为了更精确地模拟内河船舶交通流的运行状态,根据内河船舶相互影响特性,将航道作为交通流中为船舶提供通航服务的主要资源,将船舶行为及相互之间的耦合关系模型化,在此基础上构建基于通航服务资源的内河船舶交通流模型。利用仿真软件进行仿真实验,结合长江干线某断面流量数据进行实例验证。实验结果表明,该模型能较好地模拟内河宏观交通流。
A navigation service resource-based inland ship traffic model is constructed for better simulation of the traffic flow. Behavior of the ships and the coupling relations between actions of ships are studied and modeled with the navigation channel resource constraints. The model is verified through simulating the traffic flow at a specific river section by using Arena software. Simulation results show that the model works well to simulate inland macro- scopic traffic flow.
