ABSTRACT
This chapter concerns traffic accident taxonomies constructed from the viewpoint of the individual, that is in relation to the accident-causing behaviour of drivers, which is a psychological typology. One of the very few traffic accident taxonomies in existence with an individual differences slant seems to be the Accident Script Analysis approach by West. Single accidents, that is, those not involving any other road user other than the driver of one vehicle, would seem to be a good candidate for a categorizer that could yield different results as compared to 'All accidents'. In classical accident proneness theory, no difference between minor and major incidents would seem to have been made, indicating that they were considered to be similar, and therefore correlated within individuals. Some of the difficulties in using categorizing in accident research would seem to stem from the lack of basic thinking about the causes of accidents in relation to the variable under scrutiny.
