ドライブレコーダを用いたヒヤリハット分析に関する研究(第2報): 収集データによる分析手法とデータベースの構築

摘要

平成17年の交通事故死者数は6871人にまで減少したが， 事故件数は約93万件，負傷者数は約116万人と高いレベル にあり，死者数減だけでなく，事故そのものを防止する対策 が必要である．交通事故防止のためには，「ひと，みち，く るま」のそれぞれの観点からの取組みが必要であり，特に車 両技術としては，予防安全技術の開発と普及が望まれる．%Recently, the number of fatalities in Japan has decreased gradually by development of safety technologies, whereas the total number of accidents and injuries has been increasing. One effective way to decrease the number of accidents is considered to investigate the near-miss incident. Our research project aims to construct large-scale database of incident which is useful to analysis traffic accident. In order to do this, two types of drive recorder, widespread type and high-performance type have been developed, and large scale field tests have been conducted. This paper shows examples of the captured data and discussions for our approach using drive recorders, and also the framework of the newly constructed large scale database of the near-miss incidents. Some macro analysis indicates characteristics of the near-miss incidents as compared with that of accidents, and they show effectiveness of our approach.
