Abstract
This is the second part of a two-part paper in which a new theoretical approach for predicting motion sickness is experimentally validated by field measurements. In this paper, an extended research activity aimed at the validation of a theoretical model (developed by the authors to evaluate the MSI index) is illustrated. The motion sickness incidence (MSI) index represents the percentage of people that vomit within a certain time interval and was defined to evaluate the passengers| response to low frequency motions. The activity was aimed to a rail scenario and it was conducted together with a well-known company in the railway industry. The rail tests were performed in Slovenia during 2005 (European research project |FACT: Fast and Comfortable Trains|). In the paper, a comparison is made between the results, expressed in terms of MSI values and time histories, obtained from experimental results (subjective measures acquired using questionnaires) and by the authors| theoretical model (starting from experimental objective measures acquired in the form of acceleration time histories).
