A method for establishing the classification index of air intersections

Abstract

The present invention provides an air cross point grading index establishing method. The method comprises the steps of: setting grading index values of air cross points and a calculation model thereof; establishing a complexity calculation model, and calculating a total complexity of the air cross points; establishing a collision risk value calculation model, and calculating a total collision riskvalue of the cross points; substituting the total complexity and the collision risk values into the grading index value calculation model, and calculating grading index values of the air cross points; and performing classification of the air cross points according to the grading index values, and determining whether an overpass bridge is established or not according to the sizes of the grading index values. The air cross point grading index establishing method performs grading of the air cross points according to the indexes such as operation complexity (main flow distribution), operation risks and the like, overcomes defects that a single index, such as a whole-day over-point flow statistical value, is used to perform grading of the air cross points to cause generality and imperfection,and gives a standard of determining whether the overpass bridge is established or not according to the operation complexity and the operation risk degree. The air cross point grading index establishing method is simple and accurate in implementation.

Description

technical field [0001] The invention belongs to the technical field of civil aviation, and in particular relates to a method for establishing an air intersection classification index. Background technique [0002] Air intersections are an important part of the airway network. Air overpasses are a control strategy used by Chinese controllers when deploying conflicts at busy air intersections. Safety plays an important role in reducing the controller's load. However, due to the fact that there are more and more aerial overpasses at present, and they have evolved into "air viaducts" in some places, regardless of the flow and airspace structure, the height limit is "limited to the boundary" and continues to spread, and "living overpasses" have become "dead However, it is not possible to flexibly allocate height levels according to the actual level occupancy, which seriously affects the efficiency of the air traffic control system. [0003] Because the air overpass is a way for...

Problems solved by technology

The literature on aerial overpass research is only an article "The Impact of One-way Circulation Airway Reconstruction on Air Overpass" published by Yang Chao, Air Traffic Management Bureau of the Civil Aviation Administration of China in 2013; there is no direct reference to deal with the same problem abroad

[0004] The following problems exist in the currently commonly used methods for establishing classification indicators for air intersections: to classify air intersections only based on a single index, such as the statistical value of passing traffic throughout the day, the disadvantage is that it is relatively general and not comprehensive, and does not consider the operational complexity , operational risk and other factors
