The development of a model for simulating traffic conflicts started at the technical research centre of Finland in 1973. The model was first completed in 1974, but it has been improved continuously. The input information needed by the model consists of the geometry of the road environment, the amount of traffic, the speed distribution of different vehicle flows and the phasing scheme of the possible signal control. The output of the model consists of the number of conflicts in the time given classified by the severity and the type of the conflict in different parts of the road environment studied. The advantages and disadvantages of the method are listed. For the covering abstract of the conference see IRRD abstract no 265671.
