Summary
This thesis investigates the impact of out-of-vehicle distractions on the hazard anticipation and vehicle control of novice versus experienced drivers. Motivated by crash statistics indicating that external distractions contribute to nearly 30% of crashes and the increasing complexity of driving environments, the study addresses a gap in literature where in-vehicle distractions have been extensively studied, but external distractions remain less understood. Specifically, it examines whether experienced drivers, who typically exhibit better situational awareness with internal tasks, are similarly vulnerable to external distractions like roadside signs or billboards. The research employed a driving simulator study comparing younger novice drivers (ages 16–18, licensed <6 months) with older experienced drivers (ages 21+, licensed >5 years). Participants navigated a virtual environment while performing secondary external search tasks, such as scanning roadside signs. The experimental design included control sections and scenarios with passive hazards (parked cars) and active hazards (obscured pedestrians). Data collection utilized an eye tracker to record glance durations and directions, alongside vehicle metrics for speed maintenance and lane deviation. The study aimed to determine if long glances away from the forward roadway during external tasks compromised safety performance differently across age groups. The results indicated that both novice and experienced drivers took equally long glances away from the forward roadway when attending to external tasks. These extended glances negatively impacted hazard anticipation performance for both groups. Regarding vehicle control, long glances significantly impaired the lane maintenance ability of younger novice drivers compared to their experienced counterparts. However, speed maintenance abilities were not significantly affected for either group. Despite differences in lane control, the study concluded that both age groups face an elevated risk of crashing when attending to tasks outside the vehicle, as the long glances compromise the ability to predict and avoid hazards. The significance of these findings lies in challenging the assumption that experienced drivers are less susceptible to external distractions. While experienced drivers may maintain lane position better than novices during such distractions, their hazard anticipation is equally degraded. This suggests that the perceived safety of using peripheral vision for lane keeping during external glances may provide a false sense of security, as critical safety information is missed. The study underscores that external distractions pose a substantial risk to all drivers, regardless of experience, highlighting the need for interventions that address out-of-vehicle attention lapses.
Key finding
External distractions cause equally long glances away from the roadway for both novice and experienced drivers, impairing hazard anticipation for both groups but significantly degrading lane maintenance only for novice drivers.
