Analysis on Driver’s Physiological and Eye Movement Characteristics under Alcohol Effect

Abstract

Drink-driving has a significant impact on road traffic safety. Based on the choice of driver’s physiological and eye movement characteristics indicators, this study compared driver's skin electricity change characteristics was compared under different alcohol intake, heart rate scatter diagram was used to establish the Poincare section, and driver’s physiological characteristics under alcohol effect were analyzed. Driver’s fixation, saccade and blink were compared under different alcohol intake to study the change of some characteristics. On the basis of the recovery experiment of drivers’ physiological and eye movement characteristics after drinking, this study gave the elimination time under alcohol effect of physiological and eye movement characteristics then revealed the change law of the driver’s physiological and eye movement characteristics under alcohol effect. Results show that alcohol effect elimination time can be determined by analyzing driver’s physiological and eye movement characteristics indices, which is useful for mastering the reasonable driving time after drunk.
