摘要
通过分析已有的元胞自动机理论基础,改进了从众吸引力算法,简化了复杂空间欧氏距离算法,真实反映了人员惊慌状态下的从众心理,并且提高了危险排斥力和出口吸引力的量化效率.本文重点研究了疏散人群密度、出口宽度、从众心理对疏散时间的影响.研究结果表明,行人疏散时间随行人数量呈线性增加;随安全出口宽度呈负指数性减少;盲目从众导致人群疏散效率降低形成局部拥堵.
By analyzing the basic theory of CA and improving the algorithm of occupant psychology, we simplify the complex algorithm of Euclid space distance, which reflect the occupant psychology of crowds and improve the quality efficiency of the rejection of dangers and the appealing of the exits. This paper mainly studies the effect of the density of crowds, the width of the exits, the occupant psychology of the crowds. The results show that the evacuation time grows linearly with the amount of the crowds, and decreases in negative exponent with the width of the exits. Follow the crowds blindly will cause congestion because the low efficiency of evacuation.
