Air-ground coordination-based expressway emergency disposal simulation system and assistant decision making method

Abstract

The invention discloses an air-ground coordination-based expressway emergency disposal simulation system and an assistant decision making method. The system comprises an unmanned aerial vehicle group,an unmanned aerial vehicle foundation assembly and an industrial computer. As a vehicle-mounted device for emergency command, the device can quickly reach a nearby location after an expressway emergency event, and has high flexibility and mobility; the advantages of flexible unmanned application means, abundant application scenarios and wide data acquisition are made full use of, the system and the method can be timely used for on-site information collection when the expressway emergency event happens, and the response speed of emergency disposal is ensured; an emergency disposal strategy simulation mode is applied, the implementation process of the strategy is previewed in advance, the implementation effects are evaluated to assist a field commander to make a better decision, the purposeof improving the decision making precision is achieved, and risks brought by a poor emergency disposal strategy are reduced at the same time.

Description

technical field [0001] The invention relates to the field of expressway traffic emergency management, in particular to an expressway emergency response simulation device and an auxiliary decision-making method based on air-ground coordination. Background technique [0002] Expressways are an important part of the road transport network. In the operation of the expressway, due to the high speed of vehicles and the high proportion of heavy-duty vehicles, once an emergency occurs, it will often cause more serious traffic accidents than urban roads, resulting in the closure of some lanes, limited road capacity, and small-scale accidents. If the emergency response is not timely, it is likely to cause secondary accidents, and the congestion will be traced back to the upstream section, and some sections or even the entire section will be closed, resulting in large-scale regional congestion. [0003] When adopting an emergency response strategy, most of the existing methods are bas...

Problems solved by technology

[0005] The present invention aims at the problem that it is difficult to be both "fast" and "good" at the same time in the existing emergency response strategies, that is, when the existing methods increase the emergency response speed of expressways, it is often difficult to ensure the fault tolerance, flexibility and accuracy of the response strategies problem, a highway emergency response simulation device based on air-ground coordination and an auxiliary decision-making method are proposed
