Comparative analysis of drivers' vital parameters across varied driving scenarios and experience levels: A pilot study

Introduction

This pilot study explores the vital physiological parameters of 12 car drivers with varying levels of experience, categorized into experienced, middle-experienced, and novice groups, across different driving scenarios. The study addresses the need to understand how different levels of driver expertise and diverse driving conditions influence key physiological responses.

Methods

Drivers' heart rate variability (HRV), respiratory rate (RR), skin temperature (Temp), and heart rate (HR) were monitored during four distinct scenarios: 1) At-rest (stationary conditions), 2) Normal weather during peak hours (regular traffic), 3) Rainy weather during peak hours (adverse weather and traffic), and 4) Non-peak hours (off-peak traffic). Data were collected within the urban intercity of Budapest using a real-world driving loop, providing a realistic environment for assessment. Statistical analysis included descriptive statistics, violin plots for parameter comparison, one-way ANOVA for scenario transitions per driver group, and heatmaps for f-values and percentage changes.

Results

Significant differences were observed in the physiological responses of drivers across scenarios and expertise levels, with novice drivers showing the most variation. The findings underscore the interaction between driver competency, environmental conditions, and experience level, highlighting the importance of these factors in influencing drivers' physiological states.

Conclusions

This study introduces a novel approach to evaluating vital parameters in drivers, laying the groundwork for future research, especially concerning older experienced drivers compared to young novice drivers. The results suggest that targeted interventions, informed by these assessments, are essential for enhancing driver safety and performance in urban traffic settings.
