Nighttime driving is undoubtedly correlated with risky driving behaviors and is often considered as a risk exposure indicator that affects both accident probability and accident severity. The objective of the present study is to investigate the association between nighttime driving and young drivers’ behavior and safety in an urban driving simulator environment. An experimental process on a driving simulator was carried out, in which 35 participants drove under different driving conditions (low/high traffic, daytime/nighttime conditions) in an urban environment. Then, linear regression statistical modelss were calibrated to investigate the impact of nighttime driving on the mean speed and on the mean reaction time. Moreover, in order to examine the influence of nighttime driving on accident probability, binary logistic method was used. Results indicate that, within the examined driving simulator environment, nighttime driving is associated with an increase in mean speed and mean reaction time, resulting in a statistically significant increase in the probability of being involved in a crash. These findings quantify the effects of nighttime driving on young drivers’ behavior and safety under controlled urban simulation conditions and may provide preliminary evidence for future research and discussions on nighttime road safety interventions.
