高速公路标志牌偏转角优化设计研究

摘要

针对长湘高速双向六车道标志牌的遮挡问题,根据光的逆反射性能及驾驶员对标志的视认性,通过计算不同偏转角度下入射角的大小对反射角的影响关系,得出了标志牌的最佳偏转角度.%In order to resolve the traffic signs being blocked problems in Changxiang Expressway which with six lanes in bothway, according to the retroreflection properties and the depending on the recognition of signes for drivers, and calculate the incident Angle values under different deflection Angle to the reflection Angle influence, then obtain the best deflection Angle of signs for Changxiang Expressway .
