摘　　要：为了方便人们在城市中乘坐公共汽车,了解乘车路线方案、查询最短乘车路径和各转换站点的情况,针对城市公交WebGIS需求方面的特点,设计构建了基于WEBGIS的B/S三层结构城市公交系统的框架模型及结构体系,完成了系统空间数据库的物理、逻辑设计及相关空间数据库的组织管理,进行了相关功能模块的划分与开发。并以焦作市城市公交系统为例,介绍了乘车路线方案查询模块开发、最短路径查询模块开发和页面信息安全保障的相关技术和实现效果。这对其他城市类似系统的研发具有一定的指导意义。In order to facilitate people to take public bus in a city, to understand the route schemes, to inquire the shortest path and relevant shift stops, by connecting with the feature of requirements of WebGIS, fistly, this paper puts forward a design of framework model and its structure system for urban public transportation WebGIS based on tri-layer Browse/Server structure with MapXtreme. Secondly, the logical and physical design of spatial database of the system are finished, and organization and management of the relevant database are realized. Thirdly, the corresponding function modules are developed. Finally, taking the urban public transportation WebGIS of Jiaozuo City as an example, the paper introduces relevant techniques and effects of the programs about inquiries on path schemes and the shortest route, as well as information safeguard. The development of the system can provide guidance for similar projects.
