Figure 4.

Numerical simulations as compared to experimental observations during conditions 2 and 3. In (a,b), the blue lines correspond to the average observed trajectories, with pedestrians moving from left to right. The blue dashed lines indicate the standard deviation. Red lines correspond to the average trajectories obtained after 1000 simulations (with parameter values A=4.5, n=2, n′=3 and 0.005). Bars in (c,d) indicate the proportions of choosing the left- or right-hand side in an avoidance manoeuvre during the experiment (blue bars) or in simulations (red bars).
