Effect of partition line on jamming transition in pedestrian counter flow

Abstract

Abstract The effect of partition line on the pedestrian counter flow is investigated under the open boundaries by using the lattice-gas model of biased random walkers. There are two types of walkers without the back step: the one is the walker going to the right and the other is the walker going to the left. The right (left) walker prefers to move within (outside) the partition line. Right walkers interfere with left walkers near the partition line. When the density of right walkers increases under a constant value of left-walker density, the jamming transition between the freely moving phase and the stopped state occurs at a critical density depending on the left-walker density. The critical density is compared with that without the partition line. The partition line has an important effect on the jamming transition.
