Study On Crowd Evacuation Simulation System

The frequent turning up of high buildings, such as shopping malls, large entertainment places and large-scale stadium due to development of economy and society has satisfied multiple material and mental requirements of people, nevertheless these high buildings also posed safety threats. Once the emergent events occurred in such places, frightened people how efficient and rapid evacuation to be a worthy of further study.The behavior evacuation crowd depends greatly on the interactions among crowd members and many other factors. So, it is very difficult to formulate it. On the other hand, the number of people must be evacuated is usually very high in emergent situation. It is impossible to do experiment like that due to the great expenditure and the possibility of accidents. So, the main feasible tool can be used to study evacuation dynamics is computer simulation.This paper presents a crowd modeling method based on Agent.This method is different from traditional methods,the traditional modeling unit is a group of people,this paper is based on an individual as the unit.This modeling method can very good show the characteristics of individual and group. The model of the perception module that can sense the static and dynamic obstacles in the surrounding environment can achieve very good obstacle avoidance capabilities. After the crowd modeling is introduced, this paper presents the architecture based on the OGRE 3D graphics engine, which is independently developed by us.Based on the 3D engine, we developed a group behavior simulation module subsystem in the form of plug-in.
