How it works
Positions
No vehicle reports its position to this map. Each one is drawn where the timetable says it should be right now, moved by the delay reported for it. So a vehicle can be somewhat ahead of or behind its marker. Vehicles without a reported delay carry a question mark and run by the timetable here.
Routes
The route between two stops is computed too: the shortest plausible way along the roads and tracks of OpenStreetMap, not the official one of the operator. Between stops close to each other it is almost always the same. Where it differs, a vehicle takes another way on the map than in reality; where none is found, it moves in a straight line.
Outside the area
Grey: only lines that stop inside the area are shown there, on a straight line between their stops.
