摘　　要：建立了基于GIS空间分析技术的城市路网可靠性评价方法模型,介绍了基于ArcEngine组件的路网空间查找、空间相交、几何网络连通等方法的详细构建过程与实现代码,并分析了最后以广州-佛山都市圈道路网络的可靠性差异.The concept of road reliability and its application in the evaluation of road networks are discussed.A model of reliability evaluation method for urban road network based on GIS spatial analysis is established.The model described in detail geometric network connectivity methods and implementation details of the code building process based on ArcEngine components such as space search,space intersect.Using the Guangzhou-Foshan road network as an example,we analyzed the reliability of the regional road network by the equal-area grid method.
