摘要
为了解决密闭空间内密集人群应急疏散效率低下的问题,构建了基于智能引导标志的人群疏散引导模型,提出了基于均衡拥堵策略的指示标志布局优化方法和基于社交网络搜索的指示标志引导权重优化方法,用以提高疏散效率.仿真实验证明:优化后的智能指示标志布局可以有效缓解疏散过程中的局部拥堵,减少行人由拥堵引起的时间消耗;优化后的智能指示标志引导权重可进一步均衡出口利用率,有利于充分利用环境资源,进一步提升人群疏散效率.
Abstract
Aiming at the low emergency evacuation efficiency of dense crowds in confined spaces,a crowd evacuation guidance model based on intelligent signs is constructed in this paper.A balanced congestion strategy to optimize the signs layout and a social network search-based sign guidance weights optimization method are proposed to improve evacuation efficiency.Simulation experiments show that the optimized intelligent sign layout can effectively alleviate the local congestion during evacuation and reduce the time consumption of pedestrians caused by congestion.The optimized intelligent sign guidance weights can further balance the utilization rate of exits,which is conducive to making full use of the environmental resources to enhance the efficiency of crowd evacuation further.
