Driver performance research focuses on studying the factors that affect the ability of individuals to safely operate a vehicle. This includes examining variables such as reaction time, attention, decision-making skills, physical and mental capabilities, and the impact of distractions or stress on driving behavior. Research in this area aims to improve road safety by understanding how to optimize driver performance and reduce the risk of accidents. Studies may use simulators, real-world driving assessments, or other methods to evaluate driver performance in various scenarios.
