Research On Airport Landside Traffic Evaluation Based On Accessibility

The airport is an important hub for land transportation and air transportation.At present,due to the gradual improvement of people’s living standards,air transportation has become the first choice for many travelling passengers,which has led to the airport’s large passenger throughput and large number of pedestrian transfers.For passengers,it is not enough to have good flight services.Comfortable and convenient airport land-side transportation services have also become an increasingly important consideration for passengers in recent years.From the perspectives of theoretical analysis,model establishment,and case analysis,this paper uses the combination of theory and examples,qualitative analysis and quantitative analysis to evaluate the airport landside traffic.Relevant research contents and conclusions are as follows(1)According to the research purpose,first analyze and summarize the land-side traffic characteristics of major airports to find out the existing problems of land-side traffic at airports.Accessibility is defined as the ease with which passengers travel from the airport to various destinations in the city based on different traffic resistances in airport landside traffic.This paper systematically analyzes the airport landside traffic time accessibility,economic accessibility,and space accessibility.The influencing factors of airport landside traffic accessibility were analyzed,and the corresponding relationship with the airport landside traffic travel costs was analyzed to provide theoretical support for the subsequent model establishment.(2)The travel cost of airport landside traffic was studied from three aspects: fastness,economy and comfort.The advantages and disadvantages of various accessibility evaluation models were analyzed.Finally,a space barrier model was selected based on the airport landside traffic theory to construct Evaluation model of airport landside traffic based on reachability cost.The accessibility cost is subdivided into time cost,Money cost,comfort cost,and the specific measurement methods of various costs are studied and analyzed.The accessibility cost of land-side traffic at various airports is calculated,and based on the availability of urban residents The accessibility index is obtained by normalizing the dominated monthly income and compared with the domestic airport accessibility index.(3)The feasibility of the model is verified by using Hongqiao Airport’s landside traffic as an example.The research shows that the accessibility cost of Hongqiao Airport’s landside traffic is 84.38 and the reachability index is 61.8.Based on the national airport landside traffic accessibility data as a sample,based on the numerical distribution,the airport landside traffic evaluation level classification criteria were obtained,and the Hongqiao Airport landside traffic was at the "good" level.Competitive analysis of Hongqiao Airport’s landside traffic with Beijing Capital Airport and Guangzhou Baiyun Airport,which are rated as “good” in China.The competitive radar chart shows that Shanghai Hongqiao Airport’s rail transportation,taxi,car and other three modes of transportation There are obvious shortcomings in accessibility.According to the comparative analysis of the reachability data,the main reason for the shortcomings is the insufficient public traffic sharing rate in Hongqiao Airport’s landside traffic,which caused the airport’s landside traffic congestion and increased the time cost.(4)From the aspects of increasing the airport’s land-side traffic volume and improving the airport’s land-side public transport service level,the optimization strategy for the airport’s land-side traffic is proposed.The relevant theories can be extended to railway stations,water transportation ports,bus platforms and other transportation infrastructure.
