Dynamic guidance strategy and path optimization method for crowd evacuation in large space public buildings based Multi-agent modeling and simulation

At present, the proportion of stampede accidents in large space public buildings is relatively high, and it is easy to cause secondary casualties in emergencies. Guidance evacuation based on guiders can effectively avoid trampling and improve crowd evacuation efficiency. It has been a vital evacuation strategy in recent years. To improve personnel safety and efficiency in evacuation processes, a real-time dynamic guidance strategy is proposed, and a path optimization method cooperated with a dynamic guidance strategy is also put forward for obstacle avoidance. A real stadium is taken as a case to study and verify the validity of the method based on Multi-agent modeling and simulation technology. In the future, it should be considered to apply in emergency management and control in reality.
