| 摘 要： | 为提高整个航道系统的通过能力,避免航道资源闲置浪费,在NaSch模型的基础上制定船舶追越和对遇规则,建立可变道的双向航道船舶交通流元胞自动机模型。通过模拟允许变道和禁止变道两种情况下的船舶交通流,得出船舶流量、平均航速与船舶到达率的关系。研究发现,允许变道可以在不影响交通秩序的前提下有效增加整个航道系统的船舶流量和平均航速:当航道船舶交通流较为密集时,允许变道可以明显增加船舶流量;当航道船舶交通流较为稀疏时,允许变道可以明显增加平均航速。

| Abstract: | In order to improve the passage capacity of the whole waterway system and avoid waste of waterway resources, the ship overtaking and encounter rules are formulated based on NaSch model, and the cellular automaton model of ship traffic flow in variable two way waterway is established. By simulating the ship traffic flow under the conditions of allowing and prohibiting changing lane, the relationship between ship flow, average speed of ships and ship arrival rate is obtained. It is found that allowing changing lane can effectively increase the ship flow and average speed of the whole waterway system under the premise of no impact on the traffic order: when waterway ship traffic flow is dense, allowing changing lane can make the ship flow increase obviously; when waterway ship traffic flow is sparse, allowing changing lane can make the average speed of ships increase obviously. |
