In this study, we wanted to find out effect of walking characteristics of crowd evacuating through stairs on rotation direction at stair landing. This is to investigate change of walking speed according to change of crowd density. The study was carried out through evacuation experiments, and a total of 20 participants participated in experiment. The results of this study are as follows: First, rotation direction did not affect walking speed of crowd passing through stairs. Second, regardless of rotation direction, walking speed increased as crowd density increased at stair landing. In general, walking speed decreased as crowd density increased, but walking speed increased as crowd density increased in stair landing. Walking speed increased by about 0.023 m/s for every 0.1 person/m2 increase in crowd density during down-left turn, about 0.022 m/s for every 0.1 person/m2 increase in crowd density during down-right turn, and about 0.018 m/s for every 0.1 person/m2 increase in crowd density during up-left turn. The results of up-right turn were excluded because the data were not significant.
