摘要
为了解决群体疏散连续模型中的多出口选择问题,通过考虑可视范围对行人之间心理作用力的影响,修正社会力模型.引入出口效用函数,从出口客观条件(设计因素和距离因素)以及堵塞效应对行人心理的影响出发,建立基于出口效用评估的多出口选择模型.将该模型与修正后的社会力模型结合,构建多出口选择群体疏散综合模型.利用Microsoft Visual Studio编程软件,实现多出口建筑物内大规模群体运动的有效模拟,验证多出口选择的群体疏散模型的有效性.
Social force model was adjusted by considering the effect on psychological force between pedestrian caused by visual field to resolve the exit selection problem existed in pedestrian evacuation continuous model.Besides,an exit selection model was developed based on the evaluation of exit utility by using exit utility function and starting with objective exit condition,including design and distance factors,and the effect on pedestrian＇s psychology caused by blocking effect.Depending on the adjusted social force model and the exit utility evaluation,a comprehensive exit selection model for pedestrian evacuation was established.Finally,a simulation with Microsoft Visual Studio was performed,which revealed the evacuation＇s characteristic.The results show that the proposed model is valid to simulate pedestrian evacuation.
