Samenvatting
The report presents the results of a study, the object of which was to perform an empirical analysis of in-depth accident case histories. Two aspects were studied: (1) to analyse events which immediately precede a crash, and (2) to derive driver behavioural requirements for accident avoidance imposed by a high-probability set of events. Particular attention was given to emergency traffic conflict situations which involve more than one road-user and require rapid and unplanned actions to avoid a collision. Subjective estimates of the probabilities of accident avoidance were developed for all feasible combinations of emergency situations and manoeuvres.
