Aiming at the influencing factors of driver"s hazard perception, hazard perception experiments and self-reported data collection were carried out first, k-means clustering analysis method was used to divide the hazard perception time into three categories, and ordered Logistic regression analysis method was used to test the significance of the different factors. The results show that the characteristics of the dangerous condition have an impact on the driver"s hazard perception, the more clutter the traffic condition is; the longer the time required, the more dangerous the traffic condition is, and the shorter the time required; Drivers" characteristics and experience have an effect on hazard perception time. The time of males is shorter than that of females; The richer the driving experience of motorcycles or electric bicycles, the better the hazard perception; Driving age, mileage and bicycle driving experience have no significant effect on the hazard perception time. The influence of environmental factors and demographic factors on driver"s hazard perception is multifaceted.
