摘要:

为探究人为攻击事件下引导员引导作用对人员疏散的影响,基于自驱动力的物理学思想,建立攻击者运动行为模型;引入引导员动态引导作用因素,提出引导员最优出口引导策略,构建耦合引导吸引场、静态场和攻击威胁场综合作用的人群疏散动力学元胞自动机模型;基于所构建的模型展开房间场景模拟试验,研究引导员引导作用、攻击者攻击威胁及攻击偏好对人员疏散的影响。结果表明:引导员引导作用有利于提高人群疏散效率并减少人员死亡人数;攻击者攻击威胁程度的升高不利于人员疏散,其延长疏散时间,增加死亡人数;攻击者对行人或引导员的攻击偏好对人员疏散存在影响,攻击者对行人攻击偏好程度越高,行人在空间的滚动行为越明显,疏散效率越低且死亡人数越多。

Abstract:

In order to study the influence of guiding role of evacuation conductor on evacuation of personnel under artificial attacks, the attacker's movement behavior model was established based on physics idea of self-driving force. The dynamic guidance factors of evacuation conductor were introduced, and the evacuation conductor's optimal exit guidance strategy was proposed. A dynamic cellular automata model of crowd evacuation that couples the combined action of the attraction field, the static field and the attack threat field was introduced. Based on constructed model, the room scene simulation experiment was carried out. The results show that guiding role of evacuation conductor is conducive to improving the efficiency of crowd evacuation and reducing the number of deaths. It is also found that increase in the threat of attack by the attacker is not conducive to evacuation, which prolongs the evacuation time and increases the death toll. In addition, the results also show that attack preference has an impact on evacuation of people. The stronger the attacker's preference for pedestrians, the more obvious the rolling behavior of pedestrians in the space, the lower the evacuation efficiency and greater the number of deaths.

Key words: artificial attack, guiding role, pedestrian evacuation, evacuation model, attack preference
