Summary
This study addresses the persistent issue of pedestrian fatalities in road accidents, particularly at crossings which should theoretically be safe zones. Motivated by the limitations of passive crash data analysis and the artificiality of driving simulators, the research aims to evaluate how different pedestrian crossing configurations affect driver behavior and perception in a real-world setting. Specifically, it investigates whether traffic calming countermeasures, such as traffic lights and trapezoidal deflections (raised crosswalks), effectively reduce speeding and improve safety by influencing drivers’ cognitive and perceptive processes. The researchers conducted a naturalistic driving experiment on Via Pistoiese, an urban collector road in Florence, Italy, known for a high rate of pedestrian accidents. Thirty-six voluntary participants drove their own vehicles along a 3.8 km section of the road, encountering various crossing types including zebra crossings, signalized crossings, and raised crossings. To capture comprehensive data, the study utilized a VBOX HD2 system to record kinematic data (speed, acceleration, position) and a Pupil Invisible eye-tracker to monitor drivers’ gaze and fixation patterns. The analysis focused on four driving indicators: speed at the crossing axis, speed at the stopping sight distance, speed difference during deceleration, and the distance from the crossing where deceleration began. Data were filtered to exclude instances involving red traffic lights or active pedestrian crossings to isolate driver responses to infrastructure. Statistical analysis was performed using two-way ANOVA to assess the effects of traffic lights and trapezoidal deflections on these driving indicators. The results demonstrated significant differences in driver behavior in response to varying traffic calming measures. Notably, raised pedestrian crossings caused a significant reduction in vehicle speed approaching the crossing. Furthermore, the study found that perceptive countermeasures only influenced driver behavior when the crossing configuration was perceived within the driver’s foveal vision. This indicates that the correct visual identification of the infrastructure is a prerequisite for drivers to adjust their behavior congruently and safely. The analysis confirmed that drivers’ gaze patterns were directly linked to their deceleration behaviors, highlighting the critical role of visual perception in driving performance. The significance of this research lies in its validation of naturalistic driving studies combined with eye-tracking as a robust methodology for assessing road safety interventions. By linking physical infrastructure changes to specific perceptual and behavioral outcomes, the study provides evidence that raised crossings are effective in mitigating speeding. It also underscores the importance of designing countermeasures that are visually salient enough to capture foveal attention, ensuring drivers recognize and respond to safety features. These findings offer practical insights for urban planning and traffic engineering, suggesting that effective pedestrian safety strategies must account for human factors and visual perception to successfully modify driver behavior.
Key finding
Raised pedestrian crossings significantly reduced driver speeds, and behavioral changes in response to perceptive countermeasures occurred only when the crossing configuration was perceived in foveal vision.
