摘　　要：为了解决城市步行网络规划缺少定量数据支撑的问题,提出利用兴趣点(Point of Interest,POI)数据计算路段潜在步行需求强度,进行步行网络规划.以南京新街口地区为例,从开放地图平台获取POI数据和路网数据,采用Floyd最短路算法筛选潜在步行出行起讫点对和出行路径,计算路段潜在步行需求强度,进行步行网络等级划分,并提出步行空间改善对策建议和步行环境提升设计指引.与传统规划方法相比,论文方法将步行需求细化到了具体路段,在步行路网分级依据上更明确,并能充分考虑到支路和街巷的步行需求.研究结果对城市步行网络规划具有一定的指导意义.In order to solve the problem of lack of quantitative data support in urban pedestrian network planning,this paper proposes to use the Point of Interest(POI)data to calculate the potential walking demand intensity of road sections for pedestrian network planning.Taking the Xinjiekou District of Nanjing as an example,the POI data and road network data are obtained from the open map platform,and the Floyd shortest path algorithm is adopted to screen the potential walking trip origin-destination pairs and travel routes,then the intensity of potential walking demand on road sections is calculated,and the walking network is classified.Suggestions for improving walking space and guidelines for improving walking environment are put forward.Compared with the traditional planning method,the walking demand is refined to specific sections,which is more clear in the classification basis of the walking network,and can fully consider the walking demand of branch roads and streets.The research results have certain guiding significance for urban pedestrian network planning.

关 键 词：步行网络 POI数据 步行权重 潜在步行需求强度 步行空间改善
