ドライブレコーダーによる交通事故詳細分析手法

抄録

Drive video recorders (DRs) have been installed on a plenty number of the taxicabs in large cities in Japan. This paper discusses how to carry out a detailed traffic accidents analysis using drive video recorder data obtained in Tokyo. The sequential motions of the cars concerned before and after the crash are illustrated throughout a process in the case studies of two traffic accidents. The causes of the accidents are discussed as well as measures to prevent the accidents and the DR data requirements for effective analysis based on the motion picture and the log data recorded by the commercial DRs. This newly-developed approach makes those possible to carry out the reproduction of the accident process, the estimation of the causes and the background factors, and the consideration of the preventive safety measures. It is more effective to make such analysis by using not only the DR data but also the Internet resources such as a map, an aerial photograph and other information. The requirements of DR hardware and DR data for the proper analysis of the accidents were also examined.
