摘　　要：为分析不耐烦心理和建模策略对多速度等级行人疏散仿真结果的影响,以场域元胞自动机模型为基础,采用间接算法思路实现多速度等级的表达,引入个体级实时的不耐烦水平处理同步更新模式下的冲突解决问题以及顺序更新模式下的更新顺序问题,构建基于NetLogo的仿真环境,通过仿真实验对比分析在不同的更新策略与冲突解决策略下疏散效率的差异。研究结果表明:多速度等级方案与单速度等级方案相比,行人疏散时间延长;考虑不耐烦水平的方案和对照方案相比,高期望速度人群的疏散效率增加,因为其竞争力更强,但低期望速度人群的疏散效率显著降低,从而导致总体疏散时间的延长;顺序更新模式下多速度等级行人的平均即时速度普遍高于同步更新。研究结果可为公共场所应急疏散管理中的人群行为建模与多速度场景仿真策略优化提供理论参考。In order to analyze the influence of impatience psychology and modeling strategy on the simulation results of pedestrian evacuation with multi-speed grades,based on the field cellular automata model,the idea of indirect algorithm was adopted to achieve the expression of multi-speed grades,and the real-time impatience level at individual level was introduced to deal with the conflict resolution problem in synchronous update mode and the update order problem in sequential update mode.A simulation environment based on NetLogo was constructed,and the difference of evacuation efficiency under different update strategies and conflict resolution strategies was compared and analyzed through simulation experiments.The results show that the evacuation time of pedestrian in multi-speed grades scheme is longer than that in single-speed grade scheme.Compared with the control scheme,the scheme considering the impatience level presents an increase in evacuation efficiency for high expected speed groups due to their stronger competitiveness,but a significant decrease in evacuation efficiency for low expected speed groups,resulting in an extension of overall evacuation time.The average instant speed of pedestrian with multi-speed grades in sequential update mode is generally higher than that in synchronous update mode.The research results can provide a theoretical reference for crowd behavior modeling and multi-speed scene simulation strategy optimization in emergency evacuation management of public places.
