Positional Commonality of Behavior Selection by Skilled Drivers in Complex Driving Situations for Driver Assessment

To evaluate unsafe driving, it is essential to identify the driving behavior characteristics of skilled drivers in identical situations as a standard for safe driving.Previous studies on skilled drivers have reported individual differences in behavior depending on specific conditions or indices.These variations pose challenges in understanding driving behavior characteristics in complex driving scenarios.In this study, we focus on probabilistic decision-making theory and propose a method to extract the positional commonality of skilled drivers' driving behavior selection in scenarios requiring multiple driving behaviors.Utilizing data collected through self-localization technology, which accurately determines the vehicle's position, we analyzed the driving behavior selection characteristics of skilled drivers in complex driving situations.The results revealed that the driving behavior of skilled drivers in complex scenarios varies across three distinct zones.The extracted characteristics functioned as a safe driving index in evaluating unsafe driving, confirming the validity of the proposed method.
