Summary

This study investigates the safety implications of drone operations near roadway infrastructure, specifically addressing the lack of empirical data regarding how drones distract drivers. As drone usage for commercial and recreational purposes expands, there is a critical need to define safe lateral distances and encroachment zones to prevent visual and cognitive distractions that could degrade driving performance. The research was motivated by existing regulatory gaps and anecdotal concerns that drones flying near traffic create unsafe conditions, yet no specific guidance existed on how proximity, flight patterns, or environmental context influence driver attention. To address this, the researchers conducted a driving simulator experiment using a randomized, partially counterbalanced factorial design. The study evaluated three independent variables: lateral offset (distance of the drone from the roadway edge at 0, 25, and 50 feet), flight path (takeoff, scanning, or racing), and land use (urban vs. rural environments). A total of 54 participants were recruited, but 24% experienced simulator sickness, resulting in a usable sample of 39 participants. The experimental setup utilized a high-fidelity driving simulator equipped with a mobile eye-tracking system to measure visual attention metrics, including total fixation duration and dwell duration, while also monitoring lane position and vehicle velocity. The results indicated that drone operations significantly impacted driver visual attention. The frequency and length of glances at drones increased as the lateral offset decreased, meaning drivers looked more often and longer at drones closer to the roadway. Drone operations were found to be more distracting in rural environments compared to urban ones. Crucially, the study identified a potential for unsafe glances—defined as dwell durations exceeding two seconds—at all tested lateral offsets (0, 25, and 50 feet). However, the highest frequency of these unsafe glances occurred at the 0-foot offset, where the drone was directly adjacent to the roadway. Additionally, some participants exhibited lane deviations and velocity changes in reaction to drone encounters, particularly when the drone was close to the road. The significance of these findings lies in providing empirical evidence to support the development of safety regulations and administrative rules for drone operations near highways. The study suggests that optimal encroachment avoidance zones may need to differ between urban and rural areas, with rural settings posing a higher distraction risk. These results offer state Departments of Transportation, such as the Oregon Department of Transportation, data-driven insights to establish safety protocols and best practices for both their own drone operations and the regulation of public drone use, thereby mitigating the risk of drone-induced driving distractions.

Key finding
