This study investigates the impact of driving aids, specifically a Waze navigation application, on driver gaze behavior and attention to road signs. Using the advanced Pupil Labs’ Pupil Invisible eye-tracking system, we conducted experiments to monitor drivers’ visual attention in two distinct scenarios: driving without aids and driving with the Waze navigation application active. A total of 10 participants with varied driving experience completed a predefined urban and suburban route designed to include multiple road signs crucial for safe driving decisions. The gaze data collected revealed notable differences in visual behavior across scenarios. Drivers with assistance exhibited longer gaze fixations on some road signs, however, more road signs (35 versus 31) showed attention decrease. Statistical analysis confirmed these observational trends, highlighting significant reductions in visual engagement with road signs when Waze was utilized. While such aids potentially enhance driving comfort and reduce cognitive load, the diminished visual attention to road signage raises concerns regarding situational awareness and reliance on technological assistance. Given the influence of driving aids on driver attention patterns, it is essential to review and update driver training programs to ensure they adequately prepare drivers to maintain situational awareness and effectively manage reliance on technological assistance.
