Preliminary concept of urban air route intersection operation for UAV

With the development of emerging technologies such as the Internet of Things and cloud computing, the UAV industry has been iteratively updated, accelerating the integration of UAVs into urban airspace. The air route network is the medium of UAV flight, which can guide high-density UAV flight in an orderly manner. As the key node of the air route, the intersection carries the function of traffic flow convergence and diversion. This paper provides the preliminary concept and operation description of urban air route intersections. Through simulation experiments, the operation characteristics of UAVs are quantitatively analyzed from two levels of safety and efficiency. The results show that when the total number of UAVs is a constant value, the maximum average conflict probability and average passing time of UAVs grow with the increase of the number of connecting routes at the intersection. The concept of intersection operation proposed in this paper can provide guidance for the orderly flight of UAVs, and improve the intersection service ability to a certain extent.
