Study About the Effect of the Signposting for Evacuation in the Underground Space

Abstract

In this study, the characteristics of evacuation activities from underground areas, under normal conditions and during an earthquake, were investigated in areas around Nagoya station, to calculate the time required to evacuate. An evacuation experiment (along with a questionnaire survey) and evacuation simulation were used, and the effects of signposting were quantitatively evaluated by accurately recording the experiment results and inputting obtained data under a simulation. As a result, basic data related to evacuation from underground areas were obtained, including walking speeds in horizontal and vertical directions, and it was shown that signposting is especially effective when there are a large number of visitors who are not familiar with the area.
