Research On Adaptability Evaluation And Layout Optimization Of Transportation Corridor In Citygroup

Under the globalize economic integration background，a large traffic flow is formedattribute to political communication, commerce and trade between cities. As thebackbone of transportion, transportation corridor has a responsibility for the large portionof transportation tasks in city group.`Researching on the transport corridors in city group, it not only can help solving theproblem of supply and demand of traffic,but also avoids wasting transportation resources,ensures the smooth-going of transportation construction.Aim at this, this paper researcheson the problem of transport corridor in city group, the main research contents are asfollows:Firstly, by analyzing the study of the actuality in domestic and overseas, majorresearch meaning, contents, research methods and technical route are established.Secondly, transport corridor adaptive evaluation system is established, GP-DEAmethod is used for conducting a comprehensive evaluation in transport corridor of citygroups. Take Chang-Zhu-Tan city group for example, the validity of the evaluation modelvalidation is maked, the insufficient of transport corridor in Chang-Zhu-Tan city group isfounded.Thirdly, strating from the theory of transport corridor optimization,the bi-levelprogramming model and decision making model are used to optimize the lay out oftransport corridor in city group, PSO is used to solve the bi-level programming model.Finally, with the example of Chang-Zhu-Tan City Group transportation corride , thelayout of city group decision-making model is used.The innovation of this paper is to establish transport corridor adaptive evaluationsystem ,then the correlative model to optimize the lay out of transport corridor ischosed.This research not only provides effective decision-making method in optimize thelayout of transport corride, but also has important theoretical and practical significance.
