摘要
通过构建车辆前照灯和驾驶人视线与防眩板板宽、间距、高度在道路横纵断面上投影的关系,分析在不同的高速公路几何设计要素下的防眩板设计参数,提出了在不同的设计速度、中央分隔带宽度、防眩板板宽、设置位置和设置方式情况下,适用于设置不同间距防眩板的平曲线半径值。结果表明：高速公路主线路段防眩板采用100cm板距、15~25cm板宽,无论板所处位置及偏转与否均可满足平直和平曲线段防眩要求。
By establishing the projection relations between vehicle headlamp, driver＇s sight and the width, interval and height of anti-glare plate in the cross and vertical section of road, and analyzing the design parameters of plate under different highway geometric design elements, the horizontal curve radius adapted to different intervals of anti-glare plateswas put forward. The results show thatwhether the plate is deflected or not and wherever its position is, the anti-glare plate with an interval of 100 cm and width of 15-25 cm can meet the requirements of anti-glare in straight or curved section of highway.
