Studies have shown that term “ride comfort” has been used as an all-encompassing term for the KTX passengers’ over all experience on the trains. While the KTX train is based on the French TGV model, it is considered to be more comfortable. The passengers’ overall experience with regards to over-all ride comfort has been looked at as a combination of their physical health and emotional state. Fares were not included in the aforementioned questionnaires on ride comfort as there were variations in pricing due to seat arrangement, as well as weekday/weekend rates.
