Tracing Methamphetamine abuse in under-treatment drivers: How biomechanical and oculomotor features help detect at-risk drivers?
🤖 AI Summary
This study addresses a critical gap in identifying driving risks among individuals recovering from methamphetamine dependence by integrating eye-tracking and Kinect-based biomechanical sensor data within a driving simulator environment. It proposes, for the first time, a multimodal feature-driven k-nearest neighbors (KNN) classification model embedded within an advanced driver assistance systems (ADAS) real-time analytical framework to automatically detect high-risk driving behaviors in drivers with a history of stimulant abuse. The model achieves a classification accuracy of 90%, offering a robust technical approach and empirical foundation for proactive traffic safety interventions targeting this vulnerable population.
📝 Abstract
While the detrimental impacts of driving under the influence of stimulants such as methamphetamine are well-documented, the driving performance of individuals currently under-treatment has received considerably less attention. This study compared the behavior of individuals with a history of stimulant abuse (across two distinct treatment phases) with a control group of healthy drivers using a driving simulator. Oculomotor and biomechanical data were continuously collected via an eye-tracker and a Kinect sensor, respectively. These parameters were utilized to train a K-Nearest Neighbors (KNN) classification model designed to detect high-risk behavioral patterns in drivers undergoing methamphetamine rehabilitation. Through the evaluation of various feature combinations and neighborhood configurations, the optimized model successfully discriminated between normal drivers and those with a history of abuse with an accuracy of 90%. Detecting at-risk drivers through technologies embedded in Advanced Driver Assistance Systems (ADAS) by continuously monitoring physiological and behavioral parameters, facilitates a proactive safety strategy. Issuing real-time alerts to the driver, passengers, and external monitoring networks can ultimately mitigate the risk of traffic collisions.
