Abstract

The objective of this research was to study the performance of young novice male drivers in a driving simulator after they were administered different doses of alcohol (placebo: 0 g/kg; medium dose: 0.75 g/kg; high dose: 1 g/kg) during the blood alcohol concentration (BAC) ascending and descending periods. The high dose of alcohol produced an average peak BAC of 74±5.477 mg/100 ml at 30 min after administration, and the medium dose produced an average peak BAC of 47.714±17.68 mg/100 ml at 10 min after administration. Compared with the placebo, the drivers' performance under the high dose of alcohol was characterised by more abrupt steering manoeuvres, a greater average speed, and a greater offset from the lane centre. The drivers were more timid under the medium dose administration. The study on driver behaviour plays an important role on constructing the early warning model, so as to put forward the corresponding intervention measures of unsafe driving behaviour and improve vehicle safety in reducing accidents due to drinking and/or drunk driving on public roads.

驾驶模拟器中酒精影响下血液酒精浓度上升和下降期间驾驶性能的比较

本研究的目的是研究年轻男性新手驾驶员在驾驶模拟器中被给予不同剂量的酒精后的表现(安慰剂:0 g/kg;中剂量:0.75 g/kg;高剂量:1 g/kg)在血液酒精浓度(BAC)上升和下降期间。高剂量酒精在给药后30 min产生的平均峰值BAC为74±5.477 mg/100 ml，中剂量酒精在给药后10 min产生的平均峰值BAC为47.714±17.68 mg/100 ml。与服用安慰剂的司机相比，高剂量酒精下的司机表现出更突然的转向动作、更高的平均速度和更大的偏离车道中心的程度。中剂量组小鼠胆子更小。驾驶员行为研究对于构建预警模型，提出相应的不安全驾驶行为干预措施，提高车辆安全性，减少公共道路上酒后驾驶事故具有重要作用。

期刊介绍： The IJVS aims to provide a refereed and authoritative source of information in the field of vehicle safety design, research, and development. It serves applied scientists, engineers, policy makers and safety advocates with a platform to develop, promote, and coordinate the science, technology and practice of vehicle safety. IJVS also seeks to establish channels of communication between industry and academy, industry and government in the field of vehicle safety. IJVS is published quarterly. It covers the subjects of passive and active safety in road traffic as well as traffic related public health issues, from impact biomechanics to vehicle crashworthiness, and from crash avoidance to intelligent highway systems.
