Abstract
In this work the results of a pedestrian counterflow experiment in a corridor of width 2 m are presented. 67 participants were divided into two groups with varying relative and absolute size and walked in opposite directions through a corridor. The video footage taken from the experiment was evaluated for passing times, walking speeds, fluxes and lane formation, including symmetry breaking. The results include comparatively large fluxes and speeds as well as a maximal asymmetry between left- and right-hand traffic. The sum of flow and counterflow in any case turns out to be larger than the flow in all situations without counterflow.
