一、引言随着我国城市化进程的迅速推进,交通问题已成为制约我国城市发展的主要问题,影响着城市居民的生活质量。然而,近些年随着城市人口的集聚增加、城市空间尺度的不断扩大,交通设施引导城市空间有序拓展、提高土地利用集约的作用愈发明显,公共交通已成为城市发展的战略优选。一方面,公共交通系统的良好运营需要客流的保证.而客流的关键就是公共交通走廊沿线人口岗位的集聚,也就是城市交通可持续的关键之一就是沿线土地布局的配合;另一方面.公共交通系统建设资金投入量大,且作为公益性质的基础服务,在后续的运营中存在长期的运营补贴,因此交通系统的可持续建设的一个关键问题就是资金,但是从近些年一些建成轨道或者中低运量公共交通系统的城市案例来看,公共交通基础设施由于 I. INTRODUCTION With the rapid progress of urbanization in our country, the traffic problem has become the main problem restricting the development of our country’s cities and affecting the quality of life of urban residents. However, in recent years, with the increase of urban population and the continuous expansion of urban spatial scales, the transportation facilities have led to the orderly expansion of urban space and the intensified use of intensive land use. The public transportation has become a strategic optimization of urban development. On the one hand, the good operation of the public transport system needs the guarantee of passenger flow, and the key of passenger flow is the gathering of population and posts along the public traffic corridor, that is, one of the keys to the sustainable urban transport is the coordination of the land layout along the route; on the other hand, As the basic service of public welfare and long-term operation subsidy in the follow-up operation, a key issue for the sustainable development of the transportation system is the capital. However, from some projects completed in recent years or In the urban case of low-mass transit public transport system, the public transport infrastructure is due to
