Simulation of Single-File Pedestrian Flow under High-Density Condition by a Modified Social Force Model

In this paper, a new modified social force model is proposed to simulate the single-file pedestrian flow at high densities. Since pedestrians could only follow preceding person in flow, way which chooses their destination changed. It set as current position of pedestrian, rather than one fixed location. order possible movement densities, distance for calculating forces between was reset, and obstacles were divided into many particles. Next, values parameters ranges discussed. Furthermore, data from large-scale experiment used validations. The simulation results fundamental diagrams, spatiotemporal diagrams time–headway distributions show that can well. angular trajectories help understanding more about results. comparisons statistical local rates densities that, most cases, simulated experimental are quantitatively similar. This be good choice high-density simulations flow.
