报告简介：
The pedestrian flow is one of the most complex systems with large populations of interacting agents. The models in the microscopic and macroscopic scales have different advantages when studying the related problems. In general, the microscopic models can describe the interaction force at the individual level. But the macroscopic models can provide more analytical results on the global interaction and the overall dynamics in a long time, along with efficient numerical simulations and predictions. In this study, based on the original social force model with an optimal route choice, we derive the kinetic equations at the mesoscopic level. Varying the interaction force in different scenarios, we derive several continuum models at the macroscopic level. Finally, numerical examples are given to evaluate the behaviors of the social force model and our continuum models
