利用基于元胞自动机的计算机模拟技术对某大型公园人员疏散进行了案例研究。通过调研分析了该公园的客流量及游客游览特征,结合人员疏散软件对公园进行建模,构成了疏散的拓扑结构,利用此模型对人员紧急情况下的疏散过程进行了模拟,得到了疏散速率随时间变化规律。综合考虑公园出口的游客使用情况、人员流量及游客游览特征等的影响因素,模拟了疏散出口的熟悉度、人员容量和分区疏散3种情况下的人员疏散过程,获得了不同条件下的人员疏散状态,找到了人员疏散影响因素。
A case study was conducted on the evacuation of a large park using computer simulation based on cellular automaton. Through the investigation and analysis of the park’s traffic and tourist characteristics, combined with personnel evacuation software to park the park, constitute the evacuation of the topological structure, the use of this model to evacuate people in emergency simulation process, evacuation rate Varies with time. Taking into account the influencing factors of tourists ’use of the park exit, the flow of tourists and the characteristics of tourists’ excursions, the evacuation process of exit evacuation was simulated under the three conditions of evacuation exit familiarity, staff capacity and district evacuation, and evacuation of evacuation under different conditions Status, find the factors affecting the evacuation of personnel.
