Summary
To run rail infrastructure effectively and at a high management level, reliable
information about the tracks must be available. Providing data for this process
requires systematic data collection by means of various monitoring, detection and
measuring systems. With the development of technology, the quality and quantity of
data has changed resulting in large amounts of unused data.
The measurement of rail tracks are not an exception. By increasing measurement
density and the introduction of new data types, contemporary measuring devices
have improved insights into track conditions and behaviour patterns far beyond the
limits that could have been imagined just a few years ago. This has however
introduced new problems with data filtering, over-fitted data, and imbalanced
datasets.
This paper demonstrates how methods of digital signal processing could be
applied to track geometry measurements in order to isolate potential critical track
locations. This method also contributes to an automated process developed by
ARCADIS, an artificial intelligence based decision support system for optimal track
management database.
