基于宏观基本图的空中交通流运行状态诊断与识别研究

Research on Diagnosis and Recognition of Air Traffic Flow Operation State Based on Macro Fundamental Diagram

为了实时准确识别交通流交通状态,结合宏观基本图(Macroscopic Fundamental Diagram)特性,提出一种航空路网交通状态识别方法。通过类比国内外学者研究地面交通流方法去研究空中交通流,以过点时间数据为基础,选取上海05扇区的航路(线)作为研究区域,收集一天的航班流量以及仿真过后的航班流量,研究其宏观基本图(MFD),从宏观角度分析宏观基本图的存在性及存在条件。为了解决不断增加的航空运输需求、航班延误、空域拥挤、以及飞行冲突等现实问题,需要正确地识别空中交通流特征,并采取一系列措施。诸如,发布流控、调整飞行间隔、合理划分扇区。空域资源是有限的,通过这些手段,来达到流量最大化的目的。

In order to recognize traffic flow status accurately in real time,a traffic status recognition method for air traffic network is proposed based on the characteristics of macroscopic fundamental diagram(MFD).Based on the transit time data,the route of Shanghai 05 sector is selected as the research area.The flight flow of one day and the simulated flight flow are collected to study MFD and the existence and conditions for the existence of MFD are analyzed from the macro-degree.In order to solve the increasing demand for air transport,flight delays,airspace congestion,flight conflicts and other practical problems,it is necessary to correctly identify the characteristics of air traffic flow and take a series of measures,such as releasing flow control,adjusting flight interval and dividing sector reasonably.Airspace resources are limited,and through the above means,the purpose of maximizing traffic is achieved.
