Abstract
The aim of this paper is to analyse the changes in exposure characteristics and in accident involvement, by comparing the data from the last two transport surveys carried out in 1981-82 and 1993-94 and police accident data for the same periods. The findings show a larger proportion of women and elderly people in the driver population. Comparison with accident data reveals a general decrease in the risk per kilometre travelled. A high level of risk is always observed for young male drivers, while the excess risk previously observed among elderly drivers has decreased substantially. (A)
