Embodiment Construction
[0036] The technical solutions of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. The following examples are implemented on the premise of the technical solutions of the present invention, and detailed implementation methods and processes are given, but the protection scope of the present invention is not limited to the following examples.
[0037] In order to better illustrate the present invention, choose as figure 2 small-scale road network, but the present invention is not limited by the scale and complexity of the road network in actual operation. from figure 2 We can see that the entire road network can be represented by a matrix A of order 5*5, including 8 source nodes, which can be divided into four types according to their directions about adjacent nodes. Specifically, A21 and A41 are WestS(Source, source node), A12 and A14 are NorthS, A25 and A35 are EestS, A53 and A54 are SouthS; ther...
