無信号交差点右折時における交差車両衝突回避支援システムの開発

抄録

Recently, the percentage of traffic accident by elderly driver is increasing. According to researches of all accident types, the accident rate by the elderly drivers at right-turn in unsignalized intersection is higher compared to young drivers. This study develops the collision avoidance assistance system with crossing vehicle in unsignalized intersection rightturn. First, this paper describes the system to search the command value of waiting time and acceleration by using the cost function on the right-turn model and risk assessment index. Next, to evaluate the five types of cost function, the subjects evaluated each assistance system using driving simulator. In the experiment, the subjects evaluated the systems in three scenario; 1) system-equipped vehicle merge the front of the ego vehicle 2) system-equipped vehicle merge the rear of the ego vehicle 3) ego vehicle is controlled by the assistance system automatically. Finally, the experimental results show that the right-turning assistance systems are acceptable for drivers.
