| Abstract |
Occupants in the residential or office buildings have high awareness of egress routes because they stay in one spot for a long time. However, in large-scale mazy facilities such as subway stations, discount stores, department stores and multiplex, there is a large floating population of unspecific individuals who do not know the egress routes. In this case, occupants cannot precisely recognize egress routes and escape the building rapidly when a emergency situation occurs. For this reason the regulation that evacuation map or video has to be equipped with a mandatory in multi-use facilities have been implemented since August in 2010 but there is lack of the specific grounds why evacuation maps and videos were adopted as egress route instructions yet. In addition, it is required to expand the legal criteria for any use of buildings because the current law is mainly applied to small scale multi-use facilities such as karaoke, not large scale one. In this study, we made a model with complicated routes simulated a large-scale mazy facility and measured 300 occupants' moving routes and evacuation time in order to investigate how to inform exit and egress route to occupants effectively and rapidly so that they do not wander the path in emergency situation like fire in a large-scale mazy facility that many and unspecified crowds spilled into. The egress scenario includes 10 types of egress route instruction which displays evacuation map or video near entrance, places evacuation staff or installs emergency exit sign within a route. As a result, the cases that evacuation guides are placed in each crossroad, or a skilled leader leeds occupants were the best effective ways to communicate evacuation route to occupants. The cases that occupants follow emergency light or sign on the wall or floor is also a positive influence on evacuation time secondarily while the cases used evacuation maps, video or announcements have less effect. |
