  We conducted numerical simulation for a crowd of pedestrians. Each
pedestrian, modeled with three circles, has a shape whose long axis is
perpendicular to the anteroposterior axis, and is designed to move fixed
destination. The pedestrians have friction at the surface and soft repulsion.
In this study, we newly introduced an active rotation which captures
psychological effect to evade face-to-face situation. The numerical simulation
revealed that active rotation induces fluidization of system leading to higher
flux of pedestrian. We further confirmed that this fluidization is due to
fragmentation of force chain induced by the active rotation.
