Comfort Analysis System

Keolis is a leader in public transportation and oversees tramway lines in Lyon, France. Keolis wanted to install a system to analyze the comfort and dynamic performance of (Citadis) rolling stock in order to optimize service quality to passengers.



Rail transport reliability and availability require preventative detection of faults that can affect all elements of a rail network (e.g., tracks, catenaries, trucks, etc.). Rail transport industry (e.g., users or those working with infrastructure or rolling stock) needs to identify and characterise malfunctions early through symptoms or anomalies detectable using customised on-board systems.
Rolling stock users (tramways, etc.) require solutions for objective comfort measurement and dynamic performance.

Thanks to its expertise in fast, thorough processing of large quantities of data and SignalLAB's data classification module, RMS offers to rail transport industry solutions that compare physical characteristics found in measurements (descriptors) with the presence of faults or malfunctions.


With SignalLAB Railway, users can analyse comfort in accordance with rail standard ISO 2631-1 and estimate the dynamic performance of rolling stock. SignalLAB Railway is compatible with the SignalLAB software suite, which features unique functions to analyse vibration signals.
