Study on Prediction Model of Friction Coefficient of Icy Road Surface

摘要

Road icing is an important factor affecting road traffic safety in winter. Friction coefficient of icy road is an important index reflecting road safety performance in winter. First, the main influencing factors of friction coefficient of icy road are analyzed. Using the simulation test box of bad weather traffic conditions to simulate the friction performance test of the road surface, the relationship between the main influencing factors and the friction coefficient of the road surface is analyzed. The prediction model of the road friction coefficient of the road surface is established. The results indicate that the road temperature is the main factor influencing the friction coefficient of the winter ice road surface, and the influence of the relative humidity of the environment on the friction coefficient of the ice road surface is not obvious.
