The Insurance Road Safety Committee, TRK, decided in 1975 to commission a project aimed at evolving and testing methodology of in depth investigation of road accidents. The overriding aim of this project has been to investigate actual road accidents with a view to elucidating accident processes and identifying the causes of accidents, and in doing so to help improve the state of knowledge in this sector and in factual documentation underlying road safety measures of various kinds. In keeping with the problem sectors on which TRK chose to concentrate-the interaction between human beings, vehicles, the road- and traffic environment and the information intake, decisions of the road users - the main emphasis in the study was on events leading to the crash. The model chosen to describe the traffic system and to analyse data really determines the information to be collected and the form in which findings are presented. Work on the analytical method and the presentation of its background have therefore come to occupy a prominent position in the project. Altogether twenty-three investigations were carried out during four duty periods. A summary is given of data collected concerning the traffic situation and traffic environment, vehicles and road users respectively. This is followed by an analysis of the course of events. The concluding section summarizes the respects in which the methods that have been devised and tested differ from previous or contemporary accident investigations. /TRRL/
