摘要
交通标志的视认性严重影响行车安全。通过在标志牌的图案或字符上设置圆形透光孔,使得标志牌具有透光性,从而提高逆光下交通标志内容的视认性。阐述了透光道路交通标志牌的结构原理、制作步骤和适用范围,及其在南京-洛阳高速公路安徽段的试用效果。为透光道路交通标志牌大规模地应用提供参考。
The visibility of traffic sign directly affects driving safety.Light-permeable holes were setup on patterns and characters of sign so that light can permeate through sign to heighten the visibility of traffic signs.The structure principle,facture and applicability of light-permeable road traffic signs are expatiated on.In addition,effects of it application in Nanjin-Luoyang highway are analyzed.Those can be beneficial to popularize the light-permeable road traffic signs.
