航站楼出发厅小团体旅客应急疏散仿真研究

航站楼出发厅旅客通常以小团体的形式结伴出行，其疏散行为有别于单独旅客的疏散行为。分析小团体旅客的行为特征，从期望速度和小团体内部作用力对于社会力模型改进；针对疏散过程，建立多智能体技术的疏散仿真模型，以某航站楼出发厅为例，模拟不同比率不同区域小团体旅客疏散场景。结果显示，随着小团体旅客比率的增加，整体区域的疏散时间和平均绕行距离也在增加，休息区相较商业区旅客疏散时间更长。

Simulation Study on Emergency Evacuation of Small Group Passengers in Terminal Departure Hall

Passengers in the departure hall of a terminal usually travel in small groups, and their evacuation behavior is different from that of individual passengers. To analyze the behavioral characteristics of small groups of passengers, the social force model from the expected speed and the internal force of small groups were improved; for the evacuation process,a multi-intelligent body technology evacuation simulation model was established, and the evacuation scenarios of small groups of passengers in different areas was simulated with different ratios in the departure lounge of a certain terminal as an example.The results show that with the increase of the ratio of small group passengers, the evacuation time and average detour distance in the whole area are also increasing, and the evacuation time in the rest area is longer than that in the commercial area
