Abstract: 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.

Abstract: Route search systems, methods, and programs search for a recommended route for transfer with switching between a plurality of transportation modes. The systems, methods, and programs acquire link information for specifying a link for transfer by each of the plurality of transportation modes and connection information related to connection between links for transfer by different transportation modes, and set a condition for switching from a first transportation mode to a second transportation mode, which is different from the first transportation mode, on the basis of a combination of the first transportation mode and the second transportation mode. The systems, methods, and programs search for the recommended route for transfer with switching between the plurality of transportation modes on the basis of the link information, the connection information, and the set condition, the recommended route connecting links for transfer by different transportation modes.

Abstract: Route search systems, methods, and programs search for a recommended route using a cost value of a link or a node that constitutes a route. The systems, methods, and programs calculate the cost value of the link or the node on the basis of calculation material information that serves as a material for calculating the cost value, and specify a reliability degree of the calculated cost value of the link or the node on the basis of a number of pieces of the calculation material information used to calculate the cost value of the link or the node. The systems, methods, and programs correct the cost value of the link or the node, the reliability degree of which has been specified, on the basis of the specified reliability degree, and search for the recommended route using the corrected cost value.
