NAVI-SERVER, NAVI-CLIENT, AND NAVI-SYSTEM

摘要

Provided is a navi-system or the like capable of improving accuracy of road traffic information that is created based on probe information. A navi-client 2 creates probe information including an identifier that represents a detection result as to whether a communication with a vehicle-mounted device 3 has been established or not. A server communication device 1 discriminates or selects probe information in accordance with a difference of the identifier, and creates road traffic information based on the thus discriminated or selected probe information.

主权项

1. A navi-server, comprising:
a first server arithmetic processing element that is configured to receive, from a navi-client, probe information representing a time-series change manner of a position of the navi-client; a second server arithmetic processing element that is configured to create road traffic information based on the probe information; and a server storage device that stores the road traffic information, wherein the first server arithmetic processing element is configured to receive the probe information including an identifier representing a communication state between the navi-client and a device mounted on designated travelling means or attachment/detachment of the navi-client with respect to an instrument attached to the designated travelling means, and the second server arithmetic processing element is configured to discriminate or select the probe information in accordance with a difference of the identifier, and generate the road traffic information based on the discriminated or selected probe information.
