Embodiment Construction
[0074] In this embodiment, a road network evacuation planning method based on the maximum flow rate path priority is applied to the simulated directed road network structure G(V, E), and in the simulated directed road network structure G(V, E) , V represents the node set, and V={V s ,V z ,V d}, the construction result is as follows figure 1 shown; V s represents the source node set, V z Represents the intermediate node set; V d Indicates the destination node set; and has: V s ={V 1 ,V 2 ,...,V i ,...,V a}; V i Denotes source node set V s In the i-th source node, and V i ={V i,cap ,V i,occ}, V i,cap Denotes source node set V s The i-th source node V in i The node traffic capacity of V i,occ Denotes source node set V s The i-th source node V ini The initial capacity to be evacuated, 1≤i≤a, in road network evacuation, the source node set represents the place where the accident occurred and the population is relatively dense, such as office buildings, supermarke...
