Abstract

In order to study the effect of adverse weather on driver vision in cold urban areas, Firstly, the mechanism of the effect of adverse weather conditions such as rainfall, snowfall, and fog on drivers' vision was analyzed; secondly, the effect of different vehicle speeds and illumination levels on drivers' visual adaptation time under adverse weather conditions was analyzed by extracting drivers' reaction times at different vehicle speeds and target contrast levels with different illumination levels (E); finally, regression fitting was carried out on the average driver reaction times and ambient illumination data to analyze their Finally, the mean driver reaction time and the ambient illumination data were fitted to the regression to analyze their correlation. The study shows that bad weather has a significant impact on ambient illumination, visibility, and driver vision. The incidence of bad weather leads to a sharp decrease in road visibility and illumination, and as road illumination decreases, driver reaction time increases, which is likely to cause traffic accidents.
