Influence of Repeated Experience on Unsignalized Intersection Crossing Behavior of Drivers without Right-of-Way

Collisions at intersections account for more than 50 percent of total traffic accidents in Japan [1]. The most common cause of these incidents is human error. Therefore, understanding the nature of driving behavior at intersections is essential for developing and implementing accident prevention measures. This study aimed to examine the influence of a driver's repeated experience with crossing un-signaled intersections without the right-of-way. Specifically we examined the change of start position, identified as a point where drivers step on the gas pedal immediately prior to entering intersections. Also we assessed the relationship between driving behavior at intersections and responses to a Driving Style Questionnaire (DSQ) [2]. Repeated experience often leads to habituation, and driving behavior is no exception to this [3]. For instance, many drivers begin to drive faster on narrow streets as they gain experience [4]. At the same time, there is a real possibility that drivers acquire proficiency through experience. In the interests of improving traffic safety, this study aimed to describe the nature of changes in driving behavior as drivers experience repeated encounters with interactions.
