基于POI点数据的武汉汉阳区绿道线路选择

Greenway Route Selection in Hanyang District of Wuhan Based on POI Data

文章以武汉市汉阳区为例,基于城市POI点数据以及网络分析方法,结合城市现有道路,分析POI点服务范围,并依据服务范围对城市道路的建设需求进行评价;结合客观测量的视觉敏感度分析,采用双因素组合将城市道路分为高需求-高敏感绿道、高需求-低敏感绿道、低需求-高敏感绿道、低需求-低敏感绿道4种类型,在此基础上提出分类规划策略,并完成最终绿道线路选择。结合城市大数据的研究对于高密度建成环境中的绿道选线具有重要的借鉴意义。

Based on the POI point data of Hanyang District of Wuhan,this paper analyzes the POI point accessibility service area with an eye to the existing roads in the District using network analysis tools,and evaluate the demand for urban greenways based on the service area.In accordance with the visual sensitivity analysis of objective measurement,urban roads are finally divided into 4 types adopting the dual factors combination,i.e.,high-demandhigh-sensitivity greenways,high-demand-low-sensitivity greenways,low-demand-high-sensitivity greenways,and lowdemand-low-sensitivity greenways.Then,the classification planning strategy is proposed and the final greenways route selection is completed.The study with urban big data has great reference significance for greenways route selection in high-density built environment.
