摘要
城市交通网络是城市空间形态的基本骨架,交通网络的定量研究是对城市空间形态可控参数研究的重要方面.在GIS平台上利用拓扑分析可确定交通网络的整体层次结构及复杂程度,并可进一步分析交通网络的基本形态;长度维数主要描述网络密度的变化情况;而分枝维数主要描述网络内部的复杂程度及其连通情况.利用扩展维数分析城市交通网络有利于了解交通网络的动态变化过程.
City traffic network is basic framework of urban spatial form, ration researching traffic network is important aspect of controllable parameter of urban spatial form. Whole hierarchy and complexity of traffic network can be decided by using topology analysis on GIS software, and the basic form of urban traffic network can be analyzed further; lengthradius dimension can describe the changes of network density; and ramificationradius dimension can describes the complexity and accessibility of urban network. It is propitious to understand dynamic changing process of traffic network using expanding dimension ration analyze urban traffic network, topology analysis,lengthradius dimension and ramificationradius dimension could be regard as reference factors of ration in describing urban traffic network.
