Abstract：Urban overpass often use high mast lamp to deal with night traffic problems.Its multi-level structures allow multi-direction traffic, so it is important to ease urban traffic pressure.But domestic and foreign still lacks of research on disability glare of overpass lighting.This article put forward the evaluation index of disability glare of overpass lighting on domestic, which is significant for safe driving at night of overpass road.According to the situation that TI and GR values are generally higher than the ordinary road standard value, this paper adopts the semantic differential method based on 34 measured overpass high mast lighting scene for subjective evaluation research.The research results shown that TI and GR were highly correlated with subjective evaluation of disability glare feeling, it is said that the increment threshold and glare rating can be used as the overpass road disability glare evaluation index.TI is more suitable to evaluate main road and overline, while GR is more suitable for the ramp of overpass.
