Problems solved by technology

There are many existing road network construction methods, all of which select the key elements that affect the network layout as the main line, but do not consider the impact of regional classification characteristics on the network planning and the hierarchical characteristics of the intercity railway network. The results are mostly; while the urban agglomeration is an entity with distinct structural characteristics, which puts forward new requirements for road network planning, and it is necessary to theoretically explore effective and quantitative judgment construction methods

Embodiment Construction

[0053] The present invention will be described in detail below in combination with specific embodiments.

[0054] According to the spatial characteristics of the urban agglomeration, the present invention analyzes the key elements of the construction of the intercity railway network, constructs the network architecture model under the guidance and constraints of the network construction objectives and constraints, and designs the framework process in combination with the evolution law of the network. The selection and classification of lines, the connection and layering of lines, and the optimization and adjustment of networks are used to carry out system design, so as to obtain a line network architecture scheme suitable for the spatial characteristics of urban agglomerations, and can be adjusted according to the classification characteristics of urban agglomerations, providing urban agglomerations The construction of intercity railway network provides powerful quantitative ca...

Abstract

The invention relates to a city group inter-city railway network construction method. The existing railway network construction method does not consider influences on network planning by regional classification features and hierarchy of the inter-city railway network, and qualitative judgment results are in the majority. The method comprises steps: major railway network nodes are selected; key indexes for reflecting importance of the nodes are selected to construct an importance model, importance of the nodes is calculated, and on the basis, hierarchical division is carried out on the nodes by adopting a cluster analysis method; importance of a connection line between nodes is calculated, node pairs which meet comprehensive contact constraint are screened, line connection is carried out sequentially according to construction urgency, and an initial construction scheme is obtained; and a network construction model is build after network perfection and optimization. A method which combines qualitative analysis and quantitative calculation is adopted to systematically analyze key influencing factors for inter-city railway network construction, quantitative processing on the major influencing factors is realized, and scientific accuracy of the construction result is improved.

Description

technical field [0001] The invention belongs to the technical field of rail transit planning, and in particular relates to a construction method of an urban agglomeration intercity railway network. Background technique [0002] The construction of urban agglomeration intercity railway network refers to the construction of hierarchical intercity lines within the spatial scope of the urban agglomeration, connecting scattered spatial nodes, and rationally selecting the route direction according to the geographical location characteristics, that is, trying to use logical supply lines to communicate The transportation demand on the point and surface can realize the balance of transportation supply and demand in space. The structure of the intercity railway network should be coordinated with the spatial distribution characteristics of the urban agglomeration, and should be reasonably connected with the overall development plan of the urban agglomeration and the comprehensive trans...
