| Abstract |
Exit sign can help guide evacuees from a hazardous area, for instance fires, to a safe area. Legible exit signs would convey information
about correct way-finding to the evacuees and would lead evacuees to a safe area rapidly so that Required Safe Egress Time (RSET) would
be reduced considerably. In this study, the visibility and legibility of 13 pictograms combining running man-shaped graphic symbols, arrows
and letters were measured to derive effective design of exit signs. Visibility and legibility were quantified based on the participant’s
pre-evacuation time to exit sign. Based on the experimental results, a composition of pictograms that can minimize pre-evacuation time was
derived. As a result, it was measured that the pre-evacuation time of the pictogram using only the running man graphic symbol alone was
the shortest. This is the current pictogram most widely used as a sign to guide the location of emergency exit in South Korea. The results
of this study can be used as an engineering basis for the domestic standards for pictogram design for exit signs. |
