| Abstract: | • Various machine learning based systems have been used to detect drink driving. • Neural networks were most commonly employed in reviewed studies. • Vehicle dynamics and control inputs were the most common input variables. • Significant heterogeneity between studies limits generalisability of results. • Future research must standardise testing and focus on practical input variables. Introduction : Alcohol-impaired driving is a persistent global public health concern, with limited recent progress in reducing its impact on roads, highlighting the need for innovative approaches. The increasing adoption of machine learning (ML) has led to its application in detecting alcohol-induced driving impairment. This systematic review examines and synthesizes existing research that leverages ML utilizing in-vehicle sensors to detect alcohol-impaired driving, with a focus on the ML models employed and the input variables analyzed. Method: Studies were included if they applied ML techniques to detect alcohol-induced driving impairment using in-vehicle sensor data. The literature search was conducted in various academic databases and was supplemented by citation-based article retrieval. Primary outcomes of interest were the ML models employed and input variables. A risk of bias assessment was performed to evaluate study reliability and validity. Results: There were 26 relevant studies identified. The reported classification accuracy was consistently high, with median accuracy of 89%. Although the majority of studies were performed using driving simulators, there was significant heterogeneity with respect to other important study characteristics. The most common input variables used related to vehicle dynamics and control inputs, and the most common ML models implemented were neural networks. Conclusions and Practical Applications: This systematic review highlights limitations in the current literature related to significant heterogeneity in study characteristics and methodological issues in many identified studies. While some promising results were observed, further research is required to determine the optimal approach, particularly with respect to finding the most compatible and practical ML models and input variables for reliable detection.
