Study on Driving Legibility of Traffic Signs in Ice and Snow Environment

摘要

This paper, base on analyzing visibility under different conditions, analyzed the influence to driving visibility in ice snow environment, and studied driver's vision and psychology & physiology in the same environment through experimentation. So studying on driver's legibility effectiveness of traffic signs under the ice and snow condition and establishing the model, this is in favor of providing the theory evidence for installing traffic signs considering the effect from ice and snow in the long period of ice and snow season.
