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.
