The invention discloses a highway coordination control method in foggy weather based on a cellular automaton model. According to the control method, a highway system composed of a multi-entrance ramp,a main line, an interchange overpass intersecting with other highways, visibility detection equipment, a wide-area radar, video acquisition and the like is used as an application object, the CAM of all road sections in foggy weather is established according to the technical characteristics of the highway, the maximum speed limit value and the maximum allowable flow of each road section under different visibility are determined, and the maximum speed limit value of each road section and the optimal vehicle release amount of each entrance ramp are determined according to the weather and the information acquired by a traffic flow detection sensing system during specific implementation. On the premise that the traffic safety of the highway is guaranteed, refined fusion management and controlmeasures are implemented, the requirement for quasi-all-weather highway passing is met, the traffic flow of the highway is increased, and unnecessary ramp queuing time is shortened.
本发明公开了一种基于元胞自动机模型的雾天高速公路协调控制方法,该控制方法以多出入口匝道、主线、与其它高速交汇的互通立交桥、能见度检测设备、广域雷达、视频采集等组成的一条高速公路系统为应用对象,依据高速公路的技术特点,建立各路段雾天CAM,确定各路段不同能见度下的最大限速值和最大容许流量,在具体实施时依据气象和交通流检测感知系统所采集的信息,确定各路段最大限速值和各入口匝道最佳放车量,使高速公路保证交通安全的前提下,实施精细化融合管控措施,满足准全天候高速公路通行的要求,提高高速公路车流量、减少不必要的匝道排队时间。
