Study on Novice Drivers' Fixation Features under Different Car-Following Risk Levels
Through early interviews 22 common traffic scenes were found and leveled by questionnaires. Six scenes of low-risk, medium risk and high risk were selected and implemented in the simulation software using the software of Creator, Vega, C++, etc. Simulation experiments were conducted to analyze the novice drivers fixation features under different levels of risk based on the designed real car simulation platform. The results showed that both novice and experienced drivers saccade times are more than 3 times greater than the fixation times, suggesting that drivers visual search are found mainly in saccadic movement other than watch movement. In potentially dangerous environment, experience drivers always reduce fixation time and increase saccade time to make early warnings of danger that may arise, while novice drivers saccade time and fixation time are relatively stable. Novice drivers concern more about the dashboard regardless of the level of risk in any scenarios comparatively. In the three levels of risk conditions, novice drivers watching areas are more concentrate, namely, their fixation area mostly focus on some certain areas while ignoring other areas, such as rearview mirror and traffic signals.
