A remote-operation apparatus wherein a communication unit receives detection data indicating the surrounding situation of an autonomous driving vehicle via a network from the autonomous driving vehicle. A display unit displays an image of the periphery of the autonomous driving vehicle generated on the basis of the received detection data. The communication unit transmits a control command including a second operation amount via the network to the autonomous driving vehicle that is being remotely operated, the second operation amount being obtained by correcting, on the basis of the characteristics of the autonomous driving vehicle, the first operation amount given to an operation unit by a remote-operator.
