In order to standardize and conduct use of road traffic signs and retro-reflective material and enhance night visibility of traffic signs, grades, categories, structures, photometric characteristics, colorimetric characteristics and relative standards of traffic signs and retro-reflective materials were analyzed to find out the relation between retro-reflectivity and night visibility of traffic signs. By analyzing the use status of domestic retro-reflective materials for traffic signs currently, it is considered that the relation between night visibility and retro-reflectivity is complex. Grades, categories and structures of retro-reflective materials and their arrangement in pairs or groups should be researched deeply for amendment of relative standards and criteria of traffic signs.
