Rear-end Incident Analysis Based on a Near-miss Incident Database

ヒヤリハットデータベースによる追突ヒヤリハットの分析

Image and vehicle data recorded by drive recorders are analyzed to clarify the difference of rear-end near-miss incidents between the low-speed (20 km/h or lower) and the high speed (40 km/h or higher) regions. The major understandings to be drawn from the analysis are as follows. There are significantly fewer relevant factors involved in the low-speed incidents than high-speed incidents. In the cases of low speed, small overlap cases account for a comparatively high percentage in the number of incidents whereas the actual accidents have different tendency. In the case of high speed, rear-end incidents after another car cuts in front of a subject car accounts for a considerably higher percentage compared with the low-speed cases.ドライブレコーダのデータを使用し,追突しそうな事象(追突ヒヤリハット)の発生状況を分析した.その結果,「低速ではオフセット状態で追突しそうになる状況が多いが,事故としてはフルラップが多い」,「高速では他車両が前方に割り込んだことになる追突ヒヤリハットが多い」等,速度域毎の特徴が明らかとなった.
