| Summary | The smart card fare collection system currently used in Taiwan according to one or two sections, but the one-section system only record the boarding transactions (“tap-in”) and not the alighting transactions (“tap-out”) in the system. This results in many restrictions in the analysis of related applications. Moreover, past studies have yet to show estimation algorithms that make use of the smart card fare information linked with external heterogeneous data. In this paper, we make use of the one-section smart card fare tallying record, combined with the smart card records and regional zoning information, in order to establish a three-stage trip algorithm to estimate the destinations. Tests are performed on a highway bus route, an urban bus route and the whole city bus routes in a county in northern Taiwan. The data from a highway bus route and an urban bus route record the complete two-section ticket tallying information. Estimation was carried out after the “tap-out” data from the smart card information had been hidden. Results indicated that the estimation rates for both routes were 100% and the accuracy rate was 81.4% and 75.3% respectively. On the other hand, the data from a county in northern Taiwan was then used for the estimation of destinations and shows the 100% estimation rate. Besides, compared with the predict-trip volume data (O-D table) from the MOTC in Taiwan, the gap of the trip number estimation for weekdays and weekends had only 6.47% and 12.78% respectively. Results show that the proposed three-stage algorithm would be useful references for the review in timetable setting and bus routing/scheduling in the future. |
