This paper aims to evaluate the impact of vehicle characteristics on risky driving behavior, focusing on harsh acceleration and deceleration events, within the framework of the H2020 project i-DREAMS. Given the substantial impact of human factors on safe driving behavior, the i-DREAMS project developed a ‘Safety Tolerance Zone (STZ)’ to define the boundary where self-regulated control can be maintained safely. The study utilizes a CatBoost model to analyze data collected from a naturalistic driving experiment with 48 drivers and 4922 trips in total, conducted in three phases: baseline monitoring, post-trip interventions, and a gamification process. The goal is to understand how different vehicle attributes affect aggressive driving behavior under varying conditions. The results indicate that certain vehicle characteristics significantly influence the frequency of harsh events, with the intervention phases showing an impact on driver behavior. Specifically, older vehicles and those with higher engine capacity and horsepower are more likely to engage in acceleration events, where the phase of the experiment and the vehicle’s engine capacity have an impact on the existence of the deceleration events. These findings underscore the importance of considering vehicle attributes in designing effective safety interventions and highlight the potential of post-trip feedback to enhance road safety.
