Aléop Yeu-Continent (Île d'Yeu ferry)

Grade B · 83.3 / 100

First check for this agency, so there is no trend yet.

What this grade measures

The quality of the schedule data this agency publishes for trip-planning apps: whether riders using Google Maps, Apple Maps, or Transit see current, correct, and complete information. It measures the data feed, not service quality or operations.

Progress this period

No newly cleared items this period. The score and trend above reflect where the feed stands today.

What needs attention next

Three improvements, in priority order, each sized so the board can see what it is approving:

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

    5170 of 5170 trips don't say whether the vehicle is wheelchair accessible. Even with accessible terminals, riders need to know the vessel itself can take them.

    Estimated effort: A default or per-trip field in your export.

  2. 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.

    Estimated effort: A small file for most flat-fare systems.

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

    Missing bike allowance (flagged by the MobilityData validator). See the linked rule for what this affects.

    Estimated effort: Varies.
