- Abstract
- The presence of stationary emergency vehicles on high-speed roadways poses heightened safety risks, and driver compliance with Move Over laws remains inconsistent nationwide. In recent years, digital alert systems, integrated into widely used navigation applications and in-vehicle platforms, have emerged as a potential countermeasure to improve driver awareness and safety. However, limited research has examined the effectiveness of these systems in real-world environments, particularly when combined with traditional visual emergency warnings. To address this gap, two field experiments were conducted in Illinois under multiple operational scenarios involving emergency vehicles and digital alert technologies. High-resolution helicopter-based aerial videography was used to capture detailed vehicle trajectories, offering a unique opportunity to evaluate driver speed adjustments and lane-changing behavior under varying alert conditions. This study offers an empirical investigation of the impacts of digital alerts on driver behavior and compliance with the Move Over law. The findings of this study support transportation agencies and technology developers in designing integrated warning systems to enhance roadway safety.
