First scorecard for this agency
Catalogued in Pays-de-la-Loire, France.
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 v1.2, validator 8.0.1.
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
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
8 of 8 trips don't say whether the vehicle is wheelchair accessible. Even with accessible terminals, riders need to know the vessel itself can take them.
⏱ A default or per-trip field in your export.worth about +15 points in its category
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

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 526 days.
- Published accessibility data
- Accessibility information is stated for 100% of terminals and 0% of trips. This measures published data, not whether terminals or vessels are physically usable.
- Fare information
- Fare information is published using GTFS Fares v1.
- 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.

Ferry data profile
A ferry-specific view of what this GTFS feed publishes. Schedule measurements use ferry routes and trips only; fare and realtime facts are labelled as whole-feed. Unknown values are not treated as no.
- Ferry service
- 2 routes · 8 trips
- Terminal structure
- 4 ferry boarding locations; no parent-station hierarchy is published.
- Terminal access
- Not applicable: no ferry boarding location is linked to a parent station, so stop_access is not permitted here.
- Published accessibility
- 100% of ferry boarding locations publish a value; 100% of all ferry boarding locations explicitly say allowed (4 of 4). Unstated values remain unknown. Unknown: none of the 8 ferry trips publish wheelchair_accessible. This reports published values, not verified physical usability.
- Bicycles
- Unknown: none of the 8 ferry trips publish bikes_allowed.
- Cars
- Unknown: none of the 8 ferry trips publish cars_allowed.
- Fares
- Whole feed: applied fare data is published using GTFS Fares v1.
- Realtime
- Whole feed: no GTFS-Realtime endpoints are configured in this scorecard.
Descriptive only. This profile does not change the grade or verify vessels, terminal facilities, vehicle carriage, fares, or accessibility in the real world. Field meanings follow the GTFS Schedule reference.

- Warning8 instances
Missing bike allowance (flagged by the MobilityData validator).
See the linked rule for what this affects.
Fix: Review the rule documentation for 'missing_bike_allowance' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed. (Varies.)
Validator rule: missing_bike_allowance · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning8 instances
8 of 8 trips don't say whether the vehicle is wheelchair accessible.
Even with accessible terminals, riders need to know the vessel 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.)
Validator rule: scorecard_wheelchair_accessible_unknown · Read the fix guide · See GTFS Schedule reference (opens the GTFS Schedule reference on an external site)
- Warning6 instances
Some route lines list the same point twice in a row.
Repeated points don't hurt riders, but they can skew distance math and hint at a shaky export.
Fix: Turn on shape cleanup in your export tool, or drop the repeated points from shapes.txt. (Usually one export setting.)
Validator rule: equal_shape_distance_same_coordinates · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Warning1 instance
Some files leave out fields that GTFS asks for but does not require.
Recommended fields like agency_phone or stop descriptions make the feed more useful to riders and trip planners.
Fix: Review the flagged fields and fill in the ones your riders would use. (A field at a time; not urgent.)
Validator rule: missing_recommended_field · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules 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.)
Validator rule: missing_recommended_file · 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.)
Validator rule: scorecard_missing_feed_info_dates · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
- Info6 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.)
Validator rule: 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.)
Validator rule: scorecard_no_feed_contact · Read the fix guide · See MobilityData GTFS Validator rules (opens the validator rules on an external site)
Conformance mark Not yet
This feed is close to the conformance mark. States wheelchair access on 100% of terminals and 0% of trips; the mark needs 90% of each.
- Valid Met
- Passes validation with no errors.
- Current Met
- Service data covers the next 526 days.
- Accessible Not yet
- States wheelchair access on 100% of terminals 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 terminal and trip is wheelchair accessible.
A pass credential for a feed that is valid, current, and states wheelchair access on nearly every terminal and trip. Accessibility here measures what the feed publishes, not whether a terminal is physically usable. How the conformance mark works.
Clears the Google and Apple Maps four-week coverage bar. This feed has 525 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. Read the full standards crosswalk.
- Correctness 79 / 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 78 / 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.
