针对海上交通工程学中的密度-速度（流量）关系图“线性假设”的不严密性，利用基于 AIS的元胞自动机船舶交通流模型模拟再现船舶交通流，然后统计出船舶交通流密度-速度（流量）基本关系图，并给出其三相交通流理论的解释；模拟研究发现，船舶交通流包含自由流、同步流和拥挤流三种相态，相态之间的转换也包含自由流与同步流、同步流与堵塞流两种形式；船舶密度-速度之间并非简单的线性关系，船舶密度-流量之间也不是二次抛物线关系，而是不明确的多值关系。模拟方法和结论有助于解释一些复杂的水上交通现象。

Against the non-stringency of linear hypothsis in ship traffic density-velocity equations in marine traffic engineering ,and as per the ship cellular automata model on AIS-based ,simlation is car-ried ot to reproduce ship traffic flow of waterway in micro level .The simulation results are refined and new ship traffic density-velocity (flux ) non-linear equations are presented ;T he three-phase traffic the-ory explication is given .the simulation results show that ship traffic contains free flow ,synchronized flow and congestion flow ;and phase changes contain free 1 synchronized and synchronized 1 jam .The sim-ulation method and conclusions could help to explain some complex phenomena of marine traffic .
