大城市通勤空间特征下的城市交通组织模式研究

Research on Urban Traffic Organization Mode Under the Spatial Characteristics of Commuting in Big Cities

居住和就业的通勤空间匹配是反映一个城市空间结构良性发展的重要依据。城市交通的组织模式需要从客流通勤流动的角度考虑与职住空间匹配的组织协调关系。以南昌为例,利用手机信令数据分析多尺度的职住空间静态分布与动态职住特征,识别城市通勤圈与轨道、快速路等城市交通系统的耦合规律。探讨城市通勤圈空间结构与城市交通系统的内生互动关系,以引导大城市空间结构与交通系统的协调发展。

The commuting space matching of residence and employment is an important basis for reflecting the healthy development of a city's spatial structure.The organizational model of urban transportation needs to consider the organizational coordination relationship that matches the occupation and housing space from the perspective of commuting.Taking Nanchang as a case,the mobile phone signaling data is used to analyze the static distribution and dynamic characteristics of multi-scale employment space to identify the commuting circle’s coupling law with the urban backbone transportation system such as the track,expressway,etc.Exploring spatial structure of urban commuting circle’s interaction with the urban transportation system to guide the coordinated development of the spatial structure and transportation system of large cities.
