- Valid Needs attention
- 2 validator errors to resolve.
- Current Not ready
- Service data expired 496 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.
- shapes.txt covers your trips Ready
- All 824 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 Not yet
This feed is close to the conformance mark. 2 validator errors to resolve. Service data expired 496 days ago. States wheelchair access on 0% of stops and 100% of trips; the mark needs 90% of each.
- Valid Not yet
- 2 validator errors to resolve.
- Current Not yet
- Service data expired 496 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.
Can riders use it?
Checks beyond structural validation: places where the feed is valid but a rider still could not travel.
- 3 of 383 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. The feed also carries 148 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.
- Correctness 25 / 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 75 / 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.

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/frederick-county-transit/2026-07-09.json and never overwritten, pinning the grade, category scores, rubric version, validator version, and the scored feed's sha256 as they stood on 2026-07-09. Use it in a board packet, an NTD narrative, or a research citation instead of linking the live page, whose content will differ on your next visit.
