Abstract

A traffic-controlled route where a mobile body is prohibited from proceeding to a control end point via a control start point and an intersecting passing point is shown by a traffic control information (510) that has a single data structure in which, for instance, a first node information (512A) defining the control start point, a second node information (512B) defining the intersecting passing point and a third node information (512C) defining the control end point are associated in an order of existence on the traffic-controlled route. Accordingly, a traffic-controlled route in which, for instance, a left turn is prohibited can be shown by the traffic control information (510) including information of points located on this traffic-controlled route, so that a virtual point or route does not have to be newly set. Therefore, the traffic control information (510) capable of showing the traffic control with a simple structure can be provided.
