The invention relates to an intelligent traffic light duration setting method and device. The method comprises the following steps that a camera obtains a road image and sends the road image to a controller; the controller receives and processes the road image to obtain the number of vehicles waiting for passing; the number of vehicles waiting for passing on the two sides of one road is obtained, the average value k1 is obtained, and the number of vehicles waiting for passing on the two sides of the other road is obtained, and the average value k2 is obtained; judging the size of k1 and k2, and setting the larger value as k; based on the value of k, the green light duration of the crossroad is formulated; repeating the above steps every second preset time, and adjusting the traffic light duration; crossroad road images are obtained regularly, vehicle queuing conditions are obtained through analysis and processing, and the duration of each signal lamp of the traffic light is adjusted in real time, so that the requirements of people on the duration of the traffic light at different time and different places are met, and the condition of road congestion caused by unreasonable setting of the duration of the traffic light is reduced.

    本申请涉及一种智能红绿灯时长设置方法和装置,包括以下步骤:摄像头获取道路图像并发送给控制器;控制器接收到道路图像并进行处理,得到等待通行的车辆数量;获取一条道路两侧分别等待通行的车辆数量并取平均值k1以及另一条道路两侧等待通行的车辆数量并取平均值k2;判断k1与k2的大小,将较大值设为k;基于k的数值,制定所述十字路口的绿灯时长;每间隔第二预设时间,重复执行上述步骤,对红绿灯时长进行调整;通过定时获取十字路口道路图像,经过分析处理得到车辆排队情况,进而实时调整红绿灯各信号灯的时长,以满足人们在不同时间不同地点对红绿灯时长的要求,减少因红绿灯时长设置不合理造成道路拥堵的情况。
