Route search devices, systems, and programs obtain current traffic information indicating traffic conditions at a present time and obtain statistical traffic information, the statistical traffic information being statistical information obtained by collecting statistics of histories of traffic information. The devices, systems, and programs determine a degree of traffic congestion of a road at the present time, identify travel time for a road whose degree of traffic congestion is greater than or equal to a threshold, based on the current traffic information, and identify travel time for a road whose degree of traffic congestion is less than the threshold, based on the statistical traffic information. The devices, systems, and programs then search for a route to a destination, using the identified travel time.
