Abstract

To explore the variation of pedestrian density in merging channel of the subway station, a modified lattice gas model with biased random walkers is proposed to simulate the merging process of pedestrian flows in the Y-shaped channel in peak hour under open boundary conditions. The model consists of both square and triangular lattices and uses C ++ and QT creator to mimic the merging process of two inlet flows intersected at any angle. After simulation, we propose a three-dimensional phase diagram and analyze the relationship between the merging flow density and the inlet channel width, as well as the offset angle. The simulation results also show that the jamming transition of the Y-shaped channel occurs when the inlet flow densities are 0.4 and 0.3 respectively, and the maximum merging flow density is at around 0.58. In addition, the merging flow density has a correlation with the inlet channel width and the strength coefficient of pedestrian movement, but is not affected by the channel’s offset angle.
