Node Importance Analysis Of Rapid Railway Passenger Network

In the forming condition of basic structure of fast passenger transport network of China railway, the future of China’s railway passenger transport demand, studying related key technology of transport planning and the passenger transportation product persistent planning mechanism, improving the management level of railway passenger transportation, has the important practical significance. Among them, analysis of fast passenger transport network node attributes covering the station will be the development and optimization content of the scheme of passenger organization.There are rich accumulations in high-speed railway transportation product planning and design abroad, they can be used as the planning of our country railway transportation product reference, but due to differences in national conditions and road conditions, according to the specific situation of selective absorption. The technical point of the research results, can be used as a research reference.This paper analyzed the influence factors of passenger node important degree, not only carries on the analysis from the factors of node traffic, road network structure, passenger node technology operating conditions, political and economic influence, also introduces the importance of nodes in the graph theory method of railway, which is less applicated. Not only the number of station connection side of the calculation, and operating frequency station connected edges obtained by optimization design mathematical model, through the operation frequency values of field importance, combined with the station of city node level, comprehensive station node important degree are calculated.Secondly, this paper study the method of node important degree, including principal component analysis, AHP and cluster analysis of comprehensive index as the representative of the rating method in graph theory, and the calculation method of the point, this paper also design importance calculation model of transportation network edge.Finally, used fast passenger railway network in2015as an example, calculated the node of city class node important degree and the important degree of stations.
