高速公路交通标志设置角度和反光材料选择的研究

Study of Installing Angle of Traffic Sign and Selection of Reflecting Material for Expressway

该文根据国家的相关规范,结合国内外对于交通标志视认性研究的成果,通过标志的视认几何模型推导,探讨了高速公路交通标志在设计过程中如何确定安装角度,如何选择标志面上的反光材料,从而提高交通标志的视认性,确保交通安全。对交通标志的设计具有一定指导作用。

Based on the relative standards of the state,combined with the result of comprehension study of traffic sign at home and abroad and through educing the comprehensive geometric model of sign,the article approaches how to determine the installing angle in the course of designing the traffic signs of expressway and how to select the reflecting material on the sign surface so as to enhance the comprehension of the traffic signs and ensure the traffic safety,which has some indicative role in the design of traffic signs.
