摘要
本文针对城市交通道路网的特点,根据现实的交通网络,对葫芦岛地区道路网络进行建立及分析。利用ArcGIS中的Geodatabase构建路网数据库,利用节点一弧段数据结构构建空间网络拓扑关系,生成点一弧矢量数据模型表示的道路网络。并实现四种网络分析功能:最佳路径分析、空间查询、追踪分析和缓冲区分析。
This paper,in relation to urban traffic characteristics of the road network,according to the reality of the transport net- work,establishes and analyses the road network of HuLuDao.Construct database of the road network using geodatabase in AreGIS, build topology in spatial network using the node-arc structure and generate the road network expressed by a point arc-vector data model. Realize four network analysis functions:the best path analysis,space enquiries,tracking analysis and the buffer zone analysis.
