A UAV-based traffic recognition method for expressway emergencies

Abstract

The invention discloses a traffic identification method under a highway emergency based on an unmanned aerial vehicle. The traffic identification method is mainly used for solving the problem that a current highway is congested for a long time in the event of the emergency. According to the traffic identification method, the industrial-grade unmanned aerial vehicle is taken as a carrier, and thusthe emergency is monitored for the first time; and the traffic identification method relates to the steps that information of the the highway emergency is obtained quickly and efficiently through thepolice unmanned aerial vehicle, traffic basic parameters of the incident point are extracted, the impact range of the emergency is judged, an upstream entrance ramp in the impact range is determined,a series of dispersion process of traffic at the incident point is conducted by closing the upstream entrance ramp, and finally, whether traffic dispersion is completed or not is judged through the unmanned aerial vehicle; and in the dispersion process, professional personnel can command site rescue through a loudspeaker carried by the unmanned aerial vehicle. According to the traffic identification method, quick monitoring and traffic dispersion work of the highway emergency are achieved, the traffic congestion situation is relieved, and property losses are reduced.

Description

technical field [0001] The invention relates to the field of road section traffic guidance, in particular to a traffic recognition method based on an unmanned aerial vehicle under expressway emergencies. Background technique [0002] At present, the construction mileage of expressways in our country is constantly increasing, and the traffic flow is also increasing. At the same time, emergencies on expressways in our country often occur, but the emergency rescue capabilities of relevant departments in our country for expressway emergencies are still limited. relatively weak. Once a major emergency occurs on the expressway, due to the relatively lagging traffic guidance behavior in our country, a traffic jam zone several kilometers long will be formed in a short period of time, resulting in long-term traffic jams, coupled with the emphasis on emergency lane management measures If it is not enough, it will easily lead to blockage of the emergency lane, causing the rescue team ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problem of long-term congestion of the current expressway once an emergency occurs, and to provide a traffic guidance technology for unmanned aerial vehicles in the event of an expressway emergency, using industrial-grade unmanned aerial vehicles as a carrier to achieve the first Timely monitoring of emergencies, fast and efficient extraction of basic traffic parameters of the upstream section of the incident point, and a series of traffic diversion processes at the incident point by closing the upstream entrance ramp to realize rapid monitoring and diversion of expressway emergencies
