摘要
跟踪过滤京津石多机场系统实时航迹点数据,搭建包括航迹网络、航迹簇流量模式、航迹管交叉空域和航迹相态4个方面的多机场系统航空流运行结构集成检测框架,经分类、分组、分层、分相对邻近流、并发流、多变量流、集体流进行检测发现:由少量中心航迹形成主导性流向,4组航迹簇流量模式持续时间均较长且存在时间窗口集中与分散分布差异,在航迹管交叉空域表现为穿越关系并可同时共享同一空域单元,航迹相态受航空流参与量和航空网络影响而发生时序变化。与纽约多机场系统对比,中心航迹偏少且流向域面较窄、航迹簇流量模式和航迹管交叉空域持续集中时间较长且可变性较小、航迹拥堵相出现频率更高。大兴机场加入后将新增中心航迹、消减时间窗口峰值并引发形成新的交叉空域。揭示出航空地理市场的基础性作用,可为多机场系统空域动态配置与系统协调提供决策支持。
The real-time flight trajectory data of Jing-Jin-Shi multi-airport system was obtained by tracking and filtering,and an integrated detection framework for air flow operation structure of multi-airport system including trajectory network,trajectory cluster flow pattern,trajectory tube in crossing airspace and trajectory phase state was built.Through classification,grouping,layered and phased detection of adjacent flow,concurrent flow,multivariable flow and collective flow,it is found that:A small number of central trajectories can form a dominant air flow operation.The four groups of trajectory cluster flow patterns all last for a long time and there are differences in the concentration and dispersion of sliding windows.The spatio-temporal interaction of air traffic flow among the trajectory tube in crossing airspace is shown as a crossing relationship and also shares the same airspace unit at the same time.Besides,the phase state changes due to the influence of air flow participation and aviation network.Compared with the New York multi-airport system in the United States,the central trajectories are less and the flow direction area is narrower.Secondly,the trajectory cluster flow pattern and the trajectory tube in crossing airspace have longer concentration time and less variability,and the trajectory congestion is more likely and more frequent.The participation of Beijing Daxing International Airport will increase the central trajectories,reduce the peak value of sliding windows and also make the new crossing airspace.This research reveals the fundamental role of the aviation geographic market,which can provide decision-making for the dynamic airspace configuration and coordination of multi-airport system.
