Detecting Urban Local Areas Based on Configurational Properties of Street Network: A Case Study of Shenzhen
Keen Pan, Haofeng Wang
摘要 研究将基于城市形态认知的空间组构分析引入复杂网络的社区发现算法,以深圳市街道网络为例,对比分析了 街道的不同空间组构参数(转向距离、选择度、可达量)用于城市本地社区识别的效果,并应用消费大数据和 城市密度数据对识别结果的有效性进行检验。通过解析社区如何通过街道网络的连接关系而构成,不仅为城市 自组织提供了新的理论研究视角,同时也能够为城市规划设计实践提供技术工具支撑。
关键词 本地社区街道网络空间组构社区发现算法自组织    
Abstract:This study explores to adapt the configurational analysis of space syntax into the network science community detection algorithms. Using configurational properties (directional distance, angular choice, and reach measures) as weights, this study takes the street network of Shenzhen as an example, and applies street character weighted community detection methods for identifying local urban areas. Validation of the identified results is performed using per capita consumption price data (e.g., Dianping platform records) combined with urban density indicators. By deciphering how urban local areas are structured through street network connectivity, this research not only provides a novel theoretical perspective to approach urban self-organization but also offers technical support for urban planning and design practices.
