    摘要： A route search system, a route search method, and a computer program capable of finding a more appropriate route for a user are provided. A probe center 4 collects probe information from vehicles 3 that travel across the country, and a navigation apparatus 2 calculates the link cost of a link on the basis of the probe information in the case where a search for a recommended route is performed (S2). The reliability degree of the calculated link cost is specified on the basis of the number of pieces of the probe information used to calculate the link cost of the link (S3). The value of the link cost, the reliability degree of which has been specified, is corrected on the basis of the specified reliability degree (S6). A search for a recommended route is performed using the corrected value of the link cost (S7).

    摘要： There are provided a route searching device, a route searching system, and a computer program that allow to search for a more appropriate route by identifying accurate travel time for a road based on traffic information, without increasing processing load. Specifically, each of current traffic information indicating traffic conditions at the present time and statistical traffic information which is statistical information obtained by collecting statistics of histories of traffic information is obtained, a degree of traffic congestion of a road at the present time is determined, and travel time for a road whose degree of traffic congestion is greater than or equal to a threshold is identified based on the current traffic information, and travel time for a road whose degree of traffic congestion is less than the threshold is identified based on the statistical traffic information. Then, a route search is performed using the identified travel time.
