Fuzzy Roadway selection Decision support System Concerning Roadway Repair Works and Traffic Accidents

近年，わが国の自動車の普及台数は増加する一方で，特に都心部において交通渋滞には著しいものがある。また．都内中心部の道路網は複雑化し．慣れないドライバーにとってその行程選択は難しくなっている。そこで．最短距離．最短時間．最も走り易い行程．最も分かり易い行程の4つについてドライバーに適切な行程を示すシステムを開発した。さらに．本論文では道路上で事故が起きたときや．工事があったときの迂回方法も示す。A fuzzy based decision support system on roadway selection in Tokyo metropolitan district has been reported. The optimality was discussed from three viewpoints i.e. minimum distance, minimum time required, understandability. In this report the system has been improved drastically from the following 3 view points. 1. Covered area becomes about 4 times larger than that of the previous system. 2. A new optimal measure called driving easiness is introduced. 3. An optimal roadabout way is suggested in the case of roadway repair works of traffic accidents.Several typical experimental reaults are demonstrated to confirm its performance for practical use
