This paper describes a simulation model for assessing accident risk at a t-junction and its use within a large continuing project. The model is based on the concept of traffic conflicts. It is implemented by an event-stepping simulation program in which the movements of individual vehicles are monitored. The events and vehicle interactions are defined, and it is shown how drivers' turning decisions lead to the occurrence of conflicts. Preliminary results from the model are presented, indicating that its general design is correct and that it identifies areas to which effort might be directed in future. It is noted that the level of risk which drivers take at t-junctions can be modified by police activity. Finally, some comments are made on the usefulness of this kind of study within a larger project.(a) /TRRL/
