An information management center 20 transmits second probe information managed by the information management center 20 to an on-vehicle system 10 on the condition that the information management center 20 is provided with first probe information collected by the on-vehicle system 10. The on-vehicle system 10 transmits user ID information to the information management center 20 together with the first probe information only when it is judged that a user has an intention of transmitting the user ID information. The information management center 10 gives a discount point for a use fee of the second probe information only when the information management center 10 receives the user ID information together with the first probe information. Thus, information can be collected from a greater number of mobile terminals.
