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.

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. Review the rule documentation for 'missing_required_file' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

    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 is in 73 days.
Published accessibility data
Accessibility information is stated for 0% 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

Correctness60.0 / 100

The MobilityData validator flagged 4 kinds of issue across 8 instances (7 error, 1 warning, 0 informational).

Freshness85.0 / 100

Service data covers the next 73 days.

Rider experience52.3 / 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.

Accessibility37.5 / 100

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

1 accessibility depth signal

  • 1 stop name(s) use abbreviations or symbols a screen reader may mispronounce, with no spoken form set ("St Jean de Monts").

    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.

Over time

This is the first scorecard for this agency. A trend and a "what changed" summary appear here once it has been checked more than once.

Everything we checked

8 findings, ordered by severity.

Show every finding
  • Error5 instances

    Missing required file (flagged by the MobilityData validator).

    See the linked rule for what this affects.

    Fix: Review the rule documentation for 'missing_required_file' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

    Validator rule: missing_required_file · See MobilityData GTFS Validator rules

  • Error1 instance

    Invalid input files in subfolder (flagged by the MobilityData validator).

    See the linked rule for what this affects.

    Fix: Review the rule documentation for 'invalid_input_files_in_subfolder' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

    Validator rule: invalid_input_files_in_subfolder · See MobilityData GTFS Validator rules

  • Error1 instance

    Missing calendar and calendar date files (flagged by the MobilityData validator).

    See the linked rule for what this affects.

    Fix: Review the rule documentation for 'missing_calendar_and_calendar_date_files' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)

    Validator rule: missing_calendar_and_calendar_date_files · See MobilityData GTFS Validator rules

  • Warning81 instances

    81 of 81 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.)

    Validator rule: scorecard_wheelchair_boarding_unknown · Read the fix guide · See GTFS Schedule reference

  • 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.)

    Validator rule: missing_recommended_file · Read the fix guide · See MobilityData GTFS Validator rules

  • 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.)

    Validator rule: scorecard_missing_feed_info_dates · Read the fix guide · See MobilityData GTFS Validator rules

  • 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.)

    Validator rule: scorecard_no_fare_data · Read the fix guide · See GTFS Best Practices

  • 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.)

    Validator rule: scorecard_no_feed_contact · Read the fix guide · See MobilityData GTFS Validator rules

Conformance mark Not yet

This feed is close to the conformance mark. 3 validator errors to resolve. States wheelchair access on 0% of stops and 100% of trips; the mark needs 90% of each.

Valid Not yet
3 validator errors to resolve.
Current Met
Service data covers the next 73 days.
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.

Clears the Google and Apple Maps four-week coverage bar. This feed has 73 days of service ahead, clearing the four-week (28-day) window Maps asks for. The feed also carries 7 validator errors, the other thing Maps checks at onboarding; the findings below name each fix.

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. Read the full standards crosswalk.

Correctness 60 / 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.
Freshness 85 / 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.
Rider experience 52 / 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/yole-challans/2026-07-19.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 2026-07-19. 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.
