Study On The Optimization Of The Organization Mode Of Air-rail Intermodality In The Beijing-Tianjin-Hebei Region Under The Background Of Xiong'an New District

The air-rail intermodality is a joint transportation mode of civil aviation and rail transportation based on the airport integrated transportation hub.As one of the three world-class urban agglomerations in China,the rail transit facilities of the Beijing-Tianjin-Hebei region is relatively complete,and the civil aviation development system is relatively sound.Planing to carry out efficient air-rail intermodality and promote the interconnection and intercommunication of four major airports and rail transit facilities is of great significance for promoting the coordinated development of civil aviation in the Beijing-Tianjin-Hebei region.Firstly,the thesis systematically studies the related theories of air-rail intermodality at home and abroad.Next,the thesis researches the air-rail intermodality mode from the aspects of physical connection and transportation organization combined with a large number of cases.Then the thesis focuses on the research of the organizational mode optimization of air-rail intermodality in the Beijing-Tianjin-Hebei region.The thesis researches from two aspects: hardware facilities and transportation organization.On the one hand,based on the analysis of current situation of the air-rail hardware facilities in the Beijing-Tianjin-Hebei region,the optimization ideas are obtained by using complex network theory,Pajek software,ArcGIS software and other methods.On the other hand,the actual problem is abstracted as a mathematical model from the perspective of passenger travel and solved by the genetic algorithm,and the optimization ideas of the organization mode of air-rail intermodality are discussed.Finally,on the basis of the above research,the implementation strategy of setting up the air-rail intermodality in the Beijing-Tianjin-Hebei region under the background of Xiong'an New District is summarized and proposed.
