Estimation of Paratransit Passenger Boarding/Alighting Locations Using Wi-Fi based Monitoring: Results of Field Testing in Krabi City, Thailand

Abstract

The objective of this study is to investigate the applicability of Wi-Fi monitoring technology to the estimation of the boarding and alighting locations of paratransit passengers via a small-scale field test that was conducted in Krabi City, Thailand. From the results, we determined that: (1) with use of appropriate data cleaning procedures, many of the noisy data could be eliminated to a reasonable degree; (2) it would be reasonable to ignore Wi-Fi data for which the moving distances are too short, and regard them as outliers or irrelevant records; (3) when the proposed matching methods are used with the ground truth data, suitable numbers of the Wi-Fi data are well matched.
