Abstract
Pedestrian counter flow is investigated by experiment and simulation. The experiment is performed for the channel with open boundaries. Two types of walkers, going to the right and to the left, are taken into account. The video recordings and measurements of individual arrival times are evaluated. The pattern formation and jamming transition are discussed. The experiment is mimicked by the lattice gas simulation where each person is simulated by a biased random walker taking into account following the front persons with the same direction. The experimental result is compared with the simulation result. It is shown that the arrival time obtained from experiment is consistent with that of the simulation. Also, the jamming transition does not occur in the experiment because of the finite size effect.
