Limited airspace unit identification method based on DBSCAN clustering algorithm

Abstract

The invention discloses a limited airspace unit identification method based on a DBSCAN clustering algorithm. The method comprises the following steps: firstly, defining an airspace unit; secondly, collecting actual flight operation data and corresponding air route information, and matching the air route information with longitude and latitude coordinate data of an airspace unit to construct an air route network model; then, calculating flight delay data, downsampling the data, and associating the data with an airspace unit to obtain flight delay feature data; and finally, constructing an identification model of the limited airspace unit based on a DBSCAN clustering algorithm in combination with the airway network model and the flight delay characteristics. The limited airspace unit and the limited starting and ending time can be identified, and randomness caused by severe weather, air traffic control and other events can be solved. The starting time and the ending time of airspace limitation are determined, direct flight delay and delay caused by propagation can be separated, the propagation mechanism of flight delay is further explored, and the method has important significance in improving the accuracy of flight delay prediction.

Description

technical field [0001] The invention relates to a method for identifying a restricted airspace unit based on a DBSCAN clustering algorithm, and belongs to the technical field of air traffic management. Background technique [0002] With the rapid development of civil aviation, flight delays have become an important issue in the air transportation system, and the aviation industry has been suffering economic losses. According to the Bureau of Transportation Statistics (BTS), more than 20 percent of all flights were delayed in 2018. In China, the flight anomaly rate is 80.13%, which means that more than 850,000 flights were delayed in 2018. There are many factors that lead to flight delays in actual operation, such as airline operation management factors, weather factors, air traffic control flow control, military activities, etc. These factors will cause airspace units to be restricted to varying degrees, resulting in flight delays. . At the same time, the emergence and oc...
