‘Rationality’ in Collective Escape Behaviour: Identifying Reference Points of Measurement at Micro and Macro Levels

Figure 7

Visual illustration of the spatial grid and penalty weights (image (a)), shortest weighted paths (image (b)) and actual mass trajectories of movements (image (c)). The presence of other pedestrians penalises the nodes and their adjacent links on the spatial mesh (grid) (image (a)). For every simulated pedestrian, once the choice of exit is simulated, the shortest weighted path on the grid is calculated between the location of the pedestrian and the mid-point coordinate of the chosen exit. That shortest path is subsequently truncated to generate a smooth path (image (b)).
