Basic Analysis of Whiteout Occurrence Trends for Commercial Vehicle Measurement Data Using Track Measuring Device with Inertial Mid-chord Offset Method

Abstract

Track measuring device with inertial mid-chord offset method is designed to measure rail position by irradiating a laser beam onto the rails, but measured data may not always be used as inspection data due to “whiteout” caused by rail discontinuity in turnouts or weather conditions such as raindrops. In this study, we made a basic analysis of weather-related whiteout in commercial train measurement data using track measuring device with inertial mid-chord offset method, with the aim of efficiently and appropriately selecting data that can be used for practical purposes from frequent track measurement data.
