Abstract

The purpose of this study is to evaluate quantitatively the effect of a passage width on choice of egress route at a T-junction. Two experiments were carried out to clarify the behavior of egress under forrowing two conditions. (i) Showing subjects VTR images of T-junction under the limited information of egress route, (ii) Using the simulator system driven by the subjects themselves under the condition that subjects can search for information of egress route freely. From results of the experiment, following two points became clear. (1) Almost 70%〜90% of the evacuees can be led to safety egress without emergency guide lights or emergency guidance, when the relative ratio of the width of the right passage at a T-junction to that of the left one is approximately 1.7〜2.5. (2) There is no difference in choice ratio of a wide passage, in case that relative ratio of the width at a T-junction is over 2.5.
