Communication System Design of RACS (Road/Automobile Communication System) 912759
In Japan RACS standing for Road/Automobile Communication System has been studied for eight years. RACS is composed of three kinds of elements; on-board computer, beacon, center computer. RACS communication is a kind of radio communication link which connects the beacon and the on-board computer.
Research and development of RACS having been completed, the information service is selected among RACS services as the first step of practical use and realized as RACS information providing system.
The results of studying system design, making specifications, and executing experiments of RACS information providing system are described in this paper.
After analyzing system function, and the characteristics of RACS communication, the specification is made. In the result of the experiment, the specification is testified feasible and reasonable.
