| 摘 要： | 眩光是影响高速公路夜间行车交通安全的重要因素。为了对不同线形路段上的防眩板高度进行合理的设置，本文分析了不同线形条件与防眩板高度的关系，考虑路线线形、车道组合、中央分隔带宽度等参数，建立了平面线形和凹形竖曲线的防眩板高度计算模型，得出了不同竖曲线半经及坡度差条件下的防眩板高度变化范围。最后结合理论及数据，对实际工程进行了分析，计算出了不同线形路段上防眩板高度的实际需求。

| Abstract: | Glare is an important factor affecting the traffic safety of the expressway at night. In order to set the height of the anti-glare plate on different linear sections, the relationship between different linear conditions and height of anti-glare plate is analyzed. The parameters such as the line shape, the combination of lane and medial divider width are considered. The anti-glare plate height calculation models of plane linear curve and concave vertical curve are established, and the range of anti-glare plate height in the different linear conditions and the difference of slope is obtained. Finally, based on the theory and data, the actual project is analyzed. The actual demand of anti-glare plate height on different linear sections of expressway is calculated. |
