A system and method for predicting and deriving national flight traffic spatio-temporal distribution

Abstract

The invention discloses a national flight flow space-time distribution prediction deduction system and method. The prediction deduction system includes an airspace structure module, a basic data module, a flight demand prediction module, a flight flow space-time distribution prediction deduction module, and an analysis display module. The first three modules are used for storing and maintaining national flight flow relevant data, and the last three modules face the actual analysis and application of the national flight flow prediction deduction. The method constructs a typical daily national initial flight plan in the future based on the prediction of future flight demands of national airports, realizes the deduction and prediction of the national flight flow on the basis of the typical daily national initial flight plan, and obtains flight flow space-time distribution of each kind of airspace units in the conditions of capacity restriction, airspace restriction, and navigation influence. The national flight flow space-time distribution prediction deduction system and method practically provide a decision basis for newly rebuilt airports, air routes, sector structure optimization and flight time formulation of our country, and promote the rationality and scientificity of strategic flight flow management decisions.

Description

technical field [0001] The invention relates to the field of air traffic flow management and planning, in particular to a forecasting and deduction technology for the temporal and spatial distribution of national flight flow. Background technique [0002] With the rapid development of my country's air transport, the contradiction between airspace and flight demand has become increasingly prominent, and the current airspace operation management mode and flow control method are difficult to meet the continuous growth of flight flow needs. In order to improve my country's flight flow management level and promote a refined and scientific flight flow management mechanism, it is urgent to overcome the national flight flow forecasting and deduction technology. On the one hand, it can provide national flight demand forecast data, which is conducive to grasping my country's future from a national level. The flight demand within a certain period of time provides data support for the op...

AI Technical Summary

Problems solved by technology

[0003] At present, there are abundant theoretical research results on flight demand forecasting, but there are few technologies that can be applied to the actual engineering of air traffic in my country. Foreign countries have gradually established and improved the flight demand forecasting rolling update mechanism. , unable to copy advanced foreign technologies; in addition, there are few theoretical studies on flight flow deduction in wide airspace, and the existing research results mainly focus on short-term flight trajectory prediction, and there is a lack of relevant technology and system support in the deduction of temporal and spatial distribution of air traffic flow
