Lane changing is the common behavior when cars are running. It will produce traffic conflict, reduce the efficiency of road system, and lead to malignant traffic accidents. Based on the analysis and evaluation of circular, cosine type, constant lane migration type and ladder lane transformation type, considering the driver behavior, vehicles control and dynamic constraints and thinking the obstacles as an infinite number of circles to idealize them, this paper establishes polynomial in horizontal and vertical directions respectively to indicate the position of vehicle, obtains the lane changing trajectory by testing whether the distance between circles meet some conditions, builds polynomial for the safe lane changing trajectory and real-time dynamic optimal distances between vehicles, and then utilize the MATLAB as the simulation tool to make experiments in various cases. Simulations and experimental results show that the method given in this paper to calculate the vehicle safety lane changing trajectory in the case of high-speed vehicle is feasible, effective and can give quickly safety lane changing distance.
