Research Of Airport Surface Taxiing Performance Based On Multiphase Flow

Airport is an important hub of the aviation transportation system. In recent years, with the surge in the volume of air transport business, the demand contradiction of airspace route and the ground terminal capacity have become increasingly prominent. The main airport in the world have suffered different degrees of saturation, also leads to the airport flight delays,congestion and cause huge economic losses. The deduction, calculation and evaluation of operation situation of airport scene traffic, and take effective measures to improve the operation efficiency, reduce the flight delay has become a research hotspot, This paper provide a theoretical basis for the construction of airport and improve the operation efficiency of the control by analyzed and evaluated the airport taxiing performance.First introduced the traffic flow theory, the application of the theory of cellular automata model and multi agent theory in traffic flow research were analyzed, and taxiing mechanism of airport scenes were analyzed. Then proposed the method of the study of airport surface taxiing based on the theory of multiphase flow. The theory of multi Agent intelligent body theory and cellular automaton model are combined as the construction method of airport scene traffic simulation model, different parts of the airport traffic are defined as a one-dimensional cellular automaton, Aircraft Agent and Tower Agent structure are defined,an airport surface traffic simulation model of multi Agent-Cellular Automaton is constructed based on a actual airport parameters; through the simulation of airport scene traffic, the theory of multi-phase flow as the analysis and evaluation method, the aircraft taxiing speed, aircraft taxiing time, waiting time, the pavement load density, airport traffic flow as the main performance index of airport surface traffic flow. According to the different relationship of the performance, the traffic flow is divided into free flow, synchronized flow and wide moving jams. By analyzing the relationship between different performance index and the the evolution of the intersection relationship of flow in different situations, the research on the performance of the airport taxi is realized.Simulation results show that the proposed research method is feasible and efficient, and the simulation of airport surface traffic is realistic, the airport scene traffic situation can bededucted, calculated and evaluated. It has a high application value to improve the evaluation of construction projects on the airport and the airport operation control efficiency.
