In view of the the residual snow road driving dangerous neglected, and the frequent accidents of traffic problems, this paper studies the residual snow in the microscopic characteristics of the road, the characteristics of it coverage is used to define the residual snow pavement, build six different coverage of the residual snow pavement, design experiment measured the impact of the key factors affecting the adhesion coefficient of safety driving speed; Then the linear model and nonlinear model of residual snow coverage rate and road adhesion coefficient were fitted by the least square method. After evaluation, it was found that the curve fitting results of the exponential model were most consistent with the actual road adhesion coefficient. Finally, the induced value of safety speed on residual snow road surface is evaluated by vertical value analysis, and the adhesion coefficient and safety induced speed of residual snow coverage rate are obtained.
