Abstract

A CPU of a navigation device transmits probe information including link traveling information and average vehicle speed information at every predetermined time to an information distribution center. On the other hand, when receiving the probe information, a CPU of the information distribution center reads the road type corresponding to each link ID and user'"'"'s average vehicle speed during uncongested road traveling from the probe information, and determines the vehicle speed region corresponding to this link ID from a vehicle speed region determination table. Thereafter, the CPU of the information distribution center creates traffic information from this vehicle speed region and the probe information, stores it in a center side traffic information DB and statistically processes traffic information of a certain period to generate a link cost corresponding to a link ID and a time zone of a relevant vehicle speed region of statistical traffic information.

Claims

1. A traveling information creating device, comprising:

a collecting unit collecting traveling information of each link and an average vehicle speed for each road type as probe information from each of a plurality of vehicles; and

a traffic information creating unit classifying the probe information into predetermined vehicle speed regions based on the average vehicle speed for each road type and statistically processing the traveling information of each link included in the probe information for each of the classified probe information to thereby create traffic information of each link corresponding to the vehicle speed regions.

2. The traveling information creating device according to claim 1, wherein

the collecting unit collects as the probe information from each of the plurality of vehicles the traveling information of each link and the average vehicle speed while traveling a link of the same road type as the aforementioned link.

3. The traveling information creating device according to claim 1, wherein

the average vehicle speed is an average vehicle speed during uncongested road traveling.

6. The traveling information creating device according to claim 2, wherein

the average vehicle speed is an average vehicle speed during uncongested road traveling.

4. A traveling information creating method, comprising:

collecting traveling information of each link and an average vehicle speed for each road type as probe information from each of a plurality of vehicles; and

classifying the probe information into predetermined vehicle speed regions based on the average vehicle speed for each road type collected in the collecting step and statistically processing the traveling information of each link included in the probe information for each of the classified probe information to thereby create traffic information of each link corresponding to the vehicle speed regions.

5. A non-transitive computer-readable storage medium storing a computer executable program that causes a computer to perform the steps of:

collecting traveling information of each link and an average vehicle speed for each road type as probe information from each of a plurality of vehicles; and

classifying the probe information into predetermined vehicle speed regions based on the average vehicle speed for each road type collected in the collecting step and statistically processing the traveling information of each link included in the probe information for each of the classified probe information to thereby create traffic information of each link corresponding to the vehicle speed regions.
