交通安全に関する個人の基準はそれぞれであり，従来は特に基準はなく個人の感性や一般論で評価されることが多かった。この問題を解決するために運転を定量的に記録する装置としてドライブレコーダーが開発され，記録されたデータを評価するシステムが開発されてきた。本稿では，これらの最新の運行管理装置とシステムを紹介する。
Personal standards on road safety vary among individuals. Previously there were no definite road safety standards; as a result, many evaluations have been done on the basis of personal senses or common belief. As a solution to these problems, Drive Recorder＊1 have been developed to obtain quantitative records of driving, and systems for data evaluation have accordingly been pursued. In this report we introduce the most recent models of these devices and systems.
*1: Drive Recorder: An Drive Recorder is a device to record driving data and picture images on a memory card or other storage media when triggered by an impact shock or sudden braking caused by an accident or a near-miss incident. The driving data contains records on acceleration, braking ,speed, turn signals and GPS while the picture images shows the moments before, during and after the shock.
