AI总结:

本研究开发了基于车载驾驶员监控摄像头的机器学习酒驾检测系统,在30人参与的模拟器研究中验证了其检测酒驾的有效性,为预防酒精相关伤害。

摘要:

过量饮酒会导致伤残和死亡。数字化干预是促进行为改变、从而预防酒精相关伤害的有效手段,尤其是在驾驶等关键场景中,这需要获取人体血液酒精浓度(BAC)的实时信息。本文开发了一种车载机器学习系统,用于预测临界BAC临界水平。该系统利用全球众多国家强制要求安装的驾驶员监控摄像头实现功能。我们在一项干预型模拟器研究中招募了30名参与者对系统进行评估。该系统能可靠检测出受酒精影响的驾驶行为(受试者工作特征曲线下面积[AUROC]为0.88),也能检测出BAC超过世卫组织建议的0.05g/dL限值的驾驶行为(AUROC为0.79)。模型分析显示,系统的判断依赖于与饮酒相关的病理生理效应。据我们所知,我们是首个严格评估驾驶员监控摄像头用于酒驾检测的研究团队。研究结果凸显了驾驶员监控摄像头的应用潜力,可支持开发下一代酒驾干预交互系统,预防酒精相关伤害。

英文摘要:

Excessive alcohol consumption causes disability and death. Digital interventions are promising means to promote behavioral change and thus prevent alcohol-related harm, especially in critical moments such as driving. This requires real-time information on a person's blood alcohol concentration (BAC). Here, we develop an in-vehicle machine learning system to predict critical BAC levels. Our system leverages driver monitoring cameras mandated in numerous countries worldwide. We evaluate our system with n=30 participants in an interventional simulator study. Our system reliably detects driving under any alcohol influence (area under the receiver operating characteristic curve [AUROC] 0.88) and driving above the WHO recommended limit of 0.05g/dL BAC (AUROC 0.79). Model inspection reveals reliance on pathophysiological effects associated with alcohol consumption. To our knowledge, we are the first to rigorously evaluate the use of driver monitoring cameras for detecting drunk driving. Our results highlight the potential of driver monitoring cameras and enable next-generation drunk driver interaction preventing alcohol-related harm.
