The invention relates to a self-adaptive variable lane control method, which comprises a central platform, the central platform is simultaneously connected with a guide screen and an intersection terminal, the central platform sets interval detection duration and sends a request message to the intersection terminal, and the intersection terminal replies an image acquired by a camera as real-time data to the central platform. And the central platform judges whether the variable lane needs to be switched according to the returned real-time data, if the variable lane needs to be switched, a message is sent to the intersection terminal, the intersection terminal records the data to a database and adds a log, corresponding switching display is carried out through the induction screen, and if the variable lane does not need to be switched, processing is not carried out. Therefore, switching between the straight-going function and the left-turning function of the variable lane can be dynamically controlled, road traffic development with variable traffic flow characteristics can be actively adapted, benefits of the variable guide lane can be fully played, and supersaturated congestion of left-turning or straight-going at the peak period of an intersection can be effectively relieved.
本发明涉及一种自适应可变车道控制方法,包括有中心平台,所述中心平台上同时连接有诱导屏与路口终端,由中心平台设置间隔检测时长,向路口终端发送请求报文,路口终端将摄像头获取的图像作为实时数据回复至中心平台,中心平台根据返回的实时数据判断是否需要切换可变车道,若需要切换,则发送报文至路口终端,路口终端记录数据到数据库与添加日志,并通过诱导屏进行相应切换显示,若否,则不做处理。由此,可以动态的控制可变车道的直行功能和左转功能的切换,主动适应交通流特性多变的道路交通发展,使可变导向车道的效益得到充分发挥,有效缓解交叉口高峰时段的左转或直行的过饱和拥堵。
