Embodiment

[0030] A method based on AFC data to infer bus passengers' alighting stations, which analyzes passenger's bus riding behavior through two adjacent bus card swiping records within the same day, and thus infers the The alighting station corresponding to each card swiping record; figure 1 , including the following steps,

[0031] S1. Obtain all AFC data of the bus line network in a certain day. The original data fields include: card number CARDNO, line name LINECODE, license plate number NO, and transaction time TRADETIME; select passenger objects according to CARDNO, and extract the AFC data of the day of the card number, And arrange them in order according to the transaction time TRADETIME;

[0032] Obtain the route and station information of the bus network, the route information includes the route name and the station name within the route, and the station information includes the station location coordinates;

[0033] According to the license plate number NO field in the c...

Abstract

The invention provides a bus passenger getting-off station speculating method based on AFC data. A bus taking behavior of a passenger is analyzed according to two adjacent bus card swiping records ina day, and thus on the premise that getting-off station information lacks, the getting-off station corresponding to a getting-on card swiping record each time is speculated; according to the bus passenger getting-off station speculating method based on AFC data, by temporal thresholds which comprise average bus taking time, the longest waiting time and the longest transfer duration, transferring behaviors of bus passengers are recognized, and thus a whole bus trip chain is analyzed. By a space analyzing method, based on walking time, the most possible getting-off station is recognized in a radiating area of a station, and reliability of a getting-off station speculating result is ensured.

Description

technical field [0001] The invention relates to a method for inferring bus passengers' alighting stations based on AFC data. Background technique [0002] my country's conventional bus system mostly adopts the "one-ticket system" fare model, and its bus IC card data generally does not directly include information on passengers' boarding and alighting stations. In view of this situation, domestic researchers use travel sample survey data, AVL data, etc. as supplementary data for estimation of passenger flow on boarding and alighting at stations, and realize estimation and prediction of passenger flow information at stations by means of data fusion. Among them, the key point of the research is the identification of passenger boarding and alighting stations based on AFC (Auto Fare Collection, automatic bus fare collection system) data; boarding stations are generally determined by matching the time recorded by swiping the card on the bus or GPS; but Due to the lack of card swi...
