摘　　要：针对进出口航道中经常出现的水上"移动瓶颈"现象,提出一种基于AIS的元胞自动机航道移动瓶颈模型。结合算例,利用模型给出相应的船舶交通流元胞自动机时空斑图,并对影响航道通行能力的移动瓶颈长度、瓶颈移动速度、船舶到达率等交通要素进行仿真分析,从机制上给出相应的措施,提高航道通行能力,降低船舶滞留率。With the aim of studying the moving bottleneck which frequently occurs and obstructs traffic in waterways, a new kind of cellular automaton model of waterway moving bottleneck based on AIS is presented. The time- space spot diagrams of waterway moving bottleneck based on ship traffic cellular automaton model are plotted. A numerical example is forwarded to analyze the effect of bottleneck length, vessel arrival rate and bottleneck moving speed on the waterway transit capacity. Suggestions are given to increase the waterway transport capacity.
