机场地区高铁站与机场轨道站双枢纽布局模式研究

Research on Dual-Hub Layout Mode of High Speed Railway Station and Airport Rail Station in Airport Area

随着高速铁路、城际铁路及城市轨道交通逐渐引入机场地区,临空经济区的高铁站与枢纽机场航站区的地面交通中心构成了互联互通、分工协作的空铁双枢纽模式,这类以轨道交通为主体的双枢纽可开展各类空铁联运模式,以满足多元化出行需求,研究其衔接模式及设施布局具有显著的理论指导意义和实践应用价值。研究依托于交通辐射范围特征及其叠合效应提出空铁双枢纽的理论模型,并总结论证了影响双枢纽组合类型的要素,基于国内外临空经济区高铁站与枢纽机场地面交通中心的空间组合实例凝练出空铁双枢纽的空间布局及其衔接模式,分别从交通组织、设施布局、枢纽能级等方面分析各模式的运行效用和优劣特征,以对我国空铁双枢纽模式的应用实践提供理论支撑。

With the gradual introduction of high speed railways,intercity railways,and urban rail transit into the airport area,the high speed railway station in the airport economic zone and the ground transportation center in the hub airport terminal area have formed an air-rail dual-hub model featuring interconnection and division of labor and cooperation.The dual hub with transportation as the main body can carry out various air-rail combined transportation modes to meet diversified travel needs.The study of its connection mode and facility layout has significant theoretical guiding significance and practical application value.Based on the characteristics of the traffic radiation range and its superposition effect,this paper proposed a theoretical model of the air-rail dual hub and summarized and demonstrated the factors affecting the combination type of the dual hub.Based on the example of the spatial combination of high speed railway station and ground transportation center of hub airport in airport economic zone in China and abroad,this paper condensed the spatial layout and connection mode of the air-rail dual hub.The paper also analyzed the operational utility and advantages and disadvantages of each mode from the aspects of transportation organization,facility layout,and hub energy level,so as to provide theoretical support for future air-rail dual hub mode applications in China.
