Embodiment Construction

[0024] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0025] The invention first abstracts the real aviation network and high-speed rail network into an air-rail coupling network, and then uses a multi-objective optimization method to find the optimal hub node selection scheme. Hub nodes refer to the stations that play the most important role in the overall transportation process of the air-rail coupling network. By increasing investment in these stations, the overall transportation cost can be effectively reduced while ensuring transportation efficiency. The method of the invention starts from the complex network science point of view, can excavate the selection of hub nodes in the air-rail coupling network from a macro perspective, solves the problem of hub node selection, and guides practical applications.

[0026] The principle of the present invention is: the aviation network takes the airport as th...

Abstract

The invention provides a method for selecting a hub node of an integrated traffic network, which is used for identifying a hub node that plays a key role in high-speed railway and air traffic. A dataprocessing module and an optimization solution module are arranged in the computer. The optimization solution module comprises a demand distribution module and a scheme evaluation module. The data processing module obtains the city night lighting data, high-speed railway station, airport data and so on, and builds the air-rail coupling network. The optimal solution module obtains the optimal scheme of hub node selection for the air-rail coupling network under the preset number of hub nodes. The demand allocation module allocates the transportation demand to all the city pairs and assigns the transportation demand to the shortest path of the city pairs. The scheme evaluation module calculates the total transportation cost and the total transfer times for all the selected schemes of the hubnodes, and selects the optimal scheme. The network modeling mode of the invention is more in line with reality, accords with the transportation demand between actual medium and big cities, and can simultaneously take into account the reduction of transportation cost and the maintenance of transportation efficiency.

Description

technical field [0001] The present invention relates to the fields of traffic planning and complex networks, and in particular to a method for identifying hub nodes that play a key role in the operation of comprehensive traffic networks. The present invention mainly involves high-speed rail and air traffic. Background technique [0002] With the rapid development of China's air transportation and high-speed rail transportation industry, the number of airports and high-speed rail stations are increasing day by day, and the transportation volume is also increasing, which shortens the distance between cities and effectively reduces the cost of generating transportation. The cost of traveling by air and high-speed rail increasingly important means of transportation. With the vigorous development of the transportation industry, people often use a variety of transportation modes to travel. Under the current situation of comprehensive utilization of various transportation modes, h...
