Modeling And Simulation Of Vehicle Behaviors On The Airport Terminal Departure Level Road

In the traffic environment of the roads on the departure level of the airport terminal building,the road environment is intricate,with frequent vehicular and pedestrian movements,causing traffic chaos and congestion,which makes traffic management stressful.In order to address this issue,there is a need to understand the fine-grained behavior of vehicles and the factors and interactions between people,cars and roads that affect vehicles.Fine modeling of vehicle behavior on the departure level of the airport terminal building is an important part of the urban traffic chain,and lays the foundation for the study of vehicle behavior in traffic areas where other roads are complex,traffic objects are mixed and traffic behavior is diverse.Currently,research on traffic vehicle behavior focuses on VMT at intersections,with less research on vehicle stopping behavior and the process of unloading/picking up passengers.In this paper,the following studies were carried out on the traffic environment on the departure level roads of the terminal where frequent stops are made to transport passengers:1.Analysis and modelling of vehicle behaviour under the influence of the road environment.The first refinement analysis of the behavior process of vehicles in the road traffic environment on the departure level of the airport terminal building,the refinement analysis of the type of behavior of vehicles,considering the characteristics of vehicles such as size,speed,time,etc.,to construct and verify the empirical behavior model of vehicles.The information about the elements in the road is then studied,the influence of road elements on vehicle behaviour is analysed and a model of vehicle behaviour that takes into account the car-road relationship is built.2.Construction of a traffic simulation model based on a metacellular automaton.The principle and application of metacellular automatons in traffic are analyzed,and on the basis of the classical model of metacellular automatons method in traffic simulation,vehicles and roads are cut into different metacells based on the empirical behavior model of vehicles and the vehicle behavior model based on the car-road relationship,and then the metacellular automaton-based traffic simulation model is built according to the traffic rules of vehicle behavior to realize the simulation and simulation of vehicle behavior process,and the reasonableness of the model is verified by comparison analysis with the results of statistical analysis.
