An analyzing apparatus includes a result-data storing unit that determines whether result data that is calculated as a result of analysis is restorable by linear interpolation. If the result data is determined to be unrestorable by the linear interpolation, the result-data storing unit stores the result data in a predetermined storage unit. Moreover, the analyzing apparatus includes a data restoring unit that reads the result data from the storage unit. The data restoring unit performs the linear interpolation using the result data acquired, thereby restoring the result data.

Conventionally, different traffic information cannot be sent in accordance with an output reason of a request to send. According to the present invention, a request to send traffic information, which is output in response to an instruction given by a user operation or an automatically given instruction, is acquired, an output reason of the request to send is determined, and a communication unit is controlled so that the traffic information on different areas is sent depending on the cases where the output reason is the instruction given by the user operation or the automatically given instruction.

Search criterion information, which indicates a search criterion is transmitted to a search server, destination point information on a destination point, which is a point found by the search server based on the search criterion, is obtained, a candidate point database that stores candidate point information on a candidate point connected to a road in association with the candidate point is searched, the candidate point associated with the candidate point information having a similarity to the destination point information, higher than or equal to a predetermined reference similarity, is identified as an arrival point, and first guidance information that indicates a first route to the arrival point is generated when the arrival point has been identified and second guidance information that indicates a second route to a point closest to the destination point among points on roads is generated when the arrival point has not been identified.

When a destination is set, a CPU transmits to an information distribution center average vehicle speed information and so on together with a request command requesting for statistical traffic information. On the other hand, a CPU selects statistical traffic information per vehicle speed region of a predetermined vehicle speed region for each secondary mesh to thereby search for a basic route to the destination. Subsequently, the CPU identifies a vehicle speed region for each road type from the average vehicle speed information and a vehicle speed region determination table, selects for each mesh ID of all the secondary meshes through which the basic route passes the statistical traffic information per vehicle speed region corresponding to the vehicle speed region identified for each road type from the statistical traffic information per vehicle speed region classified by road types, and distributes it to a navigation device.

A traffic information generation method for generating traffic information for each link includes a vehicle speed detection step of detecting a vehicle speed at predetermined distance intervals or at predetermined time intervals using a vehicle speed sensor; and a traffic jam degree detection step of referring to a specified speed and a specified distance prescribed in association with a traffic jam degree representing a level of a traffic jam and a connection determination distance prescribed in accordance with a road type to detect the traffic jam degree corresponding to the vehicle speed. When a link length falls within a predetermined range, information on the traffic jam degree corresponding to a fastest vehicle speed within a prescribed starting point distance from a beginning of the link is allocated to the link.

Navigation information distribution systems, methods, and programs transfer a piece of vehicle position information to an information distribution center every predetermined time period, the piece of vehicle information including a vehicle position and a time when the vehicle passes through the vehicle position. The systems, methods, and programs receive pieces of vehicle position information and traffic information including congestion information, store the received pieces of vehicle position information in order of arrival, and specify a congested road section on the basis of congestion information. The systems, methods, and programs assign a weight of a first travel distance within the congested road section, the weight of the first travel distance calculated on the basis of two of the received pieces of vehicle position information received from the navigation apparatus and congestion information about the congested section. The systems, methods, and programs calculate a first travel time corresponding to the first travel distance, calculate the congested section travel time necessary for passing through the congested section based on the calculated first travel time, and distribute the calculated congested section travel time to a navigation apparatus.
