ATM Milano (Comune di Milano)
Grade F · 48.1 / 100
Down 0.5 points since 2026-07-31 (F to F).
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:
Re-export with a validity window that reaches at least 60 days out.
Service data runs out in 11 day(s). When the calendar runs out, trip planners stop showing this agency. Fixing it now is calmer than after riders notice.
Estimated effort: One export setting.
Set wheelchair_accessible on every trip. If every vehicle is accessible, this may be one default; otherwise use the value for each trip.
101327 of 101327 trips don't say whether the vehicle is wheelchair accessible. Even with accessible stops, riders need to know the transit vehicle itself can take them.
Estimated effort: A default or per-trip field in your export.
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.
