Niveles de alcohol en la sangre y desviación de la línea en conductores estudiados en simuladores: un metaanálisis

Abstract

IntroductionDriving under the influence of alcohol increases the risk of traffic accidents and road accident. However, it is not clear to what extent the presence of alcohol in the blood can divert a driver of the lane. ObjectivesTo determine the minimum concentration of alcohol in the blood that must be reached to alter the driving ability in people and define what skills are affected more quickly in the deviation of the lane test. MethodSystematic review of the literature in eight databases, limited to publications of the last ten years (1999–2009) and articles in which the assessment was made through simulators and concentrations of alcohol in the blood were measured. ResultsOf all the subgroups studied, it is clear that persons with any alcohol consumption tend to drift over the line more than people who have not consumed. Among the drivers who had alcohol in the blood, there was only a slight difference between the deviations from the line of those with levels greater or less than 0.05 (0.65 vs. 0.78). ConclusionsIn all the endpoints was demonstrated that, regardless of the amount of alcohol in the blood, a driver with any alcohol use tend to deviate from the lane. Overall we can say that the deviation of the line becomes a very sensitive evidence of alcohol use.
