Abstract

The invention provides a bus get-on / off site identification and examination method based on multi-source data mining. The method comprises steps that based on IC card swiping and operating vehicle data of conventional buses, IC card swiping passenger get-on site identification based on clustering and correlation analysis is performed; according to the IC card swiping and operating vehicle data ofconventional buses, BRT and subways, IC card swiping passenger travel chain get-off site identification based on the conventional buses, the BRT and the subways are performed; data of unidentified get-off sites is subjected to IC card swiping passenger get-off site identification based on historical ride records; the data of the re-unidentified get-off sites is subjected to IC card swiping passenger get-off site identification based on Bayesian posterior maximum likelihood estimation; the data of the matched get-on site is subjected to IC card swiping passenger get-on site identification basedon the paired sample t test; the data of the matched get-off site is subjected to IC card swiping passenger get-off site identification based on transfer behavior identification. The method has advantages of wide application scope and high site identification accuracy.

Description

technical field [0001] The invention relates to the field of bus information data processing, in particular to a multi-source data mining bus stop identification and inspection method. Background technique [0002] With the upgrading and renewal of public transportation-related technologies and equipment, the popularization of bus card systems, and the increase in the use of IC cards, a large number of passenger IC card swiping data and satellite positioning information data provide feasibility for the analysis of public transportation data. Based on the complete travel data of passengers obtained from multi-source data mining of passenger IC card swiping data, the OD matrix of public transport passengers can be quickly and dynamically obtained, and these OD matrices can be used for bus route adjustment and network optimization, The design of connecting lines, research on transfer policies, and passenger flow characteristics (passenger flow corridors, distribution centers, p...
