The invention discloses a main line priority space-time cooperative control method for a highway ramp confluence area. Comprising the steps that a road section management unit obtains vehicle running state information, pre-compiles running tracks for all vehicles, and sends the running tracks of all vehicles to all vehicles through V2I communication, and all vehicles know the driving intention of each other and the confluence process of all vehicles. The invention provides a method for pre-compiling driving tracks of vehicles before ramp vehicles converge, and a method for calculating a safe distance between vehicles in a vehicle-road depth cooperation scene is deduced; on the basis of the acceleration when the vehicles collide, the critical degree of the vehicle conflicts is quantitatively evaluated, and before the vehicles collide, conflicts are eliminated, congestion is effectively reduced, traffic safety and efficiency are improved, delay of ramps and main lines is greatly reduced, and confluence efficiency and traffic flow stability are improved.
本发明公开一种高速公路匝道合流区的主线优先时空协同控制方法。包括由路段管理单元实施获取车辆运行状态信息,并对所有车辆预先编制运行轨迹,将所有车辆的运行轨迹通过V2I通信再发送给各个车辆,并且各个车辆之间互相知道对方的驾驶意图所有车辆的合流过程。该发明提出一种匝道车辆在合流之前预先编制车辆的行驶轨迹的方法,推导了在车路深度协同场景下车辆之间的安全距离计算方法;以车辆发生碰撞时的加速度为基础,量化评估了车辆发生冲突的紧要程度,在车辆产生冲突产生之前,消除冲突,有效减少拥堵并提升了交通安全和效率,大幅减少了匝道和主线的延误,提高了合流效率和交通流的稳定性。
