基于空间句法轴线及线段模型的城市交通规划优化研究

RESEARCH ON OPTIMIZATION OF URBAN TRAFFIC PLANNING BASED ON SPATIAL SYNTAX AXIS AND LINE SEGMENT MODEL

城市道路网是城市社会经济活动运作的载体,其特征属性对城市路网,乃至整个城市交通效益的发挥均有影响。空间句法轴线及线段模型理论作为区别于传统定性描述的定量分析方法,通过一系列形态分析变量,可基于现状量化分析道路个体的交通特性,进而分析道路整体空间布局的合理性,并为道路小品布置提供一定的依据。本文将空间句法应用于南漳县中心城区道路规划,结合定性分析和定量解析,总结交通路网良性发展的路径,进而指导南漳县中心城区规划路网及小品布置规划。

The urban road network is the carrier to keep the operation of urban social and economic activities,whose characteristics and attributes have impacts on both urban road network and even efficiency of whole urban traffic.As the quantitative analysis approaches different from the traditional qualitative description methods,the theories of spatial syntactic axis and line segment model could use a series of morphological analysis variables to make a quantitative analysis of the traffic characteristics of individual road based on its status quo,and further the rationality of overall spatial layout of the roads,providing a certain basis for the layout of shining points in the roads.This paper applies the spatial syntax to road planning in the central districts of Nanzhang County.Combining the qualitative analysis and quantitative interpretation,it summarizes the sound development paths of traffic network,and then guides the planning of road network and layout of shining points in the central districts in Nanzhang County.
