摘要: 为研究海港进出港航道的通过能力,探究航道服务水平,采用元胞自动机理论对海港进出港主航道进行离散化建模,对船舶在航道中的运动规则采用分段处理,重点考虑弯曲航段存在交通“警惕区”,分别对顺直航段和弯曲航段的船舶运动规则进行条件约束,通过仿真实验得到航道的船舶流量和航道的最大船舶通过能力,计算出航道的饱和度并对航道服务水平进行评价。仿真实验结果验证了模型能够较为准确地反映航道船舶运行情况,并对目前和远期的航道服务水平进行了评价。

Abstract: In order to study the passage capacity of the seaport and explore the service level of the channel, the cellular automata theory is used to discretize and model the main channel of the seaport, and the movement rules of the cell in the channel are processed in sections. In addition, this study focuses on the existence of a traffic "warning zone" in the curved channel section. The ship motion rules of the straight channel section and the curved channel section are respectively constrained, through simulation experiments, the vessel traffic flow of the channel and the maximum ship passing capacity of the channel are obtained, the saturation of the channel is calculated and the service level of the channel is evaluated. The simulation results show that the model can accurately reflect the ship operation in the channel and evaluate the current and long-term service level of the channel.

Key words: waterway engineering, channel passing capacity, cellular automata, service Level, segment constraint
