      abstract     = {Although bidirectional motion on stairs can be commonly
                      observed for external stairs and in some transportation
                      facilities, a study that aims to investigate pedestrians'
                      walking characteristics under such conditions has never been
                      conducted. In this paper, we perform a controlled experiment
                      to study the bidirectional stair motion with varying flow
                      ratios. It is found that on average, ascending pedestrians
                      walk slower than those descending independent of the flow
                      ratio. At the same density, the average velocity is the
                      smallest for the full bidirectional flow when compared with
                      those in the descending and ascending ones, indicating that
                      the full bidirectional flow is not a simple combination of
                      unidirectional pedestrians. According to the individual time
                      to collision, congestion level and crowd danger, the run
                      when the flow ratio is 0.5 can be considered to be the most
                      critical with a large number of fierce conflicts. Thus, a
                      balanced ascending and descending flow situation should be
                      intentionally avoided for stairs where the bidirectional
                      motion may occur.},
