Development of a tool allowing the correlation between the subjective comfort felt by trains' passengers and the corresponding physical components

摘要

The Innovative and Research department of SNCF is conducting research projects on global comfort focused on the train passengers' perception of comfort. The objective of these studies is to determine the different components of comfort and define criteria that can predict comfort from physical measurements acquired on trains. The final goal is to propose comfort specifications that can be applied by train's constructors. This paper presents a portable system that has been developed to acquire simultaneously the physical components of comfort (acoustic, climatic, dynamic and lighting) and the continuous feelings of the passengers. Some existing criteria are also discussed and some correlations between subjective and physical measurements are also given as examples.
