【摘要】：为改进传统Togawa行人疏散模型无法描述行人动态疏散特性的不足,在行人疏散动态交通特性分析的基础上,基于迭代思想和离散计算方法对传统Togawa模型进行改进,建立了改进的看台区行人疏散时间模型.以陕西省体育场大型活动为例,在行人交通特性分析的基础上,运用改进的疏散时间模型计算看台区行人疏散时间,并将改进的疏散时间模型、传统Togawa模型、Vissim行人疏散模型的仿真结果与实际计算结果进行对比分析.结果表明:改进的疏散时间模型的计算结果与实际调查结果的相对误差为4.4%,精确度最高;同时,改进的疏散时间模型充分考虑了行人疏散过程中的交通流特性,得到的疏散人数随疏散时间变化关系曲线更接近实际疏散过程.因此改进的行人疏散时间模型可以应用于大型体育场馆看台区行人疏散时间的计算.
[Abstract]:In order to improve the traditional Togawa pedestrian evacuation model which can not describe the pedestrian dynamic evacuation characteristics, based on the analysis of pedestrian evacuation dynamic traffic characteristics, the traditional Togawa model is improved based on iterative thought and discrete calculation method. Based on the analysis of pedestrian traffic characteristics, the improved pedestrian evacuation time model is used to calculate pedestrian evacuation time in stands area. And the improved evacuation time model, The simulation results of the traditional Togawa model are compared with the actual results. The results show that the relative error between the calculated results of the improved evacuation time model and the actual investigation results is 4.4, and the accuracy is the highest. The improved evacuation time model takes full account of the traffic flow characteristics during pedestrian evacuation. Therefore, the improved pedestrian evacuation time model can be used to calculate the pedestrian evacuation time in the grandstands of large stadiums.
