A Study on the Relationships between Unsafe Driving Behaviors and Driver’s Inner Factors When Entering a Non-signalized Intersection

Abstract

By conducting an interview survey using actual driving videos, we found that normal drivers without the right of way have incorrect awareness of the potential hazards when entering a non-signalized intersection. We also conducted a questionnaire survey in which subjects answered a sequence of their driving behaviors concerning when and how they make safety checks and operate the accelerator and brake pedals. We revealed the characteristics of unsafe driving behaviors of normal drivers through comparison with the desirable ones of skilled drivers. We extracted 12 inner factors that cause deviations from desirable driving behavior and revealed the relationships between the inner factors and four elemental driving behaviors. Finally, we discussed the possibility of applying the models to a concrete method of driver safety education.
