In order to develop a comfort evaluation index which represents the degree of comfort level in the passenger room, we performed a questionnaire survey of 2,250 travelers and simultaneously measured physical indices such as vibration and noise on commercial trains. After analyzing the data obtained, we proposed two types of comfort evaluation indices. One is a simple index based on only physical indices and composed of a weighted summation of vibration, noise, illuminance and seat pitch. Its correlation coefficient with passenger's comfort rating is 0.715. Another is a detailed index which adopts physical indices added with railway engineers' subjective evaluation of seating comfort and cleanness of the room. Its correlation coefficient improves to 0.877.
