摘要:
为研究小群体行为作用对地铁站突发事件人群疏散效率的影响,基于社会力模型理论和智能体技术,构建地铁站人群疏散模型。分析小群体趋向性、协调一致性等行为特征,运用社会力模型理论,计算小群体成员移动速度;量化小群体行为对群体内部成员作用大小,修正成员期望速度,确定人群疏散速度;以某地铁站火灾事故为例,分别模拟单人疏散场景和混合疏散场景。研究结果表明:混合疏散场景仿真时间比单人疏散场景仿真时间延长12.29%,平均绕行距离比单人疏散增加38.8%,小群体行为降低了地铁站突发事件人群疏散效率。
Abstract:
In order to study the influence of small group behavior on the efficiency of crowd evacuation in the emergency of subway station, a crowd evacuation model of subway station was built based on the social force model theory and the agent technology. The behavioral characteristics of small group were analyzed, such as the tropism and consistency, then the movement speeds of small group members were calculated by using the social force model theory. The action size of small group behavior on the internal members of group were quantified, and the expected speeds of the members were corrected, then the evacuation speed of the crowd was determined. Taking the fire accident in a subway station as an example, a single evacuation scene and a mixed evacuation scene were simulated respectively. The results showed that the simulation time of the mixed evacuation scene was 12.29% longer than that of the single evacuation scene, and the average detour distance was 38.8% higher than that of the single evacuation scene, so the small group behavior reduced the efficiency of crowd evacuation in the emergency of subway station.
