Abstract
A route guidance system includes a current position detection section, a route search section, and a guidance section. The guidance section includes a branch computation section computes the number of branches between a host vehicle location and a guidance location along a specified route. A point guidance section executes route guidance based on the computed number of the branches. The number of branches between the host vehicle location and the guidance location is computed, and the route guidance is executed based on the computed number of the branches, so it is possible to recognize the guidance location simply by counting the number of the branches, regardless of the number of traffic signals that exist between the host vehicle location and the guidance location.
