Embodiment Construction

[0034] The airport conflict hotspot identification method reads the historical data of the surface surveillance radar, processes the discrete point traces into time-ordered aircraft trajectories, and analyzes the dynamic changes of the passing aircraft speed, position and heading with the taxiway component as a unit. If there is an aircraft that satisfies the conditions for generating a hotspot in the set of aircraft passing the same taxiway, it will be identified as an airport hotspot. Specific steps are as follows:

[0035] Step 1: Generate aircraft track set TRACK={track according to airport surface surveillance radar data 1 , track 2 ..., track n}, where the call sign of the aircraft p that generates the aircraft track track and the time of first appearance of the aircraft T start and the aircraft trajectory track includes a track point set TR and a taxiway set TL; the track point set TR includes all track points passed by the aircraft p, and each track point tr include...

Abstract

The invention discloses an airport conflict hotspot identifying method, which comprises the steps of reading and preprocessing scene surveillance radar data, extracting historical taxiing tracks of aircrafts, calculating a set of passing aircrafts by taking a taxiway component as a unit, analyzing whether overlapped taxiing routes and taxiing time exist between the aircrafts, and whether courses and distances between the aircrafts exceed predetermined threshold values, and identifying the aircraft that satisfies a hotspot generating condition in the set of aircrafts passing through a same taxiway as an airport hotspot. The airport conflict hotspot identifying method disclosed by the invention has the beneficial effects that the method, which is not based on historical unsafe event or potential accident data, is simple to acquire scene surveillance data, relatively low in expert participation degree, direct in airport hotspot identifying process and clear in result.

Description

technical field [0001] The invention relates to the technical field of aviation ground operation safety, in particular to a method for identifying hotspots of airport conflicts. Background technique [0002] With the continuous growth of the demand for air transport of our country's citizens, the flight traffic is increasing day by day, and the runway infrastructure is not perfect enough to meet the current demand for air transport. At the same time, the maneuvering area of ​​large and medium-sized airports is getting bigger and bigger, taxiways and runways are getting more and more complicated, and there are more and more intersections. It is not uncommon for unsafe accidents to occur when aircraft operate in dangerous areas. At some contact nodes in the maneuvering area of ​​the airport, due to factors such as unreasonable track layout, improper identification signs or lighting settings, it is easy to cause doubts to the crew, resulting in wrong skids or other confusion; t...
