Modeling Road Network Vulnerability for Evacuees and First Responders in No-Notice Evacuation

Figure 1

The procedure of searching for the OEV of anchor node A: (a) the search region includes only node A; (b) the search region includes nodes A and B; (c) the search region includes four nodes, where the ratio reaches its maximum and node A’s OEV is derived; (d) the relationship between node A’s outbound vulnerability ratio and the number of nodes in the search region.
