| Abstract: | That the traffic sign is ensured to be discerned and cognized exactly by drivers is a chiefly problem in traffic sign setting. On the basis of research on visibility distance of traffic sign carried out by large numbers of driving experiments, the impact of light on traffic sign visual angle threshold in different driving speeds is discussed, then their quantitive relationships are given. |
