Réseau urbain Möbius

Grade C · 78.8 / 100

Down 1.0 points since 2026-10-15 (C to C).

For this call: lead with the grade and the three fixes below, then confirm the feed is current and the rider information is complete. Each fix is framed as a next step, not a failure.

What changed since the last check

  • Correctness no change
  • Freshness no change
  • Rider experience no change
  • Realtime quality down 5.0

No longer reported since the last check (1 finding):

  • Realtime data was up to 61 seconds old when sampled. (scorecard_rt_stale)

This compares feed state. It does not identify who made a change or why.

Top three things to fix

  1. Ask your AVL vendor to check that every vehicle assignment reaches TripUpdates. School-day and tripper runs are the ones most often left out.

    45 of 90 trips scheduled during the sampling window had no live predictions. Riders on those trips get schedule times labeled as live. Caltrans asks that every trip you run shows up in TripUpdates.

    This was measured over a realtime sampling window, so it has no feed-wide share.

    Effort: A vendor data-mapping question.

  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.

    This one is about the feed as a whole, so there is no share of it to count.

    Effort: A small file for most flat-fare systems.

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

    11257 of 12172 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the bus itself can take them.

    Fixing this covers 11,257 of 12,172 trips, about 92% of them.

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

Riders and need behind these fixes

  • Rider-trip figures come from the United States National Transit Database, which does not cover this feed's country.
  • The served-area need overlays cover the United States and Canada, so none of them applies to this feed.

These describe this feed only. They do not rank agencies, and they do not change the grade or the order of the fixes.
