摘要
The purpose of this pilot research is to conduct a virtual-reality-(VR)-based feasibility study of evacuation time compared to traditional calculation method for evacuation planning in Japan and Taiwan. The difference between traditional assumptions and VR test results of occupant evacuation is compared. The study shows that most of the subjects tested, as occupants, choose different exits from the ones pre-assumed in the space zoning stage. A significant difference exists between the result derived from traditional calculation method and VR simulation. The function used to calculate evacuation time seems to be effective only when egress signs work properly. Very few subjects choose the shortest egress route as expected, although zoning-based calculation may conclude that a building is secure based on tolerable evacuation time. The route indicated by evacuation signs is not necessarily the shortest one. A case associated with four scenarios is simulated and tested. The result reflects the importance of layout in the planning strategy applied in zoning and egress routes due to building fire. (C) 2000 Elsevier Science Ltd. All rights reserved.
