The embodiment of the invention discloses a driving vehicle safety early warning method and system for an expressway, relates to the technical field of intelligent traffic vehicle-road cooperation, and is used for solving the problems that an existing early warning mode is small in early warning range and single in early warning type. The method comprises the following steps: acquiring driving data of a driving vehicle through a preset millimeter wave radar on a highway section; performing data elimination on the driving data according to a preset target reflecting surface energy threshold value, a preset effective acquisition range of the millimeter wave radar and a preset speed threshold value so as to obtain target driving data; performing behavior recognition on the target driving data based on a preset expressway event comprehensive sensing algorithm to obtain an event type of the expressway section; and determining the danger level of the highway section according to the event type, and sending the danger level and the event type to a vehicle-mounted mobile terminal of a backward vehicle located on the highway section based on a TCP/IP (Transmission Control Protocol/Internet Protocol).

    本说明书实施例公开了一种用于高速公路的行驶车辆安全预警方法及系统,涉及智能交通车路协同技术领域,用于解决现有预警方式预警范围小且预警类型单一的问题。方法包括:通过高速公路路段上的预置毫米波雷达采集行驶车辆的行驶数据;根据预置目标反射面能量阈值、预置毫米波雷达的有效采集范围以及预设速度阈值对行驶数据进行数据剔除,以获得目标行驶数据;基于预置高速公路事件综合感知算法对目标行驶数据进行行为识别,获得所述高速公路路段的事件类型;根据事件类型确定高速公路路段的危险等级,并基于TCP/IP协议将所述危险等级与所述事件类型,发送到位于高速公路路段后向车辆的车载移动终端。
