| 抄録（英） | Automated/autonomous vehicles are expected to be as safe as or safer than human drivers, as they are expected to overcome the careless mistakes of human drivers, which account for 96% of traffic accidents causing injury or death. In the driver model discussed, the value of cognitive reaction time and the braking model are the main issues related to the preventability of collisions with other road users or obstacles. Cognitive reaction time is said to be approximately 0.75 s in the legal system and by national police in Japan, but the true value in real traffic situations is not yet clear. In supreme court judgments, it is said to be unreasonable to take experimental values given by mentally readied research subjects. In this study, cognitive reaction time is measured in real traffic situations, captured as near-miss cases by a twin camera driving recorder. Foot images are captured with a front view simultaneously as the driving behavior of the driver. Cognitive reaction time is measured by frame feed from the beginning point of the hazardous event in the front view to the endpoint when the driver presses the brake pedal in the foot image. The factors that influence cognitive reaction time, such as age, time of day, weather, and traffic situations, are also discussed. 翻訳 |
