[0026] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0027] The road network can be abstracted into a weighted undirected graph model, which can be represented by a triplet G(V, E, W), where V represents the set of nodes in the undirected graph, and E represents the set of edges in the undirected graph , e ij ∈E represents the road node v in the road network i ∈V and road node v j The connection between ∈V can be directly reached; w ij ∈W represents edge e ij The number of mobile users that exist on .
[0028] A road segment refers to a sequence S=(v 0 v 1 ,v 1 v 2 ,...,v L-1 v L ), v i ∈V,i=0,1,...,L represents L+1 different points in the vertex set V, the starting point of the sequence v 0 and terminal v L degree is not 2. Obvious...
