发展大城市公共交通体系化的研究

在我国城市,尤其是大城市,土地利用与交通之间存在的问题和矛盾已十分突出,高密度的城市土地开发和人口聚集使得城市交通需求与生成无论在时间上还是空间上都呈现高度集中的状态。从城市可持续发展与交通发展的目标出发,提出了实现我国大城市空间可持续发展与缓解当前大城市交通矛盾的有效策略,即建立以轨道交通为支撑的大城市公共交通体系,实施“枢纽型”的客运系统组织,进行以轨道交通为基轴的公交网络优化,循序渐进地进行公共交通体系化的发展培育,最终实现公共交通发展的升级。

Research on Systematizing Public Transportation for Metropolitan Areas

Within our cities, especially in metropolitan areas, there exist profound problems and conflicts in terms of demand and supply between land-use and transportation. The densely developed urban areas with highly concentrated population results in an increasingly growing demand of gen- erated trips at any point in time or space in our cities. From the perspec- tive of a sustainable development of urban land-use and transportation sys- tems, this paper proposes strategies that can be used to effectively achieve objectives of sustainable developments of urban spaces and to ease traffic problems within metropolitan areas. Those strategies include constructing a public transportation system with the rail-transit as its backbone, imple- menting a hub-based passenger transportation system to organize passenger flows, optimizing the public transportation network upon the basis of the rail-transit, developing a public transportation system step by step, and fi- nally, upgrading the public transportation system onto a higher stage.
