The invention discloses a traffic control method for an urban intersection mixed with automatic driving vehicles. The method is used for carrying out signal timing on the urban intersection based on the traffic flow with mixed driving of the automatic driving vehicles and the manual driving vehicles, and comprises the steps: firstly, collecting the traffic flow of an intersection and the number ofleft-turn lanes and straight lanes in each entrance direction, and then, establishing calculation methods for the average time headway of a single lane and the maximum flow ratio in each phase; establishing calculation methods for green light duration and the single-lane traffic capacity; and finally, determining an optimal traffic control scheme according to the target with the maximum traffic capacity at the intersection. The method aims to perform reasonable urban intersection signal timing for mixed traffic flow of automatic driving vehicles and manual driving vehicles in the future, so that the intersection traffic capacity is improved, and traffic jam is relieved.

    本发明公开了一种混入自动驾驶车辆的城市交叉口交通控制方法。基于自动驾驶车辆和人工驾驶车辆混行的交通流,对城市交叉口进行信号配时。首先采集交叉口的交通流量以及各进口方向的左转和直行车道数,然后建立单车道平均车头时距和各相位中最大流量比的计算方法;之后建立绿灯时长和单车道通行能力的计算方法;最后根据交叉口通行能力最大的目标,确定最佳交通控制方案。本发明旨在面向未来自动驾驶车辆和人工驾驶车辆混行的交通流,进行合理的城市交叉口信号配时,从而提高交叉口通行能力,缓解交通拥堵。
