摘要
为确定航道的交通阻抗,研究了船舶交通流的基本特性,分析了无船闸航道基本段与船闸的通航特点,建立了基于船舶交通流理论的交通时间阻抗计算模型,以客观的描述船舶交通出行时在不同交通流状态下的运行效益.算例计算分析表明,模型是可行、可靠的,能够根据船舶运行的基本实测数据确定任意路径的时间交通阻抗.
In order to determine traffic impedance of waterway,the property of vessel traffic flow was researched.A new traffic impedance model based on vessel traffic flow was developed and the characters of waterway with ship lock or without ship lock were analyzed,so that the model could describe the benefit of origin-destination under different states of traffic flow.The computation results of examples show that the model is feasible and credible.The model can determine traffic impedance of any path with some investigation data,which may offer theoretic basis to the assignment and planning of waterway network.
