Evacuation Simulation in Underground Sample Clauses

Evacuation Simulation in Underground. “The correct and quick evacuation of occupants is very important for the save of lives in a public building when it is attacked by a fire” think Xxxxx Xxx, Xxx Xxxx, Xxxxxxxx Xxx and Xxxxx Xxx (2005) who made their virtual reality system to simulate evacuation in underground station. Reason, to simulate such as environment is simple, it is dangerous and expensive to do it in real life. Based on real life, the evacuation of the occupants can fail because of two possible reasons: “one is that the emergent evacuation is delayed due to the improper layout of the inner structure of the building; the other one is that occupants take unreasonable evacuation measures because of panic and unfamiliarity with the burning building.” (Xxx, Xxxx, Xxx, Xxx, 2005) To solve first issue, the solution is to simulate emergency evacuation in fire condition during the design process of a building. For the second issue, the solution is to conduct emergency evacuation training and drilling in real building. However, as I have learned from previous articles as well, disadvantage is high cost, poor capacity and easy to cause accidents. They focused their research on development of Virtual Reality technology to make it possible to overcome this disadvantage. In their virtual environment, the users are able to move and to explore virtual fire. They used model FDS (Fire Dynamic Simulator) for fire simulation, they simulated the flames and smoke to make this environment as real as possible. Navigation and interaction, also immersion provided by the system, there are some important issues which were included in this research and used to simulate occupant evacuation in this virtual environment.
