摘要：为探究大型公共场所内应急疏散调控策略的合理性、有效性和安全性,开展了2类场所的应急疏散调控策略的仿真研究,记录疏散时间、疏散拥堵时间和路径拥堵程度作为衡量应急疏散调控措施的指标,建立以多对多涟漪扩散算法为核心的线性元胞自动机模型。结果显示,与原有的疏散路线相比,使用算法规划的应急疏散路径可以缩短疏散时间;与仅仅使用算法规划应急疏散路径相比,考虑单一的路径拥堵情况或路网结构而增加的调控措施可能与疏散初衷相悖;但在使用算法规划路径的基础上,综合考虑路径拥堵情况和路网结构而增设的调控措施,其疏散效果是最好的。研究结果可为应急疏散管理者提供紧急情况下的调控策略,避免疏散过程中出现的拥挤、踩踏等二次事故的发生,进而保障人群的疏散安全。
To explore the rationality,effectiveness,and safety of emergency evacuation regulation strategies in large public places,we conduct simulation experiments for two types of places to verify the effect of regulation strategies.The evacuation time,evacuation congestion time,and path congestion degree are recorded as indicators to measure emergency evacuation regulation strategies.A linear cellular automaton model with ripple-spreading algorithm(RSA)to solve many-to-many POP as the core is established,i.e.,CRPS system.Firstly,as the input of CRPS,the system needs information about the road network information and personnel location distribution information of the evacuation site.The location of personnel is regarded as the origin node and the safe exit is considered the destination node.Secondly,according to the origin node and destination node information,many-to-many RSA calculates the evacuation path.Thirdly,CRPS starts working with the original and RSA evacuation path.And then,the evacuation time and node congestion can be obtained by evacuation simulation.According to the information,the evacuation effect of the original and RSA evacuation path is compared.Finally,the evacuation path is improved according to the evacuation effect.CRPS simulates again until an ideal evacuation result is obtained.The result shows that the RSA evacuation path can shorten the evacuation time compared to the original.Based on the RSA evacuation path,considering single path congestion or road network structure,the additional regulation strategies can be inconsistent with the original intention of evacuation.But the best effect is using RSA to plan the evacuation path with the path congestion and the road network structure.The research results can provide emergency evacuation managers with regulation strategies in emergencies.To avoid secondary accidents such as congestion and stampede in the evacuation process and thus ensure the evacuation safety of the population.
