Abstract

OBJECTIVE The aim of this work is to assess how drivers adapt their driving speed as a self-regulation mechanism when driving under the influence of alcohol (DUIA), and the influence of alcohol consumption, visual performance, road complexity, and personal traits. METHOD Thirty one volunteers took part in the study. All of them underwent three experimental sessions: Baseline (no alcohol), Alcohol 1 (low-moderate dose), and Alcohol 2 (moderate-high dose). Vision was tested by means of contrast sensitivity and retinal straylight. Driving performance was assessed using a driving simulator. The difference between the driving speed and the speed limit was calculated in 10 road scenarios of different complexity. RESULTS Drivers adapted their driving speed less (i.e., drove faster) in Alcohol 1 condition compared to Alcohol 2 (p = 0.007). This indicate that participants felt more confident under the influence of a low-moderate dose of alcohol. Participants with better contrast sensitivity drove faster (p = 0.021). The complexity of the road and other factors such as driving experience, gender, or DUIA frequency, also influenced speed choice. CONCLUSIONS Drivers under the influence of a low-moderate dose of alcohol seem to be less aware of the risk. Contrast sensitivity is a good predictor of the speed choice when DUIA. A better understanding of drivers' behavior under the influence of substance use may be useful to adjust and improve the traffic laws and driving regulations.

酒精对驾驶员速度管理的影响：视觉表现和道路复杂性的影响。

目的本研究旨在评估驾驶员在酒后驾驶（DUIA）时如何调整其驾驶速度作为一种自我调节机制，以及酒精消耗量、视觉表现、道路复杂性和个人特征的影响。所有志愿者都进行了三次实验：基线（不饮酒）、酒精 1（低-中剂量）和酒精 2（中-高剂量）。通过对比敏感度和视网膜杂光测试视力。驾驶性能通过驾驶模拟器进行评估。结果与酒精 2 相比，在酒精 1 条件下，驾驶者调整驾驶速度的程度较低（即开得更快）（p = 0.007）。这表明受试者在中低剂量酒精的影响下更有信心。对比敏感度较高的参与者驾驶速度更快（p = 0.021）。道路的复杂程度和其他因素，如驾驶经验、性别或 DUIA 频率，也会影响速度选择。对比敏感度可以很好地预测司机在酒后驾车时的速度选择。更好地了解司机在药物使用影响下的行为可能有助于调整和改进交通法规和驾驶规范。

期刊介绍： The Journal of Studies on Alcohol and Drugs began in 1940 as the Quarterly Journal of Studies on Alcohol. It was founded by Howard W. Haggard, M.D., director of Yale University’s Laboratory of Applied Physiology. Dr. Haggard was a physiologist studying the effects of alcohol on the body, and he started the Journal as a way to publish the increasing amount of research on alcohol use, abuse, and treatment that emerged from Yale and other institutions in the years following the repeal of Prohibition in 1933. In addition to original research, the Journal also published abstracts summarizing other published documents dealing with alcohol. At Yale, Dr. Haggard built a large team of alcohol researchers within the Laboratory of Applied Physiology—including E.M. Jellinek, who became managing editor of the Journal in 1941. In 1943, to bring together the various alcohol research projects conducted by the Laboratory, Dr. Haggard formed the Section of Studies on Alcohol, which also became home to the Journal and its editorial staff. In 1950, the Section was renamed the Center of Alcohol Studies.
