A configuration for controlling safe switching of automatic driving and manual driving includes a driver information acquisition unit that acquires driver information of a movement device such as an automobile, an environmental information acquisition unit that acquires environmental information of the movement device, and a safety determination unit that receives, as an input, the driver information and the environmental information, and learns and calculates a safety index value indicating whether or not a driver in the movement device during automatic driving is in a state of being able to perform safe manual driving. The safety determination unit further estimates a manual driving recovery available time including a time required until the driver in the movement device during the automatic driving becomes able to start the safe manual driving.
