Dynamic Sign Guidance Optimization for Crowd Evacuation considering Flow Equilibrium

Figure 2

The discretization of space with sign direction and its corresponding directed network. Figure (a) and (c) are the same discrete space with different sign directions, and Figure (b) and (d) are directed networks corresponding to Figure (a) and (c), respectively. In Figure (c), the sign direction in grid B and grid C points in the opposite direction compared with Figure (a). Accordingly, the corresponding directed network is reformed from Figure (b) to Figure (d) by changing the arc direction between node 13, node 14, and node 10.
