项目摘要

The purpose of this research was to make the microscopic model and develop the simulation program in order to estimate the macroscopic behavior of crowed people. We carried out the experimental study to make the simulation model. Based on the experiment, we perform modeling the behavior of pedestrians and crowed by means of the lattice gas model. We forecasted the dynamic behavior of crowed people by performing the computer simulation. We clarified the behavior of crowed people in the four cases.(1)The evacuation from a classroomBy carrying out the evacuation experiment of students from a classroom, we made the simulation model for the dynamical behavior of the evacuation. We calculated the escape times, escaped trajectories, and the dependence of the escape time on the initial position. We reproduced the evacuation experiment by the simulation.(2)Jamming transition in the counter flow of pedestrianWe carried out the experimental study for the counter flow of pedestrians to avoid the jam in the rush hour or in the event. Based on the experimental result, we made the dynamical model. We estimated the emergency of the jamming by simulating the model numerically.(3)Evacuation without visibility in the fire accident or the electric breakdownIn order to mimic the evacuation without visibility, we carried out the evacuation experiment of students by wearing the eye mask. We found the characteristic properties of the evacuation. Based on the characteristics, we made the dynamic model and performed the computer simulation. We estimated the dynamical behavior of people without visibility.(4)Evacuation process of people going on all foursWe carried out the experimental study for students which did not walk on standing. We simulated the evacuation process of crawlers. We developed the simulation program for the evacuation of crawlers. We compared the crawler evacuation with the walker evacuation.

本研究的目的在于建立微观模型并开发仿真程序，以评估拥挤人群的宏观行为。我们进行了实验研究，制作了仿真模型。在实验的基础上，利用格子气模型对行人和人群的行为进行了模拟。通过计算机仿真，预测了拥挤人群的动态行为。我们在这四个案例中阐明了拥挤人群的行为。（1）教室内人员疏散通过对教室内学生疏散的实验，建立了教室内人员疏散的动态仿真模型。我们计算了逃逸时间，逃逸轨迹，以及逃逸时间对初始位置的依赖关系。通过模拟再现了疏散实验。（2）行人逆向流动中的拥堵过渡我们对行人逆向流动在高峰时段或活动中避免拥堵进行了实验研究。根据实验结果，建立了动力学模型。通过对模型的数值仿真，对干扰的紧急程度进行了估计。（3）火灾事故或电气故障时的无能见度疏散为了模拟无能见度疏散，我们进行了学生戴眼罩的疏散实验。我们发现了疏散的特征。根据这一特点，建立了动力学模型，并进行了计算机仿真。我们估计了人们在没有可见性的情况下的动力学行为。（4）四人步行的疏散过程我们对没有站立行走的学生进行了实验研究。模拟了爬行动物的疏散过程。我们开发了爬行动物疏散的模拟程序。我们比较了履带式疏散和步行者疏散。
