Time Constraints in Emergencies Affecting the Use of Information Signs in Wayfinding Behavior

The purpose of this study is to understand how time constraints affect users’ wayfinding behavior corresponding to information signs. Experiments on subjects with non-wandering priority wayfinding with time constraints and wandering priority wayfinding without any time constraints were conducted to simulate the actual situation of people in above-ground and under-ground spaces. Results showed that directional signs are used to help the users follow instructions and to direct people to move straight ahead. Orientation signs like maps force the users to memorize the information and confirm the destination shown on them.
