Summary
This paper addresses the need for accurate simulation tools to estimate the traffic accident reduction effects of Advanced Driver Assistance Systems (ADAS) and Automated Vehicles. Motivated by Japanese government initiatives to promote these technologies, the authors aim to develop a multi-agent simulation that realistically reproduces driver behavior. A critical challenge in such simulations is modeling individual differences among drivers, as real-world driving varies significantly based on personal attributes. The study specifically investigates the validity of a framework that links driver characteristics—such as gender, age, personality, and physiological state—to driving behaviors, using data from controlled experiments. The methodology involves analyzing the relationship between driver attributes and driving behavior using data from 64 participants (young, middle-aged, and elderly males and females). Driver attributes were categorized into three ranks (high, intermediate, low) for "tendency to obey traffic law," "driving skill," and "information processing ability," based on scores from the Driving Style Questionnaire (DSQ) and Workload Sensitivity Questionnaire (WSQ). Participants drove a 1.1 km test route at the Japan Automobile Research Institute under two conditions: normal driving and "rush" driving (simulating urgency). The study measured velocity, acceleration, and control inputs. Additionally, attention function was assessed using the Trail Making Test (TMT) to correlate cognitive performance with age and self-reported attributes. The results indicate that driver attributes significantly influence behavior, but their impact depends on driving conditions. The tendency to obey traffic laws affected travel velocity regardless of the experimental condition, suggesting it is a stable behavioral determinant. In contrast, driving skill primarily affected velocity only during rush driving conditions, implying that skill becomes a differentiating factor under stress or urgency. The study also found that elderly drivers had lower ranks in driving skill and information processing ability, which correlated with longer completion times in the TMT, confirming age-related declines in attention function. Furthermore, the rush condition resulted in a statistically significant increase in average speed (12.6 km/h higher than normal), validating the simulation’s parameter for arousal levels. Male drivers exhibited significantly higher speeds than females only under rush conditions. The significance of this work lies in providing empirical validation for the driver model parameters used in the STREET simulation framework. By demonstrating that specific driver attributes predict behavioral changes under different conditions, the study supports the development of more realistic multi-agent simulations. These simulations are essential for quantitatively predicting the safety benefits of ADAS and automated vehicles, thereby aiding policy-making and technology deployment strategies. The findings highlight the importance of incorporating individual differences, particularly regarding legal compliance and skill under stress, to accurately estimate accident prevention effects.
