摘要/Abstract

摘要：

针对十字路口处的车辆碰撞现象,提出一种基于碰撞点时间估计的车辆碰撞预警算法,以降低交通事故发生概率,提高十字路口处车流的流畅程度。在考虑交通信号灯控制的情况下,分析十字路口处车辆碰撞的不同场景,并给出碰撞点位置和车辆到达碰撞点时间的估计方法。MATLAB实验结果验证了该算法的正确性和可行性,同时表明车辆速度和位置的变化都会对车辆碰撞情况造成影响。

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.

Key words: collision warning algorithm, intersection, collision point, Time to Collision Point(TTCP), vehicular ad-hoc network
