Abstract
Total revealing power is one of the criterion of visibility of road lighting,and it defines the sum of therevealing power of silhouette vision and reverse silhouette one. We found out that revealing power of obstacles which has 20% reflection dropped on the motoway is 65% by the research in 2002- 2003,and there are comparatively muchhigher reflection than Smith's study.As a result,it is important to keep road surface luminance to satisfy the required visibility,and vertical illuminance can be either higher or lower,depending on the purpose something like making preceding cars more clearly.
