Samenvatting
The risk per vehicle mile has decreased strongly since 1950. This development has a very steady and exponential progress. Each ten years the number of fatal accidents was divided into halves in the period 1 (50-1985. Oil the basis of the combination of the development of the mobility and the risk the SWOV has made an estimation of an increasing decline in the number of fatal accidents from 1100-1200 in the year 1990. This declining trend will be a joint result of many endeavours of road administrators, traffic safety experts and the vehicle industry.
