Understanding driver distractions in fatal crashes: An exploratory empirical analysis.

Area of Science:

• Transportation Safety
• Human Factors in Driving
• Road Accident Analysis

Background:

• Driver distraction is a growing concern in transportation safety due to increasing in-vehicle technologies.
• Sources of distraction are multifaceted, encompassing both internal and external factors.
• Understanding these distractions is crucial for developing effective safety interventions.

Purpose of the Study:

• To categorize distraction enablers and examine their fundamental characteristics.
• To investigate the effect of various distraction sources on fatal crashes, considering driver age and sex.
• To identify trends in distraction-affected fatal crashes and specific demographic vulnerabilities.

Main Methods:

• Literature review to categorize distraction sources into six subcategories.
• Analysis of external and internal distraction characteristics and influences.
• Statistical tests including Tukey test, chi-square, Nemenyi post-hoc, and Marascuilo procedure were employed.

Main Results:

• Inner cognitive inferences were the primary driver of distraction.
• Young drivers exhibited a higher likelihood of distraction from in-vehicle technology.
• Female drivers within the young demographic were more susceptible to technology-related distractions than males.
• Drivers over 80 years old were most impacted by inner cognitive interferences.

Conclusions:

• Cognitive load and in-vehicle technology are significant factors in driver distraction across different age groups.
• Targeted interventions may be needed for young female drivers concerning technology use.
• Older drivers require specific attention regarding cognitive interference mitigation strategies.
