Trend Analysis of On-board Measured Data Collected Periodically Using Smartphone

Abstract

As part of efforts to support track maintenance work on regional and local railways, a low-cost method of supporting train patrols using smartphones is being developed. In this study, the transition of on-board measured data on a regional railway line, such as train vibration and forward-view image, collected periodically during train patrols using a dedicated smartphone application, was analyzed. It was found that changes in dynamic track conditions can be confirmed from the changes in on-board measured data.
