城市群城际客运通道结构设计研究

A Research on Intercity Passenger Transport Corridor Structure Design of Urban Agglomeration

城市群城际客运通道为区域内经济活动组织提供空间载体,引导城市群空间结构合理演化,城市群城际客运通道结构设计也即确定通道运输方式的合理构成,应同时兼顾供给者、需求者的诉求,实现供需动态平衡。在阐述城市群城际客运通道结构设计思路的基础上,从供需主体在通道结构设计中的影响及主要目标出发,构建双层优化模型研究城市群城际客运通道合理的方式构成,引入通道饱和熵指标设计求解流程,最后通过实例分析进行验证。结果表明,该方法的适用性较强,可以为城市群城际客运通道规划提供一定参考。

Intercity passenger transport corridor provides space support for the organization of economic activities in the region, and guides the rational evolution of space structure of urban agglomeration. The structural design of corridor in urban agglomeration is to determine the reasonable composition of the corridor transport mode, and to achieve the dynamic equilibrium of supply and demand, of which both suppliers and demanders is taken into account. On the basis of explaining the design idea of inter-city passenger transport corridor structure in urban agglomeration, starting from the influence of the main body of supply and demand in the design of inter-city passenger transport corridor structure and the main objective, this paper constructs a bi-level optimization model to study reasonable structure of intercity passenger transport corridor of urban agglomeration, and then introduces the corridor saturation entropy index to design solving process. Finally, the proposed model and algorithm are verified through an application case, and they provide reference for intercity passenger transport corridor planning of urban agglomeration.
