摘　　要：极端恶劣天气和雾霾气象的经常发生,给高速公路运营安全带来极大隐患。因此,研发一套基于GPS授时的低能见度气象条件下高速公路主动发光诱导与自动防撞预警系统,可实现车辆智能引导、路形显示、车距警示、动态尾迹跟踪等功能。详细设计了智能诱导单元的硬件部分、上位机软件控制平台及控制策略,并给出了其控制流程图及软件界面图。选择团雾多发路段进行实地安装,应用效果明显,有效降低了事故发生率。Bad weather and fog haze bring a lot of hidden trouble to the safe operation of highway. Therefore,this article developed a set of highway active guiding and collision warning system in low-visibility conditions based on GPS timing,which can realize intelligent vehicle guidance,road shows,distance alarm,dynamic wake tracking,etc. In this paper,the hardware of the intelligent guiding unit,software control platform and control strategy were designed in detail. And the control flow chart and software interface were also given. The system has been installed in fog prone sections,and has reduced the incidence of the accident effectively.
