Accident Risk Due to Age and Year of Manufacture of the Car 700442

First, the description of a new method is given, which has been found suitable, to supply mass data of road accident exposure for the comparison of risk potentials of various driver, vehicle, and road network characteristics with each other.

The main body of the paper presents a selection of accident involvement rates of cars per 10⁸ miles of performance, obtained by the described method. The rates given, compare risk potentials of cars of various age classes and years of manufacture, used in Metropolitan Brisbane in 1961.

The effect of some driver-attributes (age and sex), the day of week of occurrence, and the power/weight ratio, on the size of the studied car-involvement rates is discussed.
