Measuring car drivers' skills--an economist's view

Area of Science:

• Traffic Safety Research
• Behavioral Psychology
• Driver Training Analysis

Background:

• Assessing the impact of driver training on behavior is crucial for road safety.
• Previous studies suggest a complex relationship between driver education and accident rates.
• Understanding driver risk perception is key to effective safety interventions.

Purpose of the Study:

• To develop a model for evaluating driver behavior and skills.
• To analyze the influence of specific training courses on driving performance.
• To investigate the paradoxical increase in accident rates following slippery surface driving courses in Norway.

Main Methods:

• Development of a novel model to quantify driver behavior and skills.
• Analysis of driver behavior data in the context of training interventions.
• Examination of a Norwegian investigation into slippery surface driving courses.

Main Results:

• The developed model successfully defines and quantifies driver skills.
• Slippery surface driving courses in Norway were associated with a significant increase in traffic accidents.
• Drivers undergoing these courses showed a greater reduction in perceived risk than in objective skidding risk.

Conclusions:

• Driver training models can effectively assess skill development and training impact.
• Slippery surface courses may inadvertently increase risk-taking due to altered risk perception.
• Future driver training should address risk perception alongside technical skills to enhance road safety.
