Abstract
In this study, we examined the influence of drinking alcohol on driving behavior to detect drunk driving from the a driver's driving behavior. We conducted an experiment on driving under the influence of alcohol using a driving simulator, compared the distribution trend of driving behavior with and without drinking alcohol, and analyzed how the influence of alcohol affects driving behavior. The results indicated that the influence of drinking alcohol on driving
operation and vehicle behavior appeared in lateral indicators such as steering wheel angle, not longitudinal indicators such as accelerator operation and speed. Moreover, a significant regression equation was derived by focusing on these indicators and using multiple regression analysis with breath alcohol concentration (BrAC) as the dependent variable. When the presence or absence of alcohol consumption was determined from the estimated BrAC, with the true positive detection rate set to about approximately 70%, the false positive rate was about approx
