Embodiment Construction

[0036] The present invention will be further described below in conjunction with accompanying drawing.

[0037] 1. Construction of traffic flow characteristic index system

[0038] Through repeated communication with relevant researchers, controllers of operating units, and management, combined with the extracted air traffic radar trajectory data in different regions, the characteristic parameter index system of air traffic flow is finally obtained. refer to figure 1 , the index system is as follows:

[0039] 1. Flight flow attribute characteristic index

[0040] The flight flow attribute characteristic index can start from the perspective of microscopic aircraft operation, and according to the kinematic process, it can be divided into acceleration, average speed, heading, flight time, aircraft position, and the average interval and The average speed when passing through a certain area, the first points are the five elements of a single aircraft, and the last two points foc...

Abstract

The invention discloses a method for extracting a parameter index in an air traffic flow characteristic parameter index system. Based on the information provided by air traffic control radar data, a set of systematic air traffic flow characteristic parameter index system is designed according to requirements of an operation unit for traffic flow research, and the definition of an index and a method for extracting the index are given. The characteristic index system comprises a flight flow attribute characteristic index, an operational safety characteristic index and an operational efficiency characteristic index. The calculation result of characteristic parameter values reflects the movement state and complexity of air traffic flow, and the change of a traffic flow state can be reflected by the comparison of the continuous indexes at different time periods. The quantitative description and assessment of the operational state of the air traffic flow are carried out, and basic data analysis method and technique are provided for researchers and users to understand, know and optimize the traffic flow.

Description

technical field [0001] The invention relates to the field of air traffic, in particular to a method for extracting parameter indexes in an air traffic flow characteristic parameter index system. Background technique [0002] Due to the continuous increase of air traffic demand, under the existing operating environment, there is a mismatch between demand and capacity in some areas of the air or in a short period of time, resulting in phenomena such as air traffic congestion, dangerous approach, and flight delays. In order to better analyze the causes and development trends of the above phenomena and better control the operating efficiency of traffic flow, it is necessary to sort out and analyze the characteristics of the current situation of traffic flow in the existing entire traffic operating environment, and establish quantifiable indicators system. Through the calculation, analysis and comparison of these indicators, we can master, control and optimize the distribution a...
