基于组件式GIS的交通诱导和拥堵预警系统开发

提出了基于组件式GIS开发交通诱导和拥堵预警系统的设计思想与实现方法,采用面向对象的可视化编程技术VC,将地图控件MapX嵌入其中,实现了电子地图的常规功能、交通信息维护、路径诱导及拥堵预警等功能.为验证系统性能,以重庆市渝中半岛电子地图为例进行仿真实验,结果表明,该方法可以高效地开发地理信息系统,系统的各项功能可得以比较好地实现,对城市交通管理起到辅助决策的作用.

Development of Traffic Guidance and Congestion Warning System Based on Components GIS

Based on components GIS,the design and implementing method of a traffic guidance and congestion warning system is presented in this paper.The object-oriented visual programming technology is applied and the control MapX is embedded in VC.The system enjoys the functions such as the conventional functions of the electronic maps,traffic information maintenance,route guidance and congestion warning.To validate the performance of this system,simulation is carried out in the traffic network of Yuzhong peninsula in Chongqing.The result shows that this method is efficient in developing the geographic information systems,which plays an important role in decision-making support of urban traffic management.
