Title:
MULTI-SCALE AGGREGATION MODE ANALYSIS METHOD FOR COMPLEX TRAFFIC NETWORK
Document Type and Number:
WIPO Patent Application WO/2023/131215
Kind Code:
A1
Abstract:
The present invention belongs to the field of highway traffic networks. Provided is a multi-scale aggregation mode analysis method for a complex traffic network. The method comprises: firstly, calculating an adjacent matrix, a position attribute matrix, a distance weight matrix, a road grade matrix and a time-phased traffic congestion degree matrix of a highway traffic network; secondly, adding a road network weight influence factor on the basis of a PageRank algorithm, so as to determine a critical node sorting condition; and finally, drawing a two-dimensional decision diagram by means of two indexes including the critical node sorting condition and the shortest path distance, determining a spectral clustering center point and the number of clusters, and adding a position weight matrix, a distance weight matrix, a road grade weight matrix and a dynamic traffic congestion degree weight matrix on the basis of a similarity matrix in spectral clustering, so as to obtain a new weighted matrix conforming to actual road network conditions, and then performing clustering analysis to obtain a road network aggregation block. By means of the present invention, block aggregation characteristics crossing administrative division of a highway traffic network can be analyzed, thereby providing a decision reference for traffic planning, design, conservation and maintenance work, etc.
