Abstract

In order to improve visual appeal of embedded safety evacuation signs, a simulation test of their spatial direction information transmission efficiency was conducted. Influence of their different spatial angles on subjects' choice response time, expected choice conformity and choice confidence was analyzed, and verified through fire drills to get the optimal space angle. Finally, a kind of spatial three-dimensional embedded safety evacuation signs was designed according to research results. The results show that generally the larger the spatial angle is, the larger the visible area there will be, the shorter the choice response time and the higher the expected choice conformity and choice confidence will be. When the angle is 5°, spatial direction information transmission efficiency is the strongest, with the average escape time of participants being the shortest, and proportion of choosing unfamiliar exits increases. The embedded safety evacuation sign with a spatial three-dimensional structure can effectively improve efficiency of fire emergency evacuation. © 2022 China Safety Science Journal.
