加速的城市化进程迫切要求加强交通网络的规划与建设,而定量研究交通网络一直是城市研究中的难点,传统GIS空间分析功能在城市交通网络研究中也显不足。该文引入空间句法理论,提出通达能力CCi与集成程度CAi两个新的变量,以安徽省芜湖市为例,将空间句法模型用于城市交通网络的定量化实证研究。结果表明,芜湖市交通网络通达能力空间分布呈环状特征,与该市经济发展、交通需求基本吻合,空间句法理论可以有效地定量研究城市交通网络以及空间形态。 更多还原

【Abstract】 Focusing on the current situation of urban planning,this paper introduces a model of space syntax.This paper advanced two concepts:connective capability (CC_i) and compositive ability (CA_i).Taking Wuhu City as example,by use of four kinds of analytic indexes:C_i,CC_i,MD_i and CA_i and based on GIS,this paper makes a comprehensive analysis and evaluation to the traffic network.It shows that there is moderate correlation between urban traffic network,urban land use and economic activity and that ...
