The correlation between driving risk and visual attention when using smartphones while driving in novice drivers

Area of Science:

• Traffic Safety
• Human-Computer Interaction
• Cognitive Psychology

Background:

• Despite restrictions, smartphone use while driving is prevalent due to enforcement limitations.
• Novice drivers often have lower safety awareness and higher inherent risk.
• Understanding the impact of smartphone use on novice driver behavior is crucial for accident prevention.

Purpose of the Study:

• To analyze how different smartphone usage methods affect novice drivers' visual attention and driving risks.
• To investigate the scientific relationship between visual attention changes and driving performance.
• To identify specific smartphone tasks that pose the greatest risk to novice drivers.

Main Methods:

• A driving simulation study involving 45 novice drivers.
• Four task conditions: hand-held calls, hands-free calls, texting, and no smartphone use.
• Eye-tracking technology to measure visual attention (blink duration, fixation, saccades).
• Driving simulation scenarios to assess driving functions (speeding, lane deviations, collisions).

Main Results:

• Significant alterations in visual attention metrics (eye blinks, fixations, saccades) were observed during smartphone use.
• Smartphone use correlated significantly with increased driving risks (speeding, lane/road edge excursions, collisions).
• Texting while driving demonstrated the highest increase in accident risk, even with speed reduction.

Conclusions:

• Smartphone use, particularly texting, significantly impairs novice drivers' visual attention, leading to increased accident risks.
• Changes in visual attention directly correlate with degraded driving performance and higher collision likelihood.
• Findings underscore the need for targeted interventions to improve novice drivers' traffic safety attitudes regarding smartphone use.
