Traffic management systems for ships are playing an increasingly important role in major ports throughout the world. The function and performance characteristics of these systems are influenced by the physical geometry of the ports and by the dynamics of the port traffic. In a given traffic system intersections between ship routes lead to a potential need for operator intervention to resolve conflicts and promote an orderly and safe flow of traffic. The results in this paper are related to the problem of determining the relative difficulty associated with managing high-density route intersections and for suggesting route structures or regulatory improvements when such flexibility is allowed. The model can be used to distinguish between traffic situations due to high traffic densities and those due to the occurrence of a statistically unusual event. A model is developed for conflicts between ships at route intersections. Quantitative measures are presented for conflict intensity and duration and for intersection capacity. These measures are shown to be related to the geometry of the intersection and to the statistics of the incident flows. An optimum intersection angle is found.
