- AHS(Advanced Cruise-Assist Highway Systems)
- The Advanced Cruise Assist Highway System (AHS) is one of the most advanced systems in the ITS field. The goal of AHS is to reduce traffic accidents, enhance safety, improve transportation efficiency as well as reduce the operational work of drivers. A number of related effects are also expected. In Japan, AHS research is being carried out in the following fields:
AHS-“i” (information): focusing on providing information; AHS-“c” (control): vehicle control assistance; AHS-“a” (automated cruise): fully automated driving.
Many kinds of road-side infrastructures for monitoring highway conditions (such as other vehicles, obstacles, highway surface conditions and vehicle position), controlling the vehicle based on highway condition, and road-to-vehicle communications are necessary for the realization of AHS. Information such as traffic condition, weather and highway alignment is also required. As for vehicle functions, obstacle detection and avoidance, speed control, driving control and man-machine interface are required. The development of AHS-“i”, “c” and “a” should also consider compatibility with other ITS system components.

Research and development are promoted through the joint efforts of the Ministry of Construction and the AHS Research Association.
The Ministry of Construction is promoting research and development of AHS in cooperation with the Advanced Cruise-Assist Highway System Research Association. In September 1996, a test run took place on the part of the Joshinetsu Expressway, between Komoro IC and Tobu-Yunomaru IC which was not yet open. The test run consisted of continuous automatic driving on an 11-km-round-trip, and a safe driving system of collision prevention and lane deviation prevention.
