ABSTRACT:
A first recommended route is computed as having the minimum cost from a start point to an end point as a destination. The first recommended route is then divided by using each road name. Here, Tomei Expressway occupies 60% or more in the entire traveling length of the first recommended route while National Road No. 1 occupies 10% or more in the entire traveling length of the first recommended route. A link cost of Tomei Expressway is thereby multiplied by 1.5, while a link cost of National Road No. 1 is thereby multiplied by 1.2. Another route from the start point to the end point is re-computed by using the changed link costs. A detour avoiding Tomei Expressway and National Road No. 1 is thereby designated.
