Research On The Effect Of Runway-taxiway Configuration On Airport Ground Capacity

Due to the rapid development of air transportation industry in China in recent years,the airport,the task of transportation in airport is becoming more and more heavy.Whether a large number of aircraft can operate safely and efficiently in the flight zone with limited land resources has gradually become the focus of social attention.Many airports want to improve the capacity of the ground for reconstruction on the ground,but limited by many factors,like economic factors,airport site,the airport can not be further expanded,so the further development of the need to study how to enhance the airport ground capacity.The simplest way to enlarge airport ground capacity is to add new runway,but it is not suitable for most airports with small traffic volume because of the large investment cycle of new runway,or the geographical environment of some airports leads to difficulties in the construction of new runway,or because the number of flights can not reach the expected planning,and the new runway will lead to surplus capacity and waste of investment after the construction of new runway.Airport expansion,therefore,the ground capacity planning is the most applicable method runway taxiway system,analyzes the applicability of the existing runway taxiway system,adjust the runway-taxiway configuration to improve the runway efficiency.This paper mainly studies the runway-taxiway configuration of the single runway airport.By establishing the model of numerical calculation、example analysis and simulation verification,the suitable runway-taxiway configuration scheme and application strategy are proposed to meet the development demand of the ground capacity of an airport.Firstly,the composition and influencing factors of the airport ground capacity are analyzed,and the factors with the highest correlation with the airport ground capacity are obtained by using the grey system theory and analyzed.Secondly,structural the runway-taxiway capacity calculation model,including the landing capacity model,the take-off capacity model and the mixed capacity model.Then,according to the runway-taxi way system of all domestic airports,the two most runway-taxiway configuration are selected as the most representative.The airport ground capacity is calculated according to the established model,and the corresponding use strategies are given considering the non-full runway take-off mode.Then the established model theory into the instance analysis,with a certain airport as an example,from the airport running taxiway system development process capacity analysis,get the change relationship between the number of the runway-taxiway configuration setting and airport ground capacity,then provide advice on the future expansion of the airport runway taxiway system,in the airport,for example,for two classes runway-taxi way configuration through the analysis to the export taxiway position setting capacity range,airport side can be run according to the peak hour capacity requirements runway-taxiway configuration Settings,thus obtained the airport runway-taxiway configuration setting and usage strategy.Finally,simulation verification is carried out,and software such as AnyLogic is used to further simulate the use strategy of the runway-taxiway configuration of the airport to verify its rationality.
