协同式道路交叉口防碰撞模型仿真研究
|
摘要
城市交通中,道路交叉口作为车辆汇集、转弯和疏散的必经之地,交通态势极其复杂,是交通事故的多发区域。针对交叉口安全问题,在不牺牲城市道路交叉口通行效率的基础上,建立协同式防追尾碰撞模型和防侧碰撞模型,确定模型输入输出参数。同时,利用Matlab的Simulink模块将模型转换为逻辑图进行求解,结合Prescan软件搭建的协同式交叉口仿真平台,通过改变输入参数进行仿真并对比分析。结果表明,模型对于通过交叉路口车辆控制的过程是趋向于高效且安全的,可降低交叉口碰撞的概率,且可通过车辆中油门开度和相应车辆扭矩关系判断车辆行驶状态,从而验证模型防碰撞过程及应用可行性。
Acting as a must passing through area for vehicle collection,turning and evacuation,the traffic situation of urban road intersection is extremely complex and has become a traffic accident prone area. As for the safety problem of road intersection,this paper established the rear-end collision model and anti-roll collision model of cooperative road intersection and determined the models' input and output parameters without sacrificing traffic efficiency at urban road intersections. At the same time,the model was transformed into logic diagram to solve the problem based on the Simulink module in Matlab software,and a cooperative intersection simulation platform was built by combining Prescan software and carry out the simulation experiment via changing input parameters. The results show that the model is more efficient and safer for the process of vehicle control through the intersection,which can reduce the collision probability at road intersection and judge the running state of vehicle by the relationship throttle opening degree and corresponding output torque,thus verifying the anti-collision process and the feasibility of the model.
