PROBLEM TO BE SOLVED: To provide a technology for effectively retrieving an installation object of a notification object on the basis of information of the installation object independent from map data.SOLUTION: A route peripheral region including a guide route of a vehicle specified in map data is set (S104), and a speed camera installed in the route peripheral region is extracted as a candidate for a warning object (S105, S106). Then, on the basis of angle information indicating a direction in which the candidate for the warning object is installed, the speed camera not corresponding to a moving direction of the vehicle is excluded from the candidate for the warning object (S107-S109). Further, on the basis of position information indicating an installed position of the candidate for the warning object, the camera not placed on the guide route is excluded from the candidate for the warning object (S110-S112). |
