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。
The accelerating process of urbanization urgently requires strengthening the planning and construction of transportation networks. However, quantitative research on transportation networks has always been a difficult point in urban research. The traditional GIS spatial analysis functions are also insufficient in the research of urban transportation networks. This paper introduces spatial syntactic theory and puts forward two new variables: accessibility capability CCi and integration degree CAi. Taking Wuhu City in Anhui Province as an example, the spatial syntax model is applied to the quantitative empirical research of urban traffic network. The results show that the spatial distribution of the accessibility of traffic network in Wuhu City has a ring-like characteristic, which basically agrees with the economic development and traffic demand in the city. The spatial syntax theory can effectively study the urban traffic network and the spatial form.
