道路交通标志逆反射性能与夜间视认性

为了规范和引导道路交通标志及其逆反射材料的使用，提高道路交通标志的夜间视认效果，对交通标志及其逆反射材料的等级、类别、结构、光度性能、色度性能以及国内外相关标准进行分析，研究交通标志的逆反射性能及与夜间视认性的关系。通过对国内交通标志及其逆反射材料的使用现状分析，认为夜间视认性与逆反射性能的关系较为复杂，应针对逆反射材料的类别、结构，以及在交通标志中的搭配使用等进行深入研究，并将研究成果用于修订现行交通标志的相关标准和规范。

Retroreflectivity and Night Visibility of Road Traffic Signs

In order to standardize and conduct use of road traffic signs and retroreflective material and enhance night visibility of traffic signs,grades,categories,structures,photometric characteristics,colorimetric characteristics and relative standards of traffic signs and retroreflective materials were analyzed to find out the relation between retroreflectivity and night visibility of traffic signs.By analyzing the use status of domestic retroreflective materials for traffic signs currently,it is considered that ...
