Background of the development of AHS (Advanced Cruise-Assist Highway Systems)
Background of the development of AHS (Advanced Cruise-Assist Highway Systems)
| 1989: The Ministry of Construction (MOC) (now Ministry of Land, Infrastructure and Transport) begins AHS research and development. - Research into traffic accidents |
| 1991: Public-private research by the national government,including MOC and 24 private companies, in the field of the automated cruise. |
| 1993: The concept of phased development of AHS was published in "MICHI", a publication specifying the MOC five year program on roads. |
| 1995: In November, the world's first AHS demonstration at the Public Work Research Institute (PWRI) of MOC in Tsukuba Research Center, Ibaraki Prefecture. |
| 1996: In September, AHS demonstration at a new segment of highway before it was open to the public. - The demonstration aimed to evaluate and identify problems regarding application of AHS for use on actual highways. - The demonstration included warning against road danger ahead, prevention of collision, prevention of lane departure and automated cruise. |
| 1996: Establishment of the Advanced Cruise-Assist Highway System Research Association(AHS Research Association). |
| 1997: The Concept of AHS-i (information), -c (control), and -a(automated cruise), which is the developed version of the concept of phased development of AHS, and "User Services" were published. |
| 1999: "AHS requirements" for safety were released, and development of key technologies for AHS started. |
| 2000: A Joint tests on Advanced Safety Vehicle (ASV) and Demo2000 were conducted at the Public Works Research Institute (Ministry of Construction*) in Tsukuba City. *The Ministry of Construction was merged into the Ministry of Land, Infrastructure and Transport in January 2001. |
| 2001: A verification test system was constructed in conjunction with ASV. |
| 2002: "Proving Tests 2002" including tests on actual road (at seven sites nationwide) was conducted. - Tests were conducted, focused on Cooperative Vehicle-Highway Services, Infrastructure-based services, and utilization for road management. - Three fields were used; test courses, driving simulators and actual roads. |
