  In this work the results of a pedestrian counterflow experiment in a corridor
of a width of 2 meter are presented. 67 participants were divided into two
groups with varying relative and absolute size and walked in opposite direction
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.
