OD-based rail transit station passenger flow structure similarity analysis method and device

Abstract

The invention discloses an OD-based rail transit station passenger flow structure similarity analysis method and device. The method comprises the steps of: constructing a proportion matrix according to the historical passenger flow data of a station, and calculating a covariance matrix; calculating Euclidean distance matrixes between the proportional matrixes of a workday and a reference day, between transposing of the proportional matrixes and between the covariance matrixes; and constructing a time and station weight matrix, calculating similarity values of a proportion matrix, a proportionmatrix transposition and a covariance matrix, finally calculating a total similarity value, and analyzing passenger flow structure similarity according to the total similarity value. According to theinvention, structural similarity analysis of the station is carried out, the passenger flow similarity of different workdays is studied from the aspects of total daily passenger flow and fluctuation,the similarity of the same station on different dates is further analyzed from the aspect of the daily passenger flow structure, namely the passenger flow destination, good accuracy, openness, ductility and self-adaptability are achieved, the time granularity and weight are dynamically corrected according to the actual situation, and passenger flow structure similarity analysis is more accurate.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to an OD rail transit station passenger flow structure similarity analysis method and device. Background technique [0002] Urban rail transit plays an important role in urban passenger flow transportation services. With the acceleration of urbanization in my country, people's daily travel needs increase rapidly, resulting in increasingly prominent ground traffic congestion, which seriously affects people's lives. When ground transportation is facing serious challenges, rail transportation has gradually come into people's sight with its characteristics of fast, safe, efficient, convenient and large capacity. Rail transit does not occupy ground space and can meet people's daily travel needs. It is the main public transportation mode in large cities to share the passenger flow of ground buses. [0003] More and more residents choose to travel by rail transit, the temporal ...

Problems solved by technology

The similarity analysis of rail transit passenger flow plays an important supporting role in the process of rail transit operation, management and control, but there are still problems in the current research on the similarity of passenger flow of rail transit stations, which is mainly reflected in the problem of the single dimension of analysis, which is mainly reflected in the The research on the similarity analysis method of station passenger flow direction is not deep enough, it is difficult to accurately describe the structural similarity of passenger flow at each station
