多危險源場景下的人群疏散仿真方法研究
[Abstract]:With the rapid development of economy and society, the agglomeration of human beings increases gradually, and some unpredictable dangerous events often occur in the crowd movement. The emergence of these hazards to the safety of people's lives and property has caused a great threat, but also seriously affected the security and stability of society. It has become an important problem for the current social management to deeply analyze and study the movement state of the crowd after the occurrence of danger and realize the simulation of crowd evacuation in the complex scene. In order to solve the above problems, a method of crowd evacuation simulation is proposed, which is integrated into the mechanism of emotional infection under multiple risk sources. In this method, the psychological state and the exercise behavior of the crowd during the stress exercise were comprehensively considered, and the emotional infection mechanism under multiple risk sources was used to reflect the psychological state of the crowd to the exercise behavior in real time. Specifically, first of all, according to the inherent attributes of hazard sources, they are divided into different types, and the concept of hazard field is introduced to these different types of risk sources. And defined the transformation function between the danger intensity of different position and the value of individual panic emotion in the danger field. Then, a multi-risk individual emotional infection model is proposed to describe the spreading process of panic emotion in the population. Finally, by incorporating the mechanism of emotional infection into the traditional RVO model, a ERVO model is proposed to describe the behavior of crowd movement. The model combines emotional influence with obstacle avoidance in the process of crowd simulation for the first time. In addition to emotional factors, the change of individual physiological state will also affect the evacuation process of the crowd. Based on this, this paper proposes a crowd evacuation method combining physical exertion in multi-hazard scenarios. In the process of crowd evacuation, the correlation between individual physiological factors and emotional state is calculated in real time, and a method of crowd evacuation which is integrated with psychophysiological dual mechanism is obtained. Specifically, the physical performance of the individual is first modeled, and the real time physical exertion in the process of individual exercise is obtained, and then, by quantitative analysis of the relationship between the individual physical strength and the emotional state, the physical exertion is connected with the emotional infection. Finally, a ERVO model considering physical exertion was used to simulate the evacuation process. The experimental results show that the proposed evacuation method can generate more real group behavior in multi-hazard scenarios and can fully reflect the dynamic evolution of individual panic and physical conditions. The combination of psychological state and physical factors makes the proposed evacuation method more in line with the actual situation, and the simulation results are more authentic.
