摘　　要：研究凹形竖曲线路段存在的对向车辆灯光引起的眩目问题,提出遮光防眩设施的设置高度优化方案。基于工效学原理,分析驾驶人在坡道路段被对向车辆灯光影响下的驾驶行为,分析其对行车安全的影响;根据道路几何参数和空间位置,提出遮光防眩设施设置高度优化方案。研究表明,凹形竖曲线路段由于遮光设施高度不足,容易造成对向车辆灯光穿越而引发眩目,进而影响行车安全。统一高度的遮光防眩设施在坡道路段无法实现遮光目的,需要根据道路线形优化设置,避免统一高度而造成的夜间行车眩目。The problem of blinding light from opposite vehicle on concave vertical curve section is studied,and optimized scheme of height setting is put forward.Driver＇s behaviors under the influence of opposite vehicle lights on the gradient section are analyzed based on ergonomics principle,meanwhile,its impact on driving safety is also studied.The optimum proposal of shading anti-dazzle facility is brought forward on the basis of road geometry parameter and space position.Study shows that concave vertical curve section is easy to cause blinding due to inadequate shading facilities height,and consequently affect driving safety.Unified highly shading anti-dazzle facility in ramp section cannot attain the goal of shading,height shall be adjusted according to road alignment in order to avoid dazzling at night.
