Problems solved by technology

Time error has a serious impact on the accuracy of card swiping site matching and other data mining
[0005] In addition, there is another problem that needs to be solved in card swiping site matching: because the GPS (or Beidou) receiver signal in the GPS (or Beidou) driving record system is affected by the shadow of urban buildings or bad weather, the positioning fails, causing the site The lack of information directly leads to the inability to match the credit card record with the site

Embodiment

[0040] A matching method for IC card swiping stations based on the fusion of public transportation multi-source data, the process is as follows figure 1 and figure 2 shown, including the following steps:

[0041] The first step is to obtain the card swiping record of the bus to be matched in the card swiping system. The card swiping record includes the IC card number and the card swiping time stamp; process the card swiping time stamp to obtain the card swiping time sample set;

[0042] Obtain the station reporting record of the bus to be matched in the GPS driving record system, and the station reporting record includes the station identification code a and the time stamp tj when entering the station a and outbound timestamp tc a ; Respectively obtain the stop time interval of each station identification code [tj a -t margin , tc a +t margin ]; where, t margin The amount of time error allowed by the matching algorithm for the card swiping site; the user can set t by h...

Abstract

The invention provides a public transportation multi-source data fusion based IC card swiping station matching method. The method is characterized in that data resources of a card swiping system and a GPS vehicle movement recording system are fused; and the optimal time lapse amount is obtained based on an adaptive random search algorithm to eliminate the time difference between the card swiping system and the GPS vehicle movement recording system so as to realize IC card swiping station matching. According to the IC card swiping station matching method, equipment regulation and changing is not required, while equipment adding is not required as well; therefore, low computation burden and high computation speed are realized; and the mutual matching between the IC card numbers and card swiping stations can be effectively realized, so that guest flow statistics and data mining can be facilitated.

Description

technical field [0001] The invention relates to the technical field of intelligent public transportation, and more specifically relates to an IC card swiping station matching method based on multi-source data fusion of public transportation. Background technique [0002] In recent years, bus IC cards have been widely used, improving the boarding efficiency and payment convenience of card-holders. With the increase in the number of card-holders, the swiping records of bus IC cards have become a new way to obtain passenger flow information at low cost, and have attracted great attention from domestic and foreign bus researchers. [0003] At present, the more popular applications for card swiping records are: under one or more specified time scales, for a specific line, obtain the passenger flow of boarding, passenger flow of getting off, and OD passenger flow between stations; for For some designated lines, obtain the passenger transfer flow between its stations; for all line...
