摘要： A route search apparatus configured to search a route from a set place of departure to a set destination comprises network data that includes nodes and links representing a road network, an average cost value indicating an average of travel time of each of the links, and a variance value indicating a degree of variance of the travel time, and a route searcher configured to determine the route from the place of departure to the destination as a recommended route, based on the average cost value, the variance value and a weight coefficient of the variance value.

摘要： 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.
