First scorecard for this agency
Catalogued in Corse, 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
Populate trip_headsign to match the published sailing destination.Likely your export tool
1069 of 1069 trips have no headsign. Riders at the terminal can't tell which destination a sailing serves.

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
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.

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 191 days.
- Published accessibility data
- Accessibility information is stated for 100% of terminals and 100% of trips. This measures published data, not whether terminals or vessels 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.

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
- 4 routes · 1,069 trips
- Terminal structure
- 10 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 (10 of 10). Unstated values remain unknown. 100% of ferry trips publish a value; 100% of all ferry trips explicitly say allowed (1,069 of 1,069). Unstated values remain unknown. This reports published values, not verified physical usability.
- Bicycles
- 100% of ferry trips publish a value; 100% of all ferry trips explicitly say allowed (1,069 of 1,069). Unstated values remain unknown.
- Cars
- 100% of ferry trips publish a value; 100% of all ferry trips explicitly say allowed (1,069 of 1,069). Unstated values remain unknown.
- Fares
- Whole feed: no applied fare data is published. This is not evidence that ferry service is free.
- 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.

- Warning1069 instances
1069 of 1069 trips have no headsign.
Riders at the terminal can't tell which destination a sailing serves.
Fix: Populate trip_headsign to match the published sailing destination. (Usually a bulk edit in your scheduling software.)
Validator rule: scorecard_missing_headsigns · Read the fix guide · See GTFS Best Practices (opens GTFS Best Practices 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
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.)
Validator rule: mixed_case_recommended_field · 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.)

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 (opens GTFS Best Practices on an external site)
- Info8 instances
About 8 stop names are written in ALL CAPS.
Mixed-case names are easier to read in apps and are read more naturally by screen readers.
Fix: Rename stops to mixed case where the language has letter case (for example, 'Central Station'). (Often a bulk fix in your scheduling software.)
Validator rule: scorecard_stop_names_all_caps · 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.)

Conformance mark Awarded
This feed earns the conformance mark: valid, current, and stating wheelchair access on nearly every terminal and trip.
- Valid Met
- Passes validation with no errors.
- Current Met
- Service data covers the next 191 days.
- Accessible Met
- States wheelchair access on 100% of terminals and 100% of trips.
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 191 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 92 / 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 50 / 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.
