• an unmanned transport vehicle configured to travel unmanned according to a control signal;
• one or more cameras configured to image a field on which the unmanned transport vehicle is to travel from above the field to generate a still image or video;
• and
• an operation control means configured to generate the control signal for controlling such that the unmanned transport vehicle travels on the virtual flow line based on the still image or video,
• wherein the operation control means comprises:
• a detecting portion configured to detect the unmanned transport vehicle from the still image or video;
• a position grasping portion configured to grasp a position of the unmanned transport vehicle in the field without being based on a sensor equipped with the unmanned transport vehicle using a result of a detection by the detecting portion;
• and
• a control portion configured to generate the control signal based on the position of the unmanned transport vehicle which the position grasping portion grasps.
