城市群公路客运通道与城市交通网络衔接模式选择模型

Connection Model of Highway Passenger Transportation Corridor and Urban Transit Network in Metropolitan Area

为了解决城市群背景下公路客运通道与城市交通网络衔接模式选择问题,本文首先基于城市群中各类公路通道特点,量化城市群中城市间通道结构形式,建立城市群通道体系宏观架构模型,对城市群公路客运通道进行分类;其次,提出衔接模式选择模型,通过赋权计算综合城市基础属性指标,根据得到的城市发展规模指数对其进行分类.随后,基于城市连接通道的类别及城市属性,计算判断通道与城市交通网络衔接形式.最后,对成都平原城市群进行算例分析.研究结果表明,设计的衔接模式判断模型能够量化城市群客运通道类型与城市发展规模,有效判断城市群公路客运通道与城市衔接模式,能够为城市群公路网规划提供理论依据.

In order to integrate the highway passenger transportation corridor and urban transit network in metropolitan area, this paper firstly aims at measuring the structure of inter-city corridors based on the characteristics of highway corridors, and then establishes the macro-architecture model of transportation corridor in metropolitan area to clarify the inter-city corridors. Secondly, a connection selection model is proposed. The selection model calculates the basic attribute of cities to obtain the urban development scale index then clarifies them. Based on the aforementioned two models, connection mode of transportation corridor and urban network can be determined in a calculation way. Finally, Chengdu metropolitan area is analyzed as an example. The results show that the design connection model can not only measure the corridor type between cities and the scale of urban development but also judge the connection type between highway passenger corridors and urban transit network effectively. And it can provide a theoretical basis for highway network planning in metropolitan area.
