摘要：

By analyzing the station environment impact on passenger evacuation behaviors, the calculation methods of attracting potential energy field for facilities and equipment as well as repulsive potential energy field for events and obstacles were proposed. Then an iterative generation algorithm of potential energy field based on the shortest distance was developed to describe the station environmental structure and the environmental impact mechanism on passenger behaviors. On this basis, a fusion method combining the potential energy field model and the improved social force model was put forward, and a dynamic simulation model for emergency evacuations in metro stations was established. Finally, Unity platform and C# programming technology were used to demonstrate and verify the proposed metood. © 2020, Editorial Department of Journal of Tongji University. All right reserved.
