Embodiment Construction

[0067] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0068] First, some basic concepts are explained.

[0069] The traffic area division system provided by the present invention reduces the complexity of the traffic system by analyzing the factors of the traffic area division in the urban public transport system. The present invention draws lessons from the complex network theoretical model, takes the urban building group as the smallest division unit, discusses the abstract method of the urban building group network, designs the network structure parameter calculation method, and constructs a complex network with the building group as the node. Based on the network, the traffic attributes Similar building groups are divided into the same traffic area. Before the present invention divides the traffic area, it is ne...

Abstract

A traffic zone partitioning system based on a Louvain algorithm, and the system comprises a building space topological relation judging module, a building group partition road grade calculating module, a building group topology distance calculating module, a complex network edge weight calculating module, a Louvain algorithm executing module and a district partitioning result displaying module. The traffic district partitioning system provided by the invention reduces the complexity of the traffic system by analyzing the factors of the traffic district partitioning in the urban public transport system. The invention takes the urban building group as the smallest partition unit, probes into the abstract method of the urban building group network, designs the calculation method of the network structure parameters, constructs the complex network with the building group as the node, and divides the building group with similar traffic attributes into the same traffic district based on the network. The results of traffic plot division will affect the accuracy of traffic demand analysis and forecasting, which is of great significance to ensuring the feasibility and accuracy of a traffic planning scheme in traffic zone partitioning and optimization.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, in particular to a traffic area division system based on Louvain algorithm. Background technique [0002] Before dividing the traffic area, it is necessary to discretize the urban area and construct the basic geographic unit as the initial clustering unit for the division of the traffic area. The essence of discretization of urban areas is to use a limited number of geographical units to replace continuous urban space, and abstract urban space into a collection of basic geographical units with spatial attributes and spatial relationships. The main forms of basic geographic units include: streets, demographic divisions, administrative districts, and polygonal grids. At present, there are two most widely used discretization units in traffic districts: road network structure and planar objects. [0003] Regional discretization method based on road structure: In this method, the ...
