Application of UAV in Road Safety in Intelligent Areas.

With the continuous development of remote sensing(RS) technology, the surface information can be collected conveniently and quickly by using the popular unmanned aerial vehicle(UAV). The application of UAV low altitude RS technology in road safety in intelligent area has certain practical significance. It can provide safety warning for most drivers, and provide auxiliary decision-making for the road supervision department. Through the collection, processing, calculation and analysis of the road image, the UAV can find out the road obstacles with potential safety hazards, identify the road pit, calculate the radius and depth of the road pit through the digital mapping system, predict the accident risk according to different speed and provide scientific basis for the road safety monitoring. At the same time, UAV can provide repair scheme for damaged roads, estimate the quantity of materials needed for repair, and achieve the target of resource saving and efficiency improvement. The experimental results show that the UAV can not only provide scientific prediction information for driving safety, but also provide relatively accurate material consumption for road repair.
