Research and Prospects of Unmanned Aerial Vehicle Traffic Surveillance and Emergency Response in Multiple Scenarios

The road safety problem caused by traffic accidents(a pileup, overspeed collision, drunk driving collisions and so on.) has always been a hot topic, which seriously threatens the social stability and economic development. The traditional methods of traffic state detection are mainly manual check or identification of relevant traffic parameters by road side cameras. These methods generally have the disadvantages of low efficiency, slow speed, low accuracy and slow data processing. So, equipment that can detect quickly and accurately is needed. Compared with traditional methods, Uavs are highly mobile and flexible, and with the continuous improvement of computer processing power, the combination of the two will have great application advantages in accident handling, order management, traffic guidance, and vehicle flow detection. Combined with the current situation of UAV traffic monitoring, this paper summarizes the research progress of UAV in traffic monitoring, and looks forward to the future research and development trend.
