交通枢纽选址与网络设计同时优化的模型与算法

Model of Simultaneously Optimizing the Transport Pivot Siting and Network Design and Its Algorithm

考虑到交通枢纽对交通网络的反作用,提出了交通枢纽选址与网络设计同时优化问题;给出了描述该问题的以规划者为领导者、以出行者为跟随者的双层决策模型,这种模型是基于交通均衡分配的;最后,探讨了求解此模型的算法,并给出了实际算例。

The counteraction of transport pivot siting to the network is discussed. The problem of simultaneously optimizing the transport pivot siting and network design is defined. To express this problem, the hierarchical decision model is developed with the planner as leader and traveler as follower and the model is based on traffic equilibrium. At last, the algorithm about the model is researched, and numerical example is presented.
