基于WebGIS的高速公路信息发布系统的设计与实现

The Design and Realization of Freeway Information Published System Based on WebGIS

随着国家对高速公路的大规模建设,高速公路路网越来越复杂.为了方便公众查询出行信息,开发了基于WebGIS的高速公路信息发布系统.本系统采用MapInfo公司的WebGIS平台MapXtreme,并且使用了目前较为先进的Java Applet构造方法,实现了通过电子地图将高速公路上反映道路畅通情况的可变限速标志进行网上发布、路线信息查询和公众出行信息服务、车辆行驶流水费用明细查询等功能.运行结果表明利用WebGIS技术克服了基于传统模式开发该系统的弊端,提高了系统的运行效率,增强大量空间数据和属性数据的处理能力.

With the large-scale construction on the freeway, the freeway network has become more and more complex. For the convenience of people querying the outing information, we developed the freeway Information Published System Based on WebGIS. This system adopts the Mapinfo Company＇s MapXtreme and uses the present advanced Java Applet forming methods, realized the function of display the changeable speed limit sign on the Internet which inflects the blocked situation in highway by showing electric map, realized the functions of mute information inquire and public outing information service based on WebGIS, realized the function of driving expense list based on WebGIS. The results showed that it overcame the malpractice of developing this system based on the traditional pattern, enhanced the system the operating efficiency, strengthened the massive spatial data and attribute data handling ability.
