Calculation and Verification Methods of Collision Velocity between Vehicles and Two-Wheelers Based on the Uncertainty Theory

Abstract

To improve the accuracy of speed identification in car/automobile and two-wheeler collision accidents, the uncertainty theory was used to evaluate a collision speed model of the riders and the two-wheeler vehicles. First, a throwing distance-collision speed model of riders and two wheelers was built according to kinematic formulas, the theorem of kinetic energy, and the impulse theorem. Then, combined with the data on scene investigation of a collision accident of a car and an electric bicycle, the collision speed was calculated by the model. The optimum range of collision speed was obtained by using the uncertainty theory. Finally, the model and the evaluation method of uncertainty theory were proven to be reasonable and effective through MATLAB numerical verification, and PC-Crash simulation verification, as well as an analysis of the drive recorder.
