Transport en Commun (TEC), Wallonia

Grade F · 43.8 / 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_boarding to 1 (accessible) or 2 (not accessible) for every stop. A field survey can start with the busiest stops.

    31065 of 31065 stops don't say whether a wheelchair user can board there. Riders who use wheelchairs can't plan a trip when accessibility is marked 'unknown'; apps show no information at all.

    Estimated effort: A column in stops.txt; your scheduling software likely has it.

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

    143663 of 143663 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.

  3. Populate trip_headsign to match what the transit vehicle displays.

    143663 of 143663 trips have no headsign. Riders at the stop can't tell which direction a transit vehicle is going.

    Estimated effort: Usually a bulk edit in your scheduling software.
