The invention relates to a highway variable speed limiting method for emergencies. The method comprises the steps that a highway is divided into a plurality of different sections through variable speed limiting plates; acquiring flow data of each section in real time through expressway sensing equipment; whether an emergency occurs or not is judged in combination with sensing information of highway sensing equipment and vehicle report information, if yes, whether section speed limiting needs to be carried out or not is further judged according to the type of the emergency and the real-time flow of each section, and if yes, the section speed limiting needs to be carried out; and if yes, solving the speed limit value of each section at the upstream of the emergency, and correspondingly sending the speed limit value to the variable speed limit plate of each section for display. Compared with the prior art, the method has the advantages that the upstream arrival flow can be effectively reduced by setting the section speed limit at the upstream of the emergency occurrence point, so that the rapid spreading of congestion is delayed, the expressway management and control means can be enriched, the drivers can be timely and effectively guided to limit the speed, and the method is high in novelty, high in timeliness, good in fault tolerance and the like.

    本发明涉及一种面向突发事件的高速公路可变限速方法,包括:利用可变限速板将高速公路划分为多个不同区段;通过高速公路感知设备,实时获取各区段的流量数据;结合高速公路感知设备感知信息以及车辆上报信息,判断是否发生突发事件,若判断为是,则根据突发事件类型以及各区段的实时流量,进一步判断是否需进行区段限速,若判断为是,则求解突发事件上游各区段的限速值、并将限速值对应发送至各区段的可变限速板进行展示。与现有技术相比,本发明通过设置突发事件发生点上游的区段限速,能有效降低上游到达流量,从而延缓拥堵的迅速蔓延,能丰富高速公路管控手段,对驾驶人员进行及时有效的引导限速,具有新颖性强、时效性高和容错性好等优点。
