The invention discloses a road traffic safety monitoring method and device and a medium, and the method comprises the steps: obtaining a road image of a road region in a preset period; inputting the road image into a pre-trained vehicle identification neural network model, and outputting vehicle information of the road area; judging whether the vehicle flow exceeds a preset flow threshold value or not; if yes, matching the vehicle flow in a pre-generated signal lamp conversion period mapping table of the road area to obtain a temporary signal lamp shortened conversion period corresponding to the vehicle flow; the larger the vehicle flow is, the shorter the temporary signal lamp shortening conversion period is; according to a difference value between the vehicle flow and a preset flow threshold value, first control time for shortening the conversion period of the temporary signal lamp is determined; and in the first control time, the signal lamp conversion period of the road area is adjusted to be the temporary signal lamp shortened conversion period. And the road traffic safety monitoring efficiency is improved.
本申请公开了一种道路交通安全监测方法、设备及介质,方法包括:在预设周期内,获取道路区域的道路图像;通过将道路图像输入预先训练的车辆识别神经网络模型,输出道路区域的车辆信息;判断车辆流量是否超过预设流量阈值;若是,则在预先生成的道路区域的信号灯变换周期映射表中,对车辆流量进行匹配,得到车辆流量对应的临时信号灯缩短变换周期;车辆流量越大,临时信号灯缩短变换周期越短;根据车辆流量与预设流量阈值之间的差值,确定临时信号灯缩短变换周期的第一控制时间;在第一控制时间内,将道路区域的信号灯变换周期调整为临时信号灯缩短变换周期。提高道路交通安全监测效率。
