PROBLEM TO BE SOLVED: To provide a navigation device that can suppress an unnecessary guidance for a user.SOLUTION: When a HOV lane and a normal lane are defined by a single link and it is determined that a road branching only from the HOV lane in a route section in which the normal lane in the route is travelled exists on the basis of map information having information showing whether or not the HOV lane is provided side by side included in link data, even if a Bifurcation flag is set at a branch point where the road branches only from the HOV lane, a control section 30 suppresses a guidance relating to a branch road. |
