Abstract

Abstract: In consideration of rainfall and over-speeding, the risk of passenger car moving on curved sections was analyzed synthetically. The simulation model of the dynamic characteristic of passenger car was established using Carsim, the critical adhesion coefficient was used as the evaluation index of passenger car moving risk, and the evaluation model of passenger car moving on curved sections was established using Matlab. The results show that under the situation of design speed 80km/h, when driving speed exceeds 96km/h, the risk probability of passenger car moving on rainfall curved sections exceeds 48.40%; when the rainfall intensity is bigger than 1.5mm/min, the risk probability of passenger car over-speeding moving on curved sections exceeds 16.35%; under the situation of rainfall and over-speeding, the risk probability of passenger car moving on curved sections which radius is 250m is 100%.
