城市道路交叉口防碰撞预警的研究

Research on collision avoidance warning in urban road intersection

城市道路交叉路口被认为是交通事故发生概率比较高的区域,文章详细分析了城市交叉路口碰撞预警算法及其存在的不足之处,对改进的算法进行论述。基于C-V2X交叉碰撞预警,通过车、路、人和基础设施数据信息共享和互联,准确预测车辆轨迹,给出行驶建议速度,有效解决城市交叉路口碰撞安全问题。

Urban road intersection is considered to be an area with high probability of traffic accidents.This paper analyzes the collision warning algorithm and its shortcomings in detail,and discusses the improved algorithm.Based on the C-V2X cross collision warning,through the sharing and interconnection of vehicle,road,human and infrastructure data and information,the vehicle trajectory is accurately predicted,the speed of driving suggestion is given,and the collision safety problem of urban intersection is effectively solved.
