公路反光标志夜间可见性研究

Research on the Nighttime Visibility of Highway Retroreflective Signs

通过野外试验，研究反光标志夜间可见性，确定标志最佳反光亮度比以及驾驶者年龄与视认距离的关系，从而验证和补足了“七五”攻关项目在字高方面的研究。

Research on the nighttime visibility of highway retroreflective signs was carried out by means of the field tests.The optimum luminance contrast of signs and the relation between driver's age and the visibility distance were determined,so that the previous research on the height of Chinese characters was verified and complemented.
