Summary

This research brief addresses the critical safety issue of distracted driving, which contributes to driving instability and crashes resulting in injury and loss of life. The primary motivation is the need for early detection of driver distraction to provide timely feedback and warnings. The study aims to develop a framework for detecting driver impairment by analyzing real-time volatilities derived from extensive biometric data, vehicle kinematics, and roadway environment information. The methodology involves collecting and analyzing data from multiple sources, including driver gaze data, vehicle kinematics indicators, and external factors such as interactions with surrounding traffic. The conceptual framework focuses on detecting deviations from regular driving events and linking these deviations to safety-critical events. The study specifically explores the association between the duration of distracted driving, driving errors, violations, and safety-critical outcomes. Additionally, the research investigates how inference-based statistical models and machine learning algorithms can enhance emerging driver assistance systems in automated vehicles, with a specific focus on distracted driving scenarios. The findings indicate that drivers involved in crashes and near-crashes exhibited longer durations of distraction compared to baseline drivers. Furthermore, drivers involved in safety-critical events demonstrated higher instability in their driving behavior relative to baseline drivers. These results highlight a clear correlation between extended distraction periods, increased driving instability, and the occurrence of safety-critical events. The significance of this work lies in its potential to improve traffic safety by developing more intelligent and forgiving vehicle automation features. By leveraging inference-based statistical models and machine learning algorithms, the project aims to enhance driver assistance systems in automated vehicles. The findings support the development of systems capable of detecting driver impairment through real-time analysis of volatilities, thereby providing early warnings and feedback to mitigate the risks associated with distracted driving. This approach contributes to the broader goal of creating safer, more responsive automated vehicle technologies that can effectively address the challenges posed by driver distraction.

Key finding

Drivers in crashes and near-crashes were distracted for longer and showed higher driving instability than drivers in baseline events.
