Traffic Calming (Speed reducing) measures was first built in 1978 and hence forth integrated in the planning
The first large scale implementation of Traffic calming measures in a selected residential area was performed in 1981
Today more than 2500 Traffic calming measures including more than 1200 road-humps

Traffic-calming Measures Today and in the Future
Standardized design principles:circular hump with 1 m ramp on local roadscircular hump with 2 m ramp on arterials
Traffic safety as part of the planning process
400 000 € per year reserved for traffic-calming measures. Approx. cost 2500 € per road hump, 300 000 € for a roundabout
Road hump on local road with 1 m ramps
