根据海上交通工程方法研究了交通流的生成与发展规律以及交通网络的时空分布 ,提出了基于航路的港口航道交通流的仿真模型 ,其中船舶避碰模型采用操船者主观危险度 SJ模型 ,开发了以电子海图为背景的仿真系统 ,仿真结果与客观事实相符 . According to the method of sea traffic engineering, the law of traffic flow generation and development and the space-time distribution of traffic network are researched. The simulation model of traffic flow in port fairway based on fairway is proposed. The ship collision avoidance model adopts the SJ model of submarine risk of naval vessel, The simulation system is based on the electronic chart. The simulation results are in line with the objective facts.
