Research And Application Of Emergency Evacuation Simulation Model Based On ABM Modeling

Along with the great development of the human productivity, the human material life gets greatly satisfaction. It makes population doubling time shorter. Population growth pressures our environment,at the same time, also makes the human society facing more and more public security problems, public places of crowd evacuation security problem is one of them. The greater growth of population has made the public building bigger and bigger, so the public building can hold more and more number of people. As we all know, the high number of people within a certain space are very easy to cause accident of crowd evacuation, so more and more scholars began to study of crowd evacuation safety problems. Look from the objective conditions, organize a large number of people to make crowd evacuation experiment, both from an economic, security and utility angle, are not feasible. So the present study of crowd evacuation is through computer simulations to reappear the crowd evacuation of reality. On this background, the previous studiers invent a lot of crowd evacuation simulation models. These models depend on the self-organization phenomena and the individual behavior simulates a series of dynamic characteristics and dynamic rule in the process of crowd evacuation. This paper, on the study of the complexity and complex adaptive system, find the people and the environment constitute the complex adaptive system in the process of crowd evacuation, so we can use some methods of complex adaptive system to study the process of crowd evacuation. The ABM modeling which used to construct the model of complex adaptive system can be used to construct the model of crowd evacuation. In the process of modeling, In the process of modeling, magnetic field and mechanical principle is used to construct the environment information, so we invent a new type of crowd evacuation simulation model:the model of the ABM based on the principle of magnetic field and mechanical. Articles introduce the structure of the model in detail, at the same time; through using the method of single, contrast argument prove the validity of the model. In comparison with the similar model introduces the superiority of the model. Finally we use the model evaluates a large complex public places of Kunming layer3central area evacuation ability and put forward relevant suggestions. These measures gain a certain effect.
