Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0038] Such as Figure 1 to Figure 7 as shown, figure 1 It is a flow chart of the method for calculating the boarding station based on the one-ticket bus IC card data of the present invention. The method for estimating boarding stations based on the one-ticket system bus IC card data includes the following steps: firstly, according to the time of card swiping records, the discrete card swiping transaction records are clustered and analyzed, and the records with similar card swiping times are clustered into a cluster, that is, a group data. Each cluster corresponds to a site, forming a sequence of sites to be identified. The estimation of the boarding station is to obtain the actual station corresponding to each cluster. Since not all boarding stations have people swiping the card to b...

Abstract

The invention discloses a method for reckoning getting-on stops on the basis of data of a one-ticket public-transport integrated circuit (IC) card, comprising the following steps: a, carrying out clustering on card-swiping records of a target bus according to the time of the card-swiping records, taking the time-adjacent card-swiping records as a cluster, each cluster corresponds to one stop, and forming a stop sequence to be recognized; b, determining transfer information according to adjacent card-swiping records of each IC card; c, according to transfer the information, crosspoint data information between bus routes and stop information of the bus routes, reckoning the practical stops corresponding to the cluster of the IC card and forming a recognized stop sequence; d, according to the recognized stop sequence, reckoning a practical stop to be recognized corresponding to a cluster to be recognized, and when the recognized stop quantity is less than 2, reckoning by a Bayesian decision tree method featured by mobile step; and when the recognized cluster quantity is more than or equal to 2, adopting a mode recognition method for reckoning. By utilizing the method, the requirement to data is low and the accuracy is higher.

Description

technical field [0001] The invention relates to the technical field of public transport information processing, in particular to a method for estimating boarding stations based on one-ticket bus IC card data. Background technique [0002] Bus passenger flow information, especially the distribution information of passenger flow in time and space is the data basis for bus planning and decision-making. In the past, bus passenger flow information was mostly obtained by manual surveys, which not only limited the sample size, but also consumed a lot of manpower and material resources. At the same time, the quality of the data was not easy to guarantee because the data went through multiple links such as collection, input, and analysis. With the application and popularization of IC cards in the public transport system, it is possible to process and analyze the data of IC cards and obtain the passenger flow data of urban public transport. Not only is the data volume of bus IC cards...
