Embodiment 1

[0034] The flowchart of the passenger flow estimation method provided by the present invention is as follows: figure 1 As shown, the method first determines the passenger's boarding route and boarding time through the IC card data, and then matches the boarding time with the bus GPS station reporting data to determine the passenger's boarding site.

[0035] After determining the boarding station and boarding route, it is necessary to infer the boarding station. Urban residents' bus travel behavior has the characteristics of continuity, that is, the starting point of the next trip is generally located around the destination of this trip. Therefore, the possible alighting range is delineated according to the subsequent riding information (site, time, route, etc.), and in combination with the current riding information, the alighting site of the bus passenger can be reasonably inferred.

[0036] Such as figure 2 As shown, the core idea of ​​the inference method of the alightin...

Abstract

The invention relates to a method for estimating passenger flow between bus stops based on IC card data. The method determines the passenger's travel route and boarding station according to the IC card data and the bus GPS station report data, and then infers the passenger's alighting station. Obtain the complete OD information of passenger travel, calculate the OD amount according to the complete OD information, redistribute the missing passenger flow at the drop-off site using the site attraction weight, and use the redistributed passenger flow to correct the OD amount of the complete OD information. , and calculate the number of people getting on and off at the station and the passenger capacity between the stations through the corrected OD amount. Compared with the prior art, the passenger flow estimation method provided by the present invention is based on pure data driving, the algorithm has wide applicability and high accuracy, and can intuitively grasp the bus passenger flow and operation and service conditions.

Description

technical field [0001] The invention relates to the field of intelligent public transportation, and more particularly, relates to a method for estimating passenger flow between bus stops based on IC card data. Background technique [0002] Bus passenger flow information is the basis for urban public transport planning and operational decision-making. Timely, accurate and comprehensive grasp of passenger flow information of residents' public transport is the premise and guarantee for scientific and rational decision-making of public transport planning and management. Bus passengers are the basic elements of public transport passenger flow, and the bus IC card database records the relevant information of each bus passenger swiping the card, so it is feasible to mine these information to reflect the technical solution of bus passenger flow. [0003] How to propose a solution to the defects of the existing IC card data recording method, and realize the deduction of bus travel s...
