Embodiment Construction

[0018] The method for measuring the complexity of air traffic based on the two-layer multi-level network model provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 Shown, the air traffic complexity measurement method based on the two-layer multi-level network model provided by the present invention comprises the following steps carried out in order:

[0020] Step 1) Collect air traffic control radar data: According to the air traffic control radar display cycle, collect the data of the radar once every 4 seconds, and extract the aircraft target and its position information; The above information is coarse-grained once, and the longitude, latitude, altitude, speed, and heading information of all aircraft targets in this period are averaged as the aircraft information of the current period;

[0021] Step 2) Construct a two-layer multi-level network model based on the...

Abstract

Provided is a method for measuring air traffic complexity based on a double-layer multi-stage network model. The method includes the following steps: (1) acquiring air traffic control radar data; (2) building the double-layer multi-stage network model according to the information acquired in the step (1); (3) calculating network indexes by utilizing the double-layer multi-stage network model; (4) forming a complexity vector based on the calculated network indexes. The method for measuring air traffic complexity based on the double-layer multi-stage network model is an objective assessment method of air traffic complexity. By means of the method, the two-dimensional and three-dimensional complexity characteristics of the air traffic situation can be comprehensively described; besides, the fund occupation is low, the assessment method is simple and easy to implement, and the assessment result is easy to understand.

Description

technical field [0001] The invention belongs to the technical field of air traffic management, in particular to a method for measuring the complexity of air traffic based on a double-layer multi-level network model. Background technique [0002] In aviation, a flight conflict occurs when two aircraft come too close to each other for less than separation criteria. The central task of air traffic management is to ensure sufficient separation between aircraft to avoid flight conflicts. However, during the flight of aircraft, their trajectories often cross or overlap each other, resulting in a large number of potential flight conflicts, especially in high-density areas. In order to resolve potential flight conflicts in a timely manner, controllers need to maintain continuous attention to local high-complexity areas and form a relief plan as soon as possible. Therefore, flight conflicts in the air traffic situation greatly affect the workload of controllers, are the bottleneck ...
