Modeling and Simulation of Rail Transit Pedestrian Flow

The law and basic characteristics of rail transit pedestrian flow movement are closely related to rail transit construction and operation. Under the background of China's large-scale rail transit construction and the expansion of operation ground, as a key factor, the safety and organization of mass and high-density pedestrian flow in rail transit has received wide attention. This paper reports an excessive overlap avoided behavior rule model based on the existing social force model, through improving the driving force, attractiveness and direction influence in the model parameters, and rectangular scope was also introduced in model calculation to reduce the computing time. This paper examines the conditions for which the model can be beneficial to the human behavior reflection in terms of automatic drainage phenomenon appearance and the arch formed in the station of exit in rail transit pedestrian flow motion. Finally, this paper uses Visual C++ 6.0 to create the SubPeds pedestrian flow simulation experiment platform, by setting the one-way virtual pedestrian flow scenarios, the model is simulated and the simulation data is analyzed. The results show that the proposed model accurately simulates pedestrian movement.
