Comparison of methods for evaluation of the track geometry quality

Abstract

This paper is aimed at evaluation of the track geometry quality based on data from a measuring car for railway superstructure. The evaluation of the track geometry quality serves as a necessary basis for effective track maintenance planning. In the first part of the paper methods and procedures for assessment of the track geometry quality are described. The second part of the paper deals with track geometry data evaluation using variables such as standard deviation, track quality index and fractal dimension. The last part of the paper is focused on comparison of the variables and summary of results.
