The invention discloses a vehicle scheduling method and system for an intersection without a signal lamp, and the method comprises the steps: obtaining to-be-passed vehicles at the intersection without the signal lamp, and dividing the to-be-passed vehicles into a vehicle team form; determining two motorcades closest to the intersection, and judging whether the moving trajectories of the two motorcades passing through the intersection have an overlapped region or not; if not, the two motorcades do not collide with each other, and the two motorcades are controlled to normally pass through the intersection; if yes, the two motorcades have the possibility of collision, and the overlapping area is the possible collision area; calculating the time when the two motorcades arrive at the possible collision area, controlling the motorcade which firstly arrives at the possible collision area to pass preferentially according to the principle of coming first and then passing later, and controlling the other motorcade to pass later; judging whether the two motorcades collide with each other when passing through the intersection at the current speed or not; if yes, controlling the latter passing fleet to decelerate, and if not, controlling the latter passing fleet to accelerate. According to the invention, the problem that the intersection with small traffic flow is easy to jam and collide can be solved.
本发明公开了一种无信号灯路口的车辆调度方法及系统,该方法包括:获取无信号灯路口的待通行车辆,将其划分成车队形式;确定离路口最近的两个车队,判断所述两个车队通过路口时的运行轨迹是否存在重叠区域;若否,则两个车队不会发生碰撞,控制两个车队正常通过路口;若是,则两个车队存在发生碰撞的可能,重叠区域即为可能的碰撞区域;并计算两个车队到达所述可能的碰撞区域的时间,按照先来后到的原则控制首先到达所述可能的碰撞区域的车队优先通行,控制另一车队后通行;判断两个车队以当前速度通过路口时是否会发生碰撞;若是,则控制后通行的车队减速,若否,则控制后通行的车队加速。本发明能够解决车流量较小的路口易拥堵、碰撞的问题。
