Reaction Time Variability Association with Safe Driving Indexes
Naturalistic Driving Study (NDS) encompasses data analysis of driver performance in normal, impaired and risky traffic situations. This work investigates results of a cognitive assessment tests targeting different human factors including visual field, reaction speed, driving behavior and personality traits of drivers in a NDS. Frequency of being involved in Near Miss event (fnm) and Frequency of committing Traffic Violation (fv) are defined as indexes of safe driving in this work. Inference of association shows statistically significant correlation between Standard Deviation of Reaction Time (\u3c3RT) and both safe driving indexes fnm and fv. Causal relationship analysis excludes age as confounding factor as variations in behavioral responses is observed in both younger and older drivers of this study
