ANALYSES OF THE RELATIVE PROPORTIONS OF A SINGLE-AND TWO-CAR ACCIDENTS, AND OF THE PROPORTION OF OVERTURNING IN SINGLE-CAR ACCIDENTS

British accident records have been used to investigate the effects of model of car and age of driver on the relative proportions of different types of accidents (single-car overturning, single-car non-overturning and two-car). Appropriate statistical procedures have been used to separate car and driver age effects. It is concluded that car and driver age effects combine multiplicatively both in their influence on the ratio of single-to two-car accidents and in their influence on the proportion of overturning in single-car accidents. The influence of model of car on both these dependent variables was substantial and statistically significant. Accidents in urban and rural areas were analysed separately, and it was shown that the car effects found in these two circumstances were positively correlated. /TRRL/
