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.
