摘要
建立基于GIS技术的道路交通事故信息系统,地图平台和空间数据库的建立至关重要。地图比例尺应大于1∶2000,才能满足事故定位、分析的要求。空间数据库的主要内容是交通安全评价模型,这也是系统的核心内容。空间数据库的建立经历了概念设计、逻辑设计、物理设计过程,主要突出了道路、事故信息的数据结构设计。
The map and space-database are specially important to found the urban traffic accident information system based on GIS. The map's scale that is more than 1∶2000 can satisfy the request of accidents position.The main content of space-database is the traffic safety estimate model,also is the key one. The design of space-database went through concept design,logical design and physical design.This process gave prominence to designing the road and data structure of accidents information.
