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 74 minutes ago; last changed 30 days ago.

Measured 3 of 4 score categories from the agency's own feed.

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.

Top things to fix

Fix 01

Set wheelchair_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.Likely your team

510 of 511 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.

⏱ A column in stops.txt; your scheduling software likely has it.worth about +25 points in its category

Fix 02

Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip.Likely your export tool

10335 of 10335 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.

⏱ A default or per-trip field in your export.worth about +15 points in its category

Fix 03

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

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 238 days.
Published accessibility data
Accessibility information is stated for 0.2% 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.

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.

Score by category

Correctness83.5 / 100

The MobilityData validator flagged 4 kinds of issue across 2244 instances (0 error, 2239 warning, 5 informational).

Freshness100.0 / 100

Service data covers the next 238 days.

Rider experience37.0 / 100

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.

Accessibility0.1 / 100

0% of stops state accessibility (0% marked accessible). Reflects what the feed states, not verified physical usability.

2 accessibility depth signals

  • 1 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (55).

    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.

  • 269 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("Catoctin Cir & Edwards Ferry Rd", "Catoctin Cir & First Citizens Bank", "King St & Davis Ave", 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.

Everything we checked

8 findings, ordered by severity.

Show every finding
  • Warning10335 instances

    10335 of 10335 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.)

    Finding code: scorecard_wheelchair_accessible_unknown · Read the fix guide · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)

  • Warning2236 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)

  • Warning510 instances

    510 of 511 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)

  • Warning2 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)

  • 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

    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)

  • Info5 instances

    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.

    Fix: Check whether the gap is real, like a seasonal break; if not, add the missing dates to the calendar. (A review of your calendar dates.)

    Finding code: big_gap_in_service · 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 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 238 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 10335 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. 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 Met
Service data covers the next 238 days.
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.

Clears the Google and Apple Maps four-week coverage bar. This feed has 238 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.

Correctness 84 / 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 37 / 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.

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/loudoun-county-transit/2026-08-01.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 2026-08-01. 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.
