In many cities new planning concepts and reconstruction have been carried out by the authorities. This has resulted in large reductions of vehicle speed and hence in improvement of the road safety situation in these areas. However, on a national scale, the problem is so considerable that a total reconstruction of a really large number of residential streets would be necessary but is not possible in the near future. Therefore simple physical countermeasures are studied. 30 km/h speed limits and increased enforcement of the speed limits resulted in a speed reduction over a short time period, but 30-60% drove faster than the actual speed limit. Therefore other countermeasures had to be introduced. Studies were carried out with speed humps. For the covering abstract of the conference see IRRD abstract no 264967.
