ヒヤリハットデータによる歩行者の飛び出し行動の分析とモデル化

This study focuses on dash out behaviors of pedestrians, which is one of the most unsafe behaviors with the object of traffic safety. Since passengers’ fatalities of automobiles have been decreased remarkably thanks to passive safety technology and preventive safety technology, it is desired to reduce the pedestrian fatalities for the future. For this reason, this study sets its final goal to develop an active safety technology to prevent pedestrian accidents. In this study, we focused on the near-crash incident scene with a car by dash out behaviors of pedestrians. Therefore, the dash out behaviors of pedestrians are first extracted from near-crash incident database and then analyzed the feature of dash out behaviors of pedestrians quantitatively. Next, a mathematical model expressing dash out behaviors is proposed based on the analysis results. As a result, it is confirmed that the pedestrian model reproduces the behavior of the pedestrian, capturing the feature of the behavior of the real pedestrian.
