通过构建虚拟节点和换乘线路，将包括车联网、公交线网和轨道交通线网在内的复杂交通系统转化为超级网络，建立了复合超级网络交通系统通行能力评价模型，上层模型为最大流问题，反映了复合交通系统的最大服务流；以芜湖市交通网络系统容量计算为例，计算结果表明网络容量与城市南向东向发展战略吻合较好，验证了模型和算法的正确性和有效性。
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.
