常時記録型ドライブレコーダを用いた交差点右折行動の環境危険度の分析
Analysis on Environmental Hazard in Right Turn Behavior Using Continuous Sensing Drive Recorder
交差点右折時に横断歩行者や自転車に接触する事故の頻度が依然高いことから，横断歩行者および自転車衝突事故を防ぐ安全運転評価手法の構築が求められています．
本研究室では，常時記録型ドライブレコーダで収集した市街地走行データに基づき，通常時の運転状況および対歩行者衝突事故のニアミスの解析と危険場面の抽出を行い，
危険要素の解明をすることにより，自動車の各種予防安全技術の効果把握，安全技術の開発を行っています．
RESEARCH ABSTRACT
This research addresses an analysis of driving behavior in right turn behavior from the collected driving database in urban area by using continuous-sensing drive recorder.
First, driving data is acquired by using experimental vehicle equipped with the continuous sensing driving recorder.
The right turn behavior database is constructed to evaluate normal driving behavior and clarify relevant factors of human error at intersection.
The pedestrian and bicycle cognitive behaviour of individual driver during right turn at a fixed intersection is focused.
To pick out the unsafe driving behaviour from the database, the pedestrian/bicycle collision threat assessment in right turn behaviour is conducted based on the predictive value of
relative distance between the host vehicle and other moving objects at the intersection.
The situation of the unsafe driving behaviour is inspected to check.
