Simulation results for spatial distances between the agents.

Shown are results for the clear widths w = 0.6 m (first row) and w = 1.0 m (second row), as well as for the escalator speeds vesc = 0.5 ms−1 (left) and vesc = 0.75 ms−1 (right), respectively. The average values of the distances are obtained from steady-state regions of 60s length (shaded areas) and are indicated by a bar. Since Δy almost vanishes in the upper two diagrams, the total distance s is approximately the same as Δx.
