摘要： A travel time data processor extracts a link that is present in the neighborhood of a target link, as a reference link. The travel time data processor selects an identical time zone of the reference link that is identical with the time zone of the target link in which the number of sample data is less than a reference number, and searches for another time zone having similar statistical data to that of the selected time zone. The travel time data processor adds the number of sample data in a time zone of the target link corresponding to the searched another time zone of the reference link to the number of sample data in the time zone of the target link that is equal to or less than the reference number, and generates statistical data from the summed-up sample data.

摘要： There is provided a method of collecting probe information generated during travel of a vehicle, comprising: (a) receiving probe information including travel time information of a reference area, from a vehicle traveling a reference area that includes at least one of an intersection area that is an area from an approach to an intersection to an exit from the intersection and a road area that connects with the intersection area and is an area from the exit of the intersection to an approach of another intersection adjacent to the intersection in an exit direction; and (b) storing the received probe information.

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 include 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： An analyzer of the invention adequately analyzes a change in road network by using probe information generated with driving of a vehicle. This analyzer determines a traffic amount of vehicles passing through a specified section included in the road network from a plurality of the probe information accumulated over a predetermined period. The analyzer also determines a discontinuity rate, which is a rate of incidents that vehicle locations are discontinuous in the specified section, from the plurality of probe information accumulated over the predetermined period. The analyzer detects a change in the road network, based on a degree of change between traffic amounts in two different periods with respect to the specified section included in the road network and a degree of change between discontinuity rates in the two different periods. The detected change in the road network can be used for survey of the road network. [Drawing selected] Fig. 1

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).
