The Impact Of Multiple Types Of Information On Airport Outbound Passengers' Traffic Mode Selection

The rapid growth of air passenger demand has put forward higher requirements for the expansion of air traffic capacity and operation management of the airport.However,the existing service facilities of the airport are still unable to meet the passenger demand,causing the problem of queuing inside the airport and congestion of surrounding roads.Under this background,how to optimize the airport information guidance system and guide passengers to choose a lower cost transportation mode to improve the efficiency of the system has become an important research topic.Understanding the travel decision rules of travelers under the influence of traffic information is of great significance for better designing and improving the traffic information service system.Passengers can get different types of information from various channels in the process of travel,but there is no research on the impact of travel information on passengers' mode of transportation transfer in the process of travel.The existing research can not integrate different types of travel information data obtained in different periods of time.This paper studies the impact of multiple types of travel information on the choice of airport outbound passengers' modes of transportation.The main contents are as follows:(1)The theoretical basis of airport outbound passenger mode selection under the condition of multiple types of travel information is clarified.Firstly,based on the existing research,this paper summarizes the influencing factors of passenger's choice of transportation mode,and analyzes from four aspects: passenger's personal socio-economic characteristics,travel characteristics,travel mode characteristics and external environmental conditions.Then,several used discrete selection models are introduced and the advantages and disadvantages of the models are described.On this basis,the paper puts forward the mechanism of the impact of multiple types of travel information on airport outbound passengers.(2)A traffic mode selection model based on single user is constructed under the condition of multiple types of travel information.Firstly,the modeling idea of airport outbound passenger mode selection under the condition of multiple types of travel information is proposed by analyzing the process of passenger mode selection under the condition of VMS information.Then,the passenger travel cost function is established,and the Mixed-Logit model is used to build the passenger preliminary mode selection model.Finally,considering the impact of VMS information on passengers,thepassenger mode transfer model is established,and the sharing rate of each mode is calculated according to the conditional probability formula.(3)In this paper,a multi-user traffic mode selection model based on multi-user travel information is constructed.Due to the different sensitivity of different types of passengers to time and cost,in order to improve the accuracy of prediction,based on the existing research results,the airport outbound passengers are subdivided into market segments,and a multi-user hybrid balanced allocation model is established under the condition of multi-user travel information.(4)This paper designs an algorithm to solve the model of airport outbound passenger traffic mode selection under the condition of multiple types of travel information to verify the validity of the model and predict the impact of travel information on the traffic mode sharing rate.Firstly,based on the field survey and the existing research results,the parameters of the example are assigned.According to the sensitivity analysis of passenger perception parameters and market penetration,it is found that the combination of waiting time information and road congestion time information can effectively improve the public transport utilization rate and system operation efficiency.When the information quality is high enough,the public transport utilization rate can be increased by 5.3%,and the system operation time can be reduced by 9.9%.Then the analysis of passenger mode selection in different scenarios shows that the more serious the road congestion is,the more obvious the role of road congestion information is.Finally,by studying the choice of different types of passengers,it is found that waiting time and congestion time information have the greatest impact on the passengers carrying large luggage in business travel,which makes the public transport share rate increase by 7.02% and the total travel time reduce by 0.45%.
