Study On The Optimization Method Of Corridor Network With Meteorological Factors

As the operation capacity of trunk routes network is becoming saturated,which has been difficult to meet the continuous rapid growth of air traffic demand,resulting in airspace congestion,flight delays and potential accidents.Besides,air pollution and climate change caused by cruising aircraft gradually attracted people's attention.The tube-shape flow corridor in air traffic management proposes a new class of high-speed airways for the future air transportation system which is constructed of several parallel closely-spaced and high-altitude lanes.On account of the characteristics of large capacity,self-separation,dynamic activation/deactivation,it can increase the airspace capacity,reduce the traffic complexity,congestion and controller workload.This dissertation took the design of efficient and environmentally flow corridors as the core,and carried out research on the optimization of corridors optimization combined with meteorology.Firstly,this dissertation examined the background and the state of the art relevant to flow corridor,especially for the research progress and key technologies related to the concept of operations,and the point-cut was put forward to optimize the corridor;Then the influencing factors needed to be considered in the design of flow corridor were analyzed,and the formation mechanism of contrail and the influence of wind on high-altitude flight level were discussed;Afterwards,a typical route was taken as an example,in order to minimize the total cost of the aircraft flight in the flow corridor,the optimization model of the flow corridor was established in combination with meteorology,and solved based on the genetic algorithm.Subsequently,aiming at flow corridor network applicability in China,from the perspective of traffic,network was designed respectively based on the flight schedule between city pairs and airport clustering method,and the representative indicators were selected for comparative analysis;Finally,the network designed by method of city pairs was designed,the optimization model of the flow corridor network was established in combination with meteorology,and a certain size of the network was selected for experimental verification and results analysis.The example verification shows that the proposed optimization strategy can reduce the flight cost and environmental impact.
