Abstract
In a vehicular navigation system which provides a recommended travel route, a control unit checks for the number of each road branching from an entering road of the travel route at an intersection when the entering road has a plurality of traffic lanes. If an exiting road of the travel route from the intersection has a largest number of traffic lanes among the branching roads, no intersection guidance is provided. If the exiting road has a smaller number of traffic lanes, an intersection guidance is provided. This intersection guidance may include guidance of turn direction and guidance of traffic lane to be taken.
