Setting Conditions of Signs in Escape Routes by Configuration Factor

In Japan, there are many signs unrelated to safety and evacuation in buildings, because of insufficient regulation on advertisement placement. We comprehended the effects of setting conditions of signs on evacuee's ability to distinguish needed information.. We measured the amount of sign's information represented by configuration factor in the visual field with 1.0 m interval. In the results, the value of configuration factor of advertisements was greater than the others, and the one of evacuation guidance was extremely limited. We also examined the difference of results among interval levels and found out that the results with 5.0m interval could be treated almost the same as the one with 1.0m interval.
