PURPOSE:To locate the position of an aimed vehicle on a map simply and in a short time. CONSTITUTION:When a dynamic state number (vehicle number) is inputted in an input element 4, the input element 4 notifies an information storage element 5 of the number and the information storage element 5 outputs an X-Y address of a vehicle of the notified dynamic state number, i.e., dynamic information, to a display area calculating element 2. The display area calculating element 2 calculates an area on a map which can be developed on a memory 6 when the address is disposed at the center of the memory 6, and outputs the result of calculation to information storage elements 3 and 5. The information storage element 3 outputs map information on the area to the memory 6 and the memory 6 receives and stores the information. Meanwhile, the information storage element 5 outputs to the memory 6 the dynamic information on all vehicles being present in the area, and the memory 6 stores it in corresponding addresses. The contents of the memory 6 are delivered to a display and the map and the dynamic information superposed thereon are displayed. |
