Railway Track Quality Assessment Using Topological Data Analysis

Abstract

AbstractThe US railway system requires continuous monitoring to ensure safety and efficiency. Traditional track quality indices (TQI) often fail to detect variations in track geometry, missing critical irregularities that impact safety and ride quality. ...Practical ApplicationsThe topological track index (TTI) provides a practical enhancement to existing railway track monitoring and maintenance practices by capturing spatially structured geometric irregularities that may be underrepresented by conventional ...
