Research On Simulation Technology Of Marine Traffic System

Marine Traffic System is a stochastic and dynamic system, which involves in human, ships and environment Simulation technology is an important experience method of marine traffic studies.At first, this paper categorized marine traffic and marine traffic flow, which is based on a summarized analysis of domestic and abroad study. Secondly, based on the marine traffic survey, the statistic characteristic of marine traffic is discussed, the occurrence and development rule of traffic flow are researched. Thirdly, a simulation method of traffic flow based on fairway is presented in this paper. Finally, the Subject Judgement model is applied as an assessment model of ships collision avoidance, and the mean SJ value of sea areas is suggested as index of collision risk degree.At same time a relative membership model of fairway risk is established, which assess the danger degree of all fairways of the Dalian port. The evaluation results more tally with the results of simulation.
