基于碰撞点时间估计的车辆碰撞预警算法
Vehicular Collision Warning Algorithm Based on Time to Collision Point Estimation
摘要
Abstract
Aiming at the collision of vehicles at intersection, a vehicular collision waring algorithm based on Time to Collision Point (TTCP) estimation is proposed to decrease the probability of traffic accidents and improve the smoothness of vehicular traffic flow at the road intersection. Different scenarios are analyzed for vehicular collision at the road intersection, which is influenced by the operation of traffic lights. The formulae of the collision point coordinate and TTCP are proposed for different cases respectively. The correctness and feasibility of the theory are verified by using MATLAB experimental simulation, and the results also show that the change of vehicle speed and position affects the vehicle collision.关键词
