Summary
This study investigates the impact of Unmanned Aerial Systems (UAS), or drones, on driver performance, addressing a critical gap in transportation safety literature. The research is motivated by the increasing use of UAS for efficient traffic data collection, such as continuous speed monitoring for speed limit setting, which offers advantages over traditional point-speed capture methods. However, flying UAS near roadways introduces potential external visual distractions. Since eye glances away from the roadway for two seconds or more double crash risk, understanding how UAS altitude and the presence of drone operators affect driver behavior is essential for developing safe regulations. The researchers employed a combined approach consisting of a literature review and a full-immersion driving simulator experiment. The simulator study evaluated driver performance metrics—specifically visual attention, speed, and lateral position—in response to varying UAS heights and the presence of drone pilots on the roadside. The experimental design controlled for other variables such as traffic volume and weather. Data were collected using eye-tracking devices to measure visual distraction and vehicle telemetry to monitor speed and lane offset. The study also included a static evaluation to assess participant familiarity with UAS and their attitudes toward drone usage near roadways. The findings indicate that UAS operations significantly distract drivers. Participants exhibited greater visual distraction when both the drone and its pilot were present compared to scenarios with only the drone. Specifically, in 11% of all analyzed situations, participants were critically visually distracted, defined as maintaining a continuous glance at the drone or pilots for two seconds or longer. The study also found that the level of distraction varied based on the drone's lateral proximity to the roadway, with closer traversal resulting in higher distraction levels. Additionally, the literature synthesis confirmed that UAS usage in transportation is expected to increase, highlighting the urgency of understanding these safety implications. The significance of this research lies in its provision of evidence-based recommendations for policymakers regarding UAS regulations near roadways. By quantifying the distraction risks associated with specific UAS operational parameters, the study helps balance the benefits of efficient data collection with roadway safety. The results suggest that regulations should account for the heightened distraction caused by the presence of drone operators and the critical nature of prolonged visual glances. This work supports the development of standards that allow for the innovative use of UAS in traffic engineering while mitigating the risk of distraction-related crashes.
Key finding
Drivers experienced significantly higher visual distraction and critical glances when both the drone and its pilots were present compared to when only the drone was visible.
