A PSYCHOPHYSICAL EVALUATION OF INTERIOR-DESIGN ALTERNATIVES FOR A HIGH-SPEED TRAIN

The magnitude estimation technique was used to evaluate several interi or design alternatives for a high speed train. Design factors consider ed in this study include direction of passenger seats; passenger activ ity; and passenger age. The results showed that the passenger seat sho uld be able to be arranged toward the traveling direction of the train . Also, a variety of convenience facilities could enhance the passenge r comfort. These results were validated by using two different depende nt measures. This paper demonstrates the use of psychophysical measure ment techniques when it is difficult to express subjective preference in the form of quantitative data for making engineering decisions.
