Rapid Evacuation Strategy Research Shopping Malls In A Critical Situation

With the development of urban commercial core area rapidly,urban context such as shopping malls have become urban commercial area are the most active and prosperous places,but behind the prosperity and active also there is a huge security risks.Both at home and abroad in recent years,safety problems abound in large places,these places how to escape quickly in an emergency problem also is a wake-up call for the people.Crowds gathered in place and a crisis occurs,once an accident,the consequence is very serious.Xidan Joy City because in the region and its commercial function,crowds gathered happens quite often and time change,in the event of a crisis,evacuation,become a key problem.But in large area of the existing safety evacuation plan is in accordance with the same formulation mostly evacuation routes,ignoring the premises of the dynamic change of population density,so produced a demand: in emergency cases,due to the dynamic change of population and to develop a fast dynamic change along with the crowd evacuation strategy.If you can consider to crowd the dynamic distribution of quick evacuation strategy,will improve the efficiency of the evacuation time and avoid due to the failure of evacuation strategy result in unnecessary loss,so as to achieve effective management for large shopping mall.How to effectively develop the crowd under the dynamic distribution of quick evacuation strategy,is a subject of research value,this article will try to solve this problem.Through on-the-spot investigation and data analysis,we get a layer of the actual scale map of xidan Joy City field,according to the video monitor get crowd density distribution and estimation,statistical analysis of the factors influencing the evacuation time,a mathematic model of the quick evacuation,crowd density and distribution,according to data manually calculate the fastest evacuation strategy.Simulation model was established,combining the peak crowd scene scale map with anylogic simulation software,simulation manually calculate the rapid evacuation strategy,the evacuation results of contrast,found that taking this prediction method is effective and practical value.
