【摘要】 通过构建虚拟节点和换乘线段,将复合交通系统转化为由小汽车网络、公交网络和轨道交通网络有机组合而成的超级网络,建立复合交通系统容量的超级网络分析评估模型.该模型上层为最大化流量问题,反映复合交通系统服务流量最大化,下层为出行分布和均衡配流的组合模型,反映出行者利用出行路径的选择,同时进行出行方式、换乘节点的选择.以芜湖市城市交通网络系统容量计算为例,结果显示网络容量与城市向东向南发展策略一致,反应了该模型和算法的正确性和有效性.更多还原

【Abstract】 Through constructing virtual node and transfer lines,the complex traffic system including car network,public transportation network and rail transit network was transferred into the super network,and the evaluation model of traffic system capacity of composite super network was built.The upper model was maximum flow problem,and reflected the maximum services flow of compound traffic system;the lower was the combination model of the trip distribution and equilibrium assignment,and reflected the bicycler using route choice,mode and transfer nodes choice simultaneously.By taking traffic network system capacity calculation in Wuhu city as an example,the results show that network capacity agrees well with the urban development strategy to south and to east,which proves the correctness and effectiveness of the model and algorithm.更多还原
