Air traffic situation risk measurement method based on two-layer multistage network model

Abstract

The invention discloses an air traffic situation risk measurement method based on a two-layer multistage network model. The method comprises four steps: firstly, acquiring comprehensive trajectory ofan air traffic control radar or ADS-B trajectory data; acquiring information of an aircraft in an air traffic situation at each moment; secondly calculating a potential conflict relationship of the aircraft in a two-dimensional horizontal direction and a three-dimensional space; establishing a two-layer multistage air traffic situation risk new model; then calculating various statistical indicators in a risk network; and finally forming an air traffic situation risk measurement vector at each moment. The method is an objective assessment method for air traffic situation risks, comprehensivelydepicts two-dimensional structure and three-dimensional structure characteristics of air traffic situation, occupies less capital, and is simple and easy to use, and easily understandable for assessment results.

Description

technical field [0001] The invention relates to the field of air traffic management, in particular to an air traffic situation risk measurement method based on a two-layer multi-level network model. Background technique [0002] A flight conflict occurs when two aircraft come too close to each other for less than the separation criteria. The core task of air traffic management is to ensure that there is sufficient separation between aircraft to avoid flight conflicts. However, during the flight, the trajectories of flights 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-risk areas and form a relief plan as soon as possible. Therefore, the flight conflict in the air traffic situation greatly affects the workload of the controllers, is the bottleneck of the capacity o...
