Simulator-Based Study of the Response Time and Defensive Behavior of Drivers in Unexpected Dangers at an Intersection
Intersection traffic accidents account for a substantial percentage of all traffic accidents, and they may lead to a high rate of fatalities. In this study, we aim to determine drivers’ responses when faced with unexpected dangers by obtaining data on drivers’ behavioral characteristics. We explored how drivers respond to intersection dangers in a simulated environment. Data including reaction times, vehicle data, occurrence of accidents, and ways to avoid accidents of 155 participants were analyzed. The results revealed a significant difference in steering angle, and speed between men and women, as well as in brake reaction time between 20s and 40s. A significant difference was observed in perception time, and brake reaction time depending on the occurrence of accidents. The findings of this study are expected to be used for predicting the reaction times and vehicle data, and determining the causes of traffic accidents.
