The Conflict Control Theory And Simulation Verification Of The Apron Activity Target

With the rapid growth of airport flights,the aprons have become more busy.Apart from aircraft,the targets on the apron also include a large number of special vehicles and safeguard personnel.In addition,the airport’s non-stop construction activities have led to an increase in the potential conflicts between apron activity targets.This paper mainly studies the conflict control theory of the apron target and carries out simulation verification.Based on the analysis of the composition of the traffic system within the apron,the operating conflicts of the apron are divided and the apron conflict is divided into: launch conflict between gates and taxiing conflict of gates: confrontation conflicts on apron taxiing lines,rear-end conflicts,intersection conflicts,and propose conflict avoidance strategies.At the same time,each area was discretized based on the characteristics of each area in the research apron.Then,the area discretization was modeled in combination with Petri nets.The models for aircraft departure and arrival and launching were respectively established.At the same time,the apron activity conflict control specification is defined.The movement of aircraft in airport scenes is mainly linear and curvilinear motions(turning motions).Based on the analysis of aircraft movements,kinematic modeling of aircraft on aprons,taxiways,and runways is performed.The general kinematics model and the kinematics model of the apron were established respectively;the runway linear kinematics model and the turning kinematics model;the taxiway turning kinematics model.Finally,using Unity3 D and 3DMAX simulation software to complete the three-di mensional modeling of aprons,taxiways,runways,terminal buildings,etc.Considering the aircraft kinematics model and Unity 3D hybrid modeling of aircraft taxiing,the es tablishment of aircraft kinematics activity simulation model.And through the actual sit uation of the Beijing Capital International Airport,a three-dimensional simulation of the aircraft taxiing on the airport scene was conducted to verify the effectiveness of the method given in this paper.
