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 65 minutes 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.

Top things to fix

Fix 01

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 181 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

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

743 of 743 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 feed_info.txt with feed_start_date and feed_end_date to your export.Likely your export tool

feed_info.txt is missing its start/end dates (the file itself is absent) Apps and this scorecard can't warn anyone before the feed goes stale without stated validity dates.

⏱ Two fields, set once in export settings.worth about +15 points in its category

How to make and check these changes

Check the result on the published feed. Read the guide, make the change in your tool, and use the next comparable run to see whether the finding is still reported. Only an action or ticket record can attribute who made the change.

  1. Re-export the feed with a calendar that reaches further out, and set feed_info feed_end_date past your next service change. · Read the fix guide

    Make the change. Make this change in whatever tool produces your feed, then re-export.

    Check the result. The next scorecard run checks this finding again. If a comparable check no longer reports it, the feed's clearance log records that result. This confirms feed state, not who made the change. Self-check a feed before you publish.

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 181 days ago.
Published accessibility data
Accessibility information is stated for 99.5% 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

Correctness82.0 / 100

The MobilityData validator flagged 4 kinds of issue across 22 instances (0 error, 22 warning, 0 informational).

Freshness0.0 / 100

Service data ended 181 day(s) ago. Trip planners have likely already dropped this feed.

Rider experience62.4 / 100

99% of stops state wheelchair accessibility (99% marked accessible, 0% marked not accessible). This measures what the feed publishes, not whether a stop is physically usable. Fare data is not published.

Accessibility62.2 / 100

100% of stops state accessibility (100% marked accessible). Reflects what the feed states, not verified physical usability.

2 accessibility depth signals

  • 4 route badge(s) pair a color and text color below the WCAG 4.5:1 contrast bar (40, 41, 240, 211).

    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.

  • 83 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("3rd St. at Beamer SB", "3rd St. at Clover SB", "Woodland Community & Senior Center NB", 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

10 findings, ordered by severity.

Show every finding
  • Error1 instance

    Service data ended 181 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)

  • Warning743 instances

    743 of 743 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)

  • Warning15 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

    2 of 374 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)

  • Warning1 instance

    A file GTFS asks for (usually feed_info.txt) is missing.

    feed_info.txt tells apps who publishes the feed and when it expires; without it nobody is warned before data goes stale.

    Fix: Add feed_info.txt with publisher name, URL, language, and feed_start_date/feed_end_date. (One small file, set once in export settings.)

    Finding code: missing_recommended_file · 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

    feed_info.txt is missing its start/end dates (the file itself is absent)

    Apps and this scorecard can't warn anyone before the feed goes stale without stated validity dates.

    Fix: Add feed_info.txt with feed_start_date and feed_end_date to your export. (Two fields, set once in export settings.)

    Finding code: scorecard_missing_feed_info_dates · 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)

  • 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 181 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 181 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 743 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 181 days ago. States wheelchair access on 100% of stops and 0% of trips; the mark needs 90% of each.

Valid Met
Passes validation with no errors.
Current Not yet
Service data expired 181 days ago.
Accessible Not yet
States wheelchair access on 100% 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.

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.

In California, the published guideline is California Transit Data Guidelines. Caltrans' published quality guidelines and compliance checklist; this rubric is anchored to them.

California Minimum GTFS Guidelines checklist (3 of 6 measured items met)

The state's own Data Process Checklist, matched item by item to what this scorecard already measures. An item marked "not measured here" is real ground the checklist covers that this tool does not check; see the official checklist for the full picture.

  • Meets Publish GTFS Schedule at a stable, automatically-fetchable URL

    The published feed URL downloaded at the last check.

  • Not measured here Implement required fields: Fares v2, text-to-speech stop names, shapes.txt, wheelchair_boarding, and Pathways where applicable

    This scorecard measures wheelchair_boarding, shapes.txt coverage, fare data, and station pathways separately, below; it does not check the Fares v2 format specifically or text-to-speech stop names.

  • Not measured here Achieve a passing score in every category of the MobilityData GTFS Grading Scheme v1

    This scorecard automates a proxy for the Grading Scheme's rider-facing fields (see the standards crosswalk) rather than running the scheme itself, which grades by comparison to the real world by hand.

  • Not measured here Publish changes to the base schedule at least one week ahead of every service change

    This scorecard does not track a feed's publish history, so advance notice cannot be checked.

  • Meets Produce no critical errors in the MobilityData GTFS Validator

    Passes validation with no errors.

  • Not measured here Publish Trip Updates, Vehicle Positions, and Alerts feeds

    This scorecard checks realtime reachability and freshness overall; it does not check for all three feed types individually.

  • Not measured here Update Trip Updates and Vehicle Positions at least every 20 seconds

    This scorecard samples realtime freshness; it does not check this specific 20-second cadence.

  • Not measured here Publish information for at least 99% of vehicles in service

    This scorecard measures the share of scheduled trips represented in TripUpdates, a related but different figure than vehicle coverage.

  • Not measured here Keep 100% of trip_ids consistent between Schedule and Realtime

    This scorecard does not currently check trip_id consistency between the Schedule and Realtime feeds.

  • Not measured here Produce no critical errors in the Center for Urban Transportation Research realtime validator

    This scorecard does not run the CUTR realtime validator.

  • Not measured here Publish accessible feed links on the agency or regional partner website

    This scorecard does not check the agency's own website.

  • Not measured here Register GTFS and GTFS-Realtime feeds with transit.land and the Mobility Database

    This scorecard does not currently check aggregator registration for this section.

  • Gap Designate a technical contact in feed_info.txt's feed_contact_email

    feed_info.txt has no feed_contact_email or feed_contact_url.

  • Gap wheelchair_boarding stated on stops and trips

    States wheelchair access on 100% of stops and 0% of trips.

  • Meets shapes.txt with a shape for every trip

    All 743 trips have a shape in shapes.txt.

  • Gap Fare data published, or the service marked fare-free

    No fare data is published.

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/yolo-county-transportation-district-yolobus/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.
