This study is aiming to compare stair ascent transportation speed and physical burden of evacuation supporters according to the types of stair ascent transportation for vulnerable people experimentally. In this study, we measured heart rate of the supporters to indicate physical burden during the transportation. The subjects of this experiment were male students, age of 18-24. Experimental conditions were the ways of stair transportation and the weight of vulnerable people. The types of stair transportation were giving a piggyback ride, carrying a handy stretcher and carrying a wheelchair. Each experimental trial was video-recorded for measurement of ascent speed and observing supporters movement. As a result, this research proves that the weight of vulnerable people has an impact on the ascent speed and physical burden of supporter and giving a piggyback ride is the fastest in all ways of stair ascent transportation but the physical burden for a supporter is the heaviest.
