Over-speeding trend across self-reported driving aberrant behaviors: A simulator study

Area of Science:

• Psychology
• Traffic Safety Research
• Human Factors

Background:

• Self-reported aberrant driving behaviors are a concern for road safety.
• The Manchester Driver Behavior Questionnaire (DBQ) is a common tool for measuring these behaviors.
• Virtual driving simulations offer a controlled environment to assess actual driving performance.

Purpose of the Study:

• To investigate the relationship between self-reported aberrant driving behaviors (using the Italian DBQ) and actual driving performance in a virtual simulation.
• To focus on over-speeding as a key performance indicator.
• To explore the utility of a driving simulator combined with self-report measures.

Main Methods:

• An Italian sample of 79 participants (aged 18-35) completed the Italian DBQ.
• Participants engaged in a simulated driving task using a moped simulator.
• Cluster analysis of kinematic data identified 'Prudent' and 'Imprudent' driver groups.

Main Results:

• Self-report responses on the DBQ positively correlated with performance variables like acceleration, speed, and over-speeding.
• The 'Imprudent' driver cluster exhibited higher speeds and acceleration compared to the 'Prudent' cluster.
• MANOVA results supported the integrated approach, confirming the relevance of DBQ, especially for Ordinary Violations and Lapses.

Conclusions:

• The study validates the use of the DBQ in conjunction with driving simulators to assess aberrant driving behaviors.
• The findings support the effectiveness of simulators in detecting actual driver performance and over-speeding.
• Results can inform the development of targeted interventions and training programs to enhance road safety.
