| 摘 要： | 本文提出了基于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+ Hibernate+ 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。

| Abstract: | 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 traffic 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 real-time 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. |
