A Simulation Analysis of Pavement Skid Resistance Against Driving Safety on Curve Roads

In order to study impacts of pavement skid resistance against driving safety on curve roads,especially in a situation of braking,a vehicle-tire-road model by integrating parameters of analytical UA tire,vehicle body,and road pavement skid resistance is developed based on the ADAMS simulation platform.Kinematic parameters of vehicle in the model are derived on curve roads under different conditions of slippery pavement.Relationships between pavement skid resistance and kinematic parameters which indicating driving safety are studied.Simulation results show that varied pavement skid resistance can lead changes of kinematic parameters,which is the key factor causing potential traffic accidents.Lower skid resistance leads to rollover of vehicles,and slippery disparity in two sides of the road contacted with tires raises the risk of getting vehicles out of roads.This study can provide theoretical references for making measures to guarantee driving safety on curve roads.
