| 摘 要： | 空中廊道作为一种新型航空流组织与空域资源分配方式,是一种复杂的航空流网络,解析其结构特征并评估其结构性能是实现空域资源动态配置的前提。该文通过构建网格时空图方法,以京—成空中廊道为例进行航空流网络解构研究,包括基于航迹簇的网络构型、流量时空波动与航空流聚合分化三方面,据此提出空域资源动态配置方案。研究结论如下:1)以多种邻近阈值指示航迹交叉角度持续增大,检测出航空流网络存在平行流、交叉流、全覆盖流和半覆盖流4种构型,基于其占比和特征的显著差异性提出并行扩容调整方案;2)以高频数网格点状或短线状集中分布指示流量时空波动,检测出航空流网络存在两个不同内涵的时间高峰、以距离中值区为近似对称轴的空间高峰以及在区段间漂移的时空交互高峰,进而提出时间错峰调整方案;3)以网格属性指示聚合分化点的分布,检测出航空流网络阶梯递减、高值集聚和叠合特征,相应提出动态快速分化分流调整方案。

| 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 corridor-in-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 of track cluster structure including parallel flow,cross flow,full 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 of air traffic flow is indicated by the points or short lines concentrated distribution of 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 drifting 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. |
