Analysis of Evacuation Route Selection Pattern of Occupant according to Installation Type of Exit Light and Opening/Closing Direction of Door

Abstract

The purpose of this study is to examine the influence of occupant's path selection on the shape of the pictogram and the opening/closing of the door. This study was carried out through a simulation experiment using computer virtual reality. Exit light pictogram for exit door and exit light pictogram for passage were arranged for each scenario in type T corridor and type + corridor. The computer graphic was used to carry out the simulation. In addition, we analyzed the response of human behavior according to the two directions (left and right) of exit light pictogram for exit door and the effect of opening direction of doorway. In addition, the change of decision-making according to the presence or absence of exit light pictogram for passage was confirmed. The results of the direction selection response were as follows. First, in the case of the T-shaped corridor, if the exit light was not installed on the door, it was influenced by the opening direction of the door. Second, when the exit light is attached to the door, the selectivity in the direction that matches the exit light pictogram direction is high. As a result, it was confirmed that the pictogram direction of the exit light influenced the evacuation route selection of the occupants.
