In a subsequent phase focusing on both safety and traffic efficiency automatic driving would be employed relying on cooperative systems and eventually infrastructure control. A prototype IHS test system is being developed by ITS China in the Ministry s proving ground for highway and traffic. Current research focuses on automated lane-keeping based on magnetic markers in the road and in-vehicle devices working cooperatively. A sketch of the prototype system is shown in Figure . Japan 5-8 41 MLIT The Japanese ITS program is centered within MLIT. Major activities to advance IV R D and deployment are the AHSRA and the ASV program. AHSRA founded in 1996 focuses on test evaluation and implementation of cooperative vehicle-highway systems for the purpose of improving road safety. Membership consists of automotive and electronics companies within Japan. Cooperative vehicle-highway systems are a major focus based on the principle that onboard sensor systems are limited by the laws of physics and therefore cannot detect all hazardous situations. This is especially true for the winding curved highways that follow Japan s mountainous terrain. During AHSRA s first phase which concluded in 2003 three driver support levels were initially defined information control and full automation. Research then focused most strongly on the information and control levels with automation deferred for future phases. Concepts and requirements were defined for seven user services key to safety improvements which together comprise their Smart Cruise system Support for prevention of collisions with forward obstacles DGPS Cameras Cameras LCX Obstacles Information board Beacon Cameras Traffic accident Platoon Lane marker Frozen Roadside processing facility Infrared sensor Milliwave sensor - .
