Özet

Occupant safety is a major concern for a building in case of emergencies such as fire, bomb blast or earthquake. In such emergency situations, a quick and jam-free evacuation of pedestrian trapped in a network of corridors in buildings is most important. In this paper, we compared the throughputs for two different restrictions on the flow direction with the unrestricted flow for a facility. In this facility, occupants need to go through some source corridors which consists of multiple sources and from source corridors they can choose their nearest exiting corridors. The result indicates that in emergency situation a restricted flow direction of pedestrian increases the throughput of the network which eventually decreases the average evacuation time. © 2013 Asian Network for Scientific Information.
