The invention discloses a traffic signal control method and device for a road intersection, and a medium. The method comprises the following steps: obtaining a corresponding historical road image set of each phase of a road intersection in a preset time period; determining the vehicle queuing length and the vehicle queuing number of each lane corresponding to each phase; obtaining the number of passed vehicles of each lane corresponding to each phase; calculating the average value of the vehicle queuing lengths of the lanes corresponding to the phases as the average vehicle queuing length of the phases; calculating the average number of passed vehicles of each phase; determining a green light adjustment value of the phase according to the average vehicle queuing length, the average number of passed vehicles and the current green light duration of the phase; determining the green light time of the phase in the next time period based on the green light adjustment value and the current green light duration; and adjusting the current traffic signal timing scheme based on the green light time of the next time period of each phase so as to control the traffic signal of the next time period of the road intersection.
本申请公开了一种用于道路交叉口的交通信号控制方法、设备及介质,通过获取道路交叉口的各相位预设时间段内对应的历史道路图像集合。确定各相位对应的各个车道的车辆排队长度、车辆排队数。以及获取各相位对应的各个车道的已通过车辆数。计算各相位对应的各个车道的车辆排队长度的平均值,作为相位的平均车辆排队长度。以及计算各相位的平均已通行车辆数。根据平均车辆排队长度、平均已通行车辆数以及相位的当前绿灯持续时间,确定相位的绿灯调整值。基于绿灯调整值以及当前绿灯持续时间,确定相位下一时间段的绿灯时间。基于各相位的下一时间段的绿灯时间,调整当前的交通信号配时方案,以控制道路交叉口下一时间段的交通信号。
