中文摘要：
提出了基于J2EE技术的城市交通诱导Web．GIS三层模型系统实现方案．并以北京市为例，采用Struts＋Hibemate＋JDBC技术构建了B／S结构的实时交通信息发布与诱导系统，克服了已有的城市交通信息Web-GIS系统只面向交通管理层的局限．该Web-GIS采用MapXtreme Java作为地图管理构建的瘦客户机，服务器模式，通过将查询道路与GPS实时浮动车数据进行动态匹配，来获得路线实时的交通信息，并结合重要的道路消息，为出行者提供可靠参考．
英文摘要：
In this paper, a system scheme of Web-GIS system with triplex-frame model based on J2EE is proposed. Then, taking Beijing as an example, technologies such as Struts, Hibernate and JDBC are adopted to construct a real-time B/S system for urban traflqc information distribution and guidance. Such a structure can overcome the limitation that the present traffic Web-GIS system is only traffic management oriented. The Web-GIS system uses MapXtreme Java Software as a GIS manager to represent a Thick Client/ Server model. In order to obtain realtime traffic information, real-time GPS data from floating vehicles on road is applied to map-matching with the GIS data of the queried road dynamically, considering some important road news. By this way, reliable guidance information can be provided to travelers.
