Abstract: Navigation apparatus, methods, and programs merge and correct a plurality of types of past traffic information. The apparatus, methods, and programs may store a plurality of types of past traffic information, each type of past traffic information having a priority and may merge the stored past traffic information in accordance the priorities. The apparatus, methods, and programs may detect adjacency relationships among the plurality of links; and, if a detected link number indicates that the corresponding link is not adjacent to adjacent links, replaces the detected link number for the link, the replaced link number indicating that the link is adjacent to the adjacent links.

Abstract: Systems, methods, and programs determine whether it is possible to generate statistical values based on a number of pieces of travel history information and a degree of contingency of traffic information in the travel history information. Systems, methods, and programs display, if a predicted travel time is greater than a typical travel time, at least one of a predicted travel time, a predicted arrival time, or a route in a manner that indicates that the predicted travel time is greater than the typical travel time; or display, if the predicted travel time is less than the typical travel time, at least one of the predicted travel time, a predicted arrival time, or the route in a manner that indicates that the predicted travel time is less than the typical travel time.
