Young drivers' perceptions of risk and difficulty: Day versus night

Area of Science:

• Traffic Psychology
• Human Factors Engineering
• Road Safety Research

Background:

• Inexperienced drivers face elevated crash risks, especially at night.
• Limited research exists on day-night differences in driver risk perception.
• Previous studies focused on vehicle speed, neglecting situational complexity.

Purpose of the Study:

• To investigate day-night differences in drivers' perceived risk and difficulty.
• To explore how situational complexity, beyond vehicle speed, influences these perceptions.
• To analyze the relationship between risk and difficulty ratings across diverse driving scenarios.

Main Methods:

• Exploratory study with 62 participants (aged 16-30) grouped by driving experience.
• Quantitative and qualitative analyses of continuous risk and difficulty ratings.
• Presentation of 14 video clips depicting varied road-traffic situations (day/night, different locations, varying complexity and speed).

Main Results:

• No significant differences in ratings based on participant experience or age groups.
• Night driving scenarios were rated significantly higher for risk and difficulty than day scenarios.
• Situational complexity and location significantly influenced ratings; vehicle speed was not the primary determinant.

Conclusions:

• Driver perceptions of risk and difficulty are significantly higher at night.
• Road-traffic situation complexity, including visibility and predictability of other road users, is crucial for risk assessment.
• Further research is needed on how information processing demands influence driver perceptions.
