城市可步行空间数据建库与应用研究

Construction of Urban-Walkable-Space-Database and its Application

步行空间是城市空间中最基本的组成部分之一,是城市交通的重要通道。在倡导绿色出行、提升城市生活品质的宏观需求下,城市可步行空间的数据资源基础地位日益突显。但当前国内对城市可步行空间的数据生产、应用研究较少,导致数据资源缺乏。提出城市可步行空间的数据分类体系,并利用城市三维模型资源对城市可步行空间进行自动提取、建库和分析,为城市精细化管理和品质提升提供了数据支撑。

Walkable space is one of the fundamental components of urban system and as well an important means for urban transportation.As basic data resource,urban walkable space data starts to receive the increasing importance while we put effort on the event of Advocating Green Travel and Improving the Quality of Urban Life.But there is still a lack of data production and Application Research on urban walkable space.This paper presents a data classification scheme of urban walkable space,the automatic extraction,database construction and analysis based on 3D city models.It provides of data support for urban fine management and quality improvement on urban inhabitants life.
