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. © 2022 China Safety Science Journal.
