A sophisticated marine traffic control system is necessary for full automatic maneuvering in harbors and restricted water areas. The current paper proposes a computer simulation methodology for the design of the marine traffic control system. To build a truthful simulation environment, the marine traffic is analyzed from the view points of both traffic management and knowledge representation and some key concepts relating to knowledge representing in marine traffic domain are introduced and they are implemented by knowledge engineering techniques. Based on the researches to date and analysis of the characteristics of marine traffic, four levels of traffic control are considered, they are (1) designation of route and regulations, (2) information service and advice, (3) speed scheduling and signal control, and (4) full motion scheduling. Modeling shipmaster's behavior in collision avoidance is a complicated problem. An object-based and rule-based representation is employed to model the marine traffic system. Objects in the domain are specified and two important relations are identified which make the representing model powerful and attractive not only for building the simulation system but also for the design of a real traffic control system. Some simulation results are finally given which demonstrate the effectiveness of introduced concepts and usefulness of the proposed representing model.
