Summary
This study investigates how individual attentional characteristics and age influence driver distraction caused by roadside advertisements. Motivated by the need to ensure road safety for users with varying cognitive capabilities, the research addresses two primary issues: establishing empirical criteria for limited attention performance using the Test2Drive psychological testing system, and determining the impact of distracting stimuli on driving performance in simulator scenarios. The authors posit that while older drivers may compensate for declining bottom-up attention with experience, they remain vulnerable to salient distractors like billboards. The research employed a two-part methodology. First, the authors analyzed data from approximately 17,652 professional drivers aged 18–85 using the PUT (Psychological Unit Test) from the Test2Drive battery. This test measures visual inspection speed and accuracy through a conjunctive search task, requiring subjects to identify specific targets among distractors. Based on this large dataset, the study established cut-off points for impaired attentional performance, identifying drivers under 40 as having optimal performance. Second, a simulator experiment was conducted with 60 drivers (aged 20–60) divided into three age groups. Participants performed two tasks: the Three Vehicle Platoon Task (3VPT), requiring constant speed and distance maintenance, and the Lane Change Task (LCT). Distraction was manipulated by displaying a red dot on roadside billboards for either 1 or 2 seconds, or not at all. The results from the large-scale analysis confirmed that attentional performance, specifically processing speed and accuracy, significantly decreases with age. In the simulator experiment, no significant effects were found in the LCT paradigm. However, in the 3VPT paradigm, significant interactions were observed. Drivers with poor attentional performance exhibited greater speed variability, indicating instability in maintaining consistent speed. Additionally, mean speed was slightly lower when the distracting stimulus was exposed for two seconds. The study found that attention accuracy moderated the effect of distraction, with drivers having attentional malfunctions showing more pronounced issues with maneuver accuracy and speed control. The significance of these findings lies in the confirmation that drivers with limited attentional performance are more susceptible to distraction from roadside advertisements. Although the effects were less strong than expected, likely due to the small sample size and the simplicity of the simulator tasks, the study proves that salient distractors negatively impact driving performance, particularly for those with attentional deficits. The authors conclude that road environments should be designed to minimize such distractors to ensure safety for all road users, regardless of age or cognitive ability. Furthermore, the study highlights the importance of psychological assessment for drivers of all ages, as attentional performance varies significantly within age groups.
