- the information center 5000 accumulates the history information 330 received from the terminal device 5030 as the probe information 303.
- the accumulated probe information 303 is used for various purposes. In the present embodiment, as an example of the use, a case in which traffic statistical traffic information 504 is created and used will be described.
- FIG. 15 is a flowchart showing the flow of the statistical traffic information creation process. As illustrated, the process of creating the statistical traffic information 503 includes a process of classifying the probe information 503 (S310) and a process of processing the classified probe information (S320).
- FIG. 16 is a flowchart showing the flow of the classification process (S310) of the probe information 503.
- the arithmetic unit 901 of the information center 5000 reads the history information of each of the neutral users of the probe information 503 (S3102), and then deletes information that is not important in creating statistical traffic information. For example, since the information collected when the handbrake is ON can be determined to be information collected when the vehicle is parked, such information is deleted from the probe information 503. .
- the collection conditions (date and time, weather, link ID) of the history information are obtained (S3106), and classified for each collection condition (S3108).

- the link travel time is calculated for each. For example, in the travel history information 3310, since the travel history information 3312 recorded every time the link is crossed is recorded, the link travel time can be obtained from the date and time when the link is crossed. Then, the arithmetic unit 901 calculates the moving speed from the obtained link travel time and the length of the link (link length) (S3204). If the travel history information 3312 includes the link travel time, this processing can be omitted.
- arithmetic unit 901 determines whether the obtained moving speed does not exceed the speed limit, and if so, recalculates the link travel time using the speed limit as the moving speed of the link. Then, from the obtained link travel times, those that are out of the standard deviation are removed (S3208). Then, the average value of the remaining link travel times is obtained and used as the statistical value of the link travel times (S3210). Then, it is stored in the statistical traffic information 504 in association with the collection condition (date and time, weather, link ID) (S3212).

- the statistical traffic information recorded on the data recording medium 800 can be rewritten to the latest statistical traffic information, similarly to the rewriting of the map data. That is, in FIG. 13, the map data updating process has been described, but statistical traffic information may be updated instead of updating the map data. Also, the map data and the statistical traffic information may be updated at the same time. Even in such a case, the update fee can be changed according to the recording ratio of the history information.
- the statistical traffic information includes the link travel time for each collection condition. Therefore, the route search unit 42 of the in-vehicle navigation device 1000 receives the route search request. Then, using the link travel time as a cost, a route that minimizes the total cost from the departure point to the destination is searched by the Dijkstra method or the like. At this time, the route search unit 42 calculates the date and time to reach each link, and further obtains the weather forecast around the link at that date and time. Then, the link travel time of the collection condition that matches the date and time and the weather is extracted from the statistical traffic information, and is set as the cost of the link. By doing so, it is possible to search for a more appropriate and appropriate recommended route than when searching for a route using a link travel time in which the link length and road width are also fixed.
