- Abstract
As a new way of air traffic flow organization and airspace resources allocation, corridor in-the-sky itself constitutes a complex air traffic flow network. Analyzing its structural characteristics and evaluating its structural performance is the premise of realizing the dynamic allocation of airspace resources・ In this paper, a spatio-temporal grid map method is proposed to study the deconstruction of air traffic flow network・ Taking Beijing-Chengdu corridorflin-the-sky as an example, three main aspects are included: track cluster structure, spatiotemporal flow density fluctuation and aggregation differentiation of air traffic flow・ The major contents and results are summed up as follows. 1) Multiple adjacent thresholds are used to indicate the angle continuous increase of track intersection, and four kinds ol track cluster structure including parallel flow, cross flow, lull coverage flow and half coverage flow are detected in the air traffic flow network, and then a parallel expansion adjustment scheme is proposed based on the significant difference of its proportion and characteristics・ 2) The spatio-temporal density fluctuation ol air traffic flow is indicated by the points or short lines concentrated distribution ol high frequency grid. Two time peaks with different connotations and the spatial peak of the approximate symmetrical axis with the median distance area along with the spatio-temporal interaction peaks drilling between segments are detected in the air traffic flow network・ Then the time peak shifting adjustment scheme is proposed・ 3) The distribution of aggregation differentiation points in the air traffic flow network is indicated by the track attribute in the grid, and the characteristics of step decline, high value clustering and superimposition are detected. Then a dynamic and fast flow diversion adjustment scheme is proposed・ This research is an active exploration of the dynamic allocation of airspace resources.
