Research on Application of Intelligent Indication Signs in Improving Efficiency of Crowd Evacuation
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.
