摘要
对Helbing提出的社会力模型进行了改进,加入了重叠消除问题的研究,加入此过程后可以有效消除行人间的重叠问题;使用综合考虑到出口距离及出口人员密度的概率选择模型来确定出口,从而解决了按原模型仿真可能出现的各出口人员公布不均的问题,使仿真结果更符合实际。
The paper modifies the social force model（SFM）,proposed by Helbing,and effectively eliminates the overlapping of pedestrians by adding an elimination process.Also,the paper considers the issue of exit selection when multiple exist are possible.It uses an probability model which integrates the distance-to-exit and the pedestrian density into the selection.Thus the problem of distribution unbalance among different exits,rendering the results more relevant to reality.
