区域货物综合运输网络容量可靠性的研究

摘要

在剖析综合运输网络构成和城市路网容量可靠性的基础上,将影响网络容量可靠性的诸多要素分类。同时以综合货运网络描述模型为依托,采用较为成熟的网络保留容量概念,从货运网络容量的供给、需求和时间可靠性的关系出发,构建基于时间可靠性综合货运网络的容量可靠性模型,分析结果表明,随着路段行程时间可靠性的降低,容量可靠性的值也相应增加。%Based on the analysis of comprehensive transportation network constitution and the reliability of urban road networks capacity,the paper classifies several factors contributing to the network capacity reliability.The mature concept of network reserve capacity is adopted,while the description model of comprehensive transportation networks is employed.Starting with the relations between supply and demand of network capacity and time reliability,this paper builds its own capacity reliability model based on the time reliability of comprehensive transportation networks.
