灾害避难行为的模拟模型研究(Ⅲ)——双人单房情况的避难模拟

Study on simulation model for escape behavior in disaster (III): situation of two individuals in a single room

研究突发性灾害下的避难行为,有利于提高公众的防灾减灾意识和灾害抵御能力,在当前城市防灾减灾中具有重要的理论和现实意义。利用计算机模拟仿真试验可以多次重复、简单易行的优点,在对现有的计算机仿真模型进行改进的基础上,开展了不可视环境下双人单房任意方向下的灾害避难行为仿真模拟研究。结果表明,在双人单房的情况下,两人分头避难模式优于两人共同避难模式;同时,进一步的扩展模拟还表明,两人在分头避难又相遇后,进行正确交流也是十分有益的,这往往可以缩短发现避难出口的时间。

The simulation of escape behaviors in disaster is helpful to improving the public's ability to reduce the damage. In the escape behaviors research,computer simulation has obvious advantages for its easy operation and repeatability. With the improvement of the current escape behavior simulation model, this paper investigated the escape behaviors of the two individuals, in a single room. The results showed that the time of two individuals respectively escaping is less than that of two individuals′ jointly escaping. Besides, the communications between the two individuals are also beneficial to their successful escape.
