The flow of the V-W algorithm. The V-M algorithm is made up of three stages. The first stage, pre-processing stage, adopts the voronoi map to divide the road network. The second stage, road search stage, mainly implements the search in the output road set of the pre-processing stage. The third stage, extended search stage, is if the second stage cannot find the targeted road, the extended search must be implemented in the neighboring area.
