Abstract
Movement guidance systems, devices, methods, and programs set a guidance branch point on a guidance route. The systems, devices, methods, and programs acquire a position and a shape of the guidance branch point and a prior branch point, and determine whether the prior branch point is adjacent based on the acquired information. The prior branch point is adjacent when the prior branch point exists within a first predetermined distance from the guidance branch point and is connected with a road in a same direction as the guidance branch point. When it is determined that the prior branch point is adjacent, the systems, devices, methods, and programs complete verbal guidance for the guidance branch point at a timing at which the movable body is located at a guidance end point that is located a second predetermined distance before the prior branch point.
