耦合功能连接性的TOD发展模式“节点—场所”测度模型构建

More than"Node—Place":Construction of Innovative TOD Measurement Model Coupling Functional Connectivity

以交通为导向的发展是一种有效地将土地利用与交通相结合的规划模式。通过改进传统的“节点—场所模型”,增加了描述两者之间“关系”的维度。首先,基于模糊层次分析法确定评价体系中各指标的权重,从而评价不同站点之间的差异。其次,用自组织映射聚类依据3个维度的综合得分将轨道交通站点划分为四类。最后,在上述分析的基础上,给出针对当前轨道交通的改进措施。

Transport-Oriented Development(TOD)is a planning model that combines land use and transportation.The article improves the traditional"node-place"model and increases the"tie"which describes the node-place relationships to establish the evaluation system.Firstly,the weight of each index is determined by FHAP(Fuzzy Hierarchical Analytical Process),by which the differences between subway stations can be distinguished.Then,SOM(Self-Organized Map)is used to classify subway stations into four categories.Finally,suggestions are given to improvecurrent rail transit system of Guangzhou.
