某商品大集人员疏散的仿真模拟研究

目前，在各地均有商贸活动开展，且参与人员众多，如果公安机关事先未做好预案，一旦发生突发性事件，人员疏散不到位，极易造成群死群伤事件。文章以商品大集为例，构建参与人员的流动模型，利用计算机技术实现流量和流动状况的模拟仿真，获得接近实际的流动的时间和动态过程．利于事先对类似活动拥堵情况进行准确评估。

Researches on the Pedestrian Evacuation Simulation and Emulation in the Trade Mall

A lot of business activities have launched everywhere now, so many people have participate in. If there is any accident of trampling happening in the dispersing crowds, the result will inevitably be very serious. It requires the police offices to make the reserve plan first. The model of the persons movement is building in this paper and take the trade mall as an example.We can use computer technology to simulate the pedestrian evacuation, then achieve the evacuation time and dynamic process. This will help the police offices make accurate assessment of the congestion of similar activities.
