Small and medium-sized airport site selection and layout method under comprehensive traffic and transportation system

Abstract

The invention provides a small and medium airport site selection and layout method under a comprehensive traffic and transportation system, which comprises the following steps of: defining a multi-airport system region boundary, then establishing a traffic correlation degree model, and carrying out traffic region division on a multi-airport system region; establishing a passenger flow index system, performing reduction on the passenger flow index system, then constructing a neural network model, and predicting the total outward travel amount of each traffic area; introducing a foreground theory, using a Bayesian network to correct a traditional discrete selection model to obtain a civil aviation travel sharing rate; constructing a node importance index system for the nodes of the traffic transportation network based on the airports of the multi-airport system area; and after fuzzy mathematics and clustering analysis are introduced, obtaining an alternative scheme set of the airport site through screening, and establishing an airport layout mathematical model based on the alternative scheme set and the civil aviation travel passenger flow volume to obtain the optimal site selection of the airport. According to the method, based on competition and coordination among airports in a multi-airport system and competition and coordination between civil aviation and other transportation modes, site selection and layout of small and medium-sized airports are achieved.

Description

technical field [0001] The invention belongs to the cross technical field of transportation and airport location selection, and in particular relates to a method for location selection and layout of small and medium-sized airports under an integrated transportation system. Background technique [0002] Airport site selection and layout, as the preliminary work of airport construction, is an important part of airport planning and construction. It involves many factors and is a highly comprehensive multi-objective optimization decision-making problem. With the increase of the number of airports in the multi-airport system area, multiple airports, expressways, and high-speed railways share the external transportation of the area, and the competition between multiple airports in the area and between civil aviation and other modes of transportation is intensifying. [0003] At present, domestic research on airport location problems can be roughly divided into four categories, nam...

AI Technical Summary

Problems solved by technology

[0005] To sum up, the traditional airport site selection mostly starts with a single newly-built airport, with insufficient consideration of other airports and other transportation modes in the entire multi-airport system area, insufficient attention to the travel needs of passengers, and little consideration of various aspects of the multi-airport area. Competition and coordination between airports, civil aviation and other modes of transportation lead to unreasonable layout of airports, resulting in insufficient airport traffic and operational difficulties
