Abstract
A satellite 10 in the sky has an imaging radar and a captured image data transmitting means, and captures an image of a predetermined subject area A including roads R. According to the captured image data concerning the subject area A, a traffic control section 21 grasps the state of traffic in the subject area A, and estimates a state of congestion according to thus grasped state of traffic. Also, according to thus estimated state of congestion, the traffic control section 21 sets parameters such as on/off times of signals. Thus set parameters are sent from the traffic control section 21 to their corresponding signals. The on/off of each signal is controlled according to the set parameters. Hence, the state of traffic in a wide area can be grasped quite accurately, and traffic can be controlled according to thus grasped state of traffic.
