Summary
This final report details research conducted by The Ohio State University and North Carolina A&T State University to develop computational models of driver behavior for both human and autonomous vehicles. The primary objective was to understand how multi-agent models can inform the design of optimized autonomous systems, particularly for Advanced Driver Assistance Systems (ADAS) and pre-crash safety scenarios. The project aimed to quantify human driving behavior to improve risk assessment, trajectory prediction, and control strategies in mixed traffic environments involving human drivers, semi-autonomous vehicles, and fully autonomous convoys. The research employed two parallel methodological tracks. Ohio State University researchers utilized Hidden Markov Models (HMM) and Hybrid-State Systems (HSS) to model decision-making and trajectory prediction, specifically for lane-change and intersection approach scenarios. They developed classifiers to distinguish between normal and dangerous driving behaviors using naturalistic driving data. North Carolina A&T researchers focused on Support Vector Machines (SVM), Takagi-Sugeno fuzzy models, and personalized driving models. They also developed a simplified matrix formulation for the sensitivity analysis of HMMs to improve computational efficiency. Both groups integrated these behavioral models into control frameworks, including Model Predictive Control (MPC) for vehicle convoys and variational approaches for trajectory planning. Key findings demonstrated that HMM-based classifiers could effectively estimate driver status and predict trajectories for lane-changing vehicles, with dangerous maneuvers exhibiting larger trajectory variances than normal ones. Integrating these predictions into MPC controllers for vehicle convoys resulted in smaller velocity and spacing fluctuations compared to conservative controllers, improving stability during cut-in events. At NC A&T, SVM-based models achieved over 97% accuracy in estimating driver intentions at intersections, outperforming HMMs in generalization. Additionally, a personalized highway driving system successfully adapted to individual driver aggression levels, maintaining safety while respecting user preferences. The proposed simplified matrix formulation for HMM sensitivity analysis reduced computational complexity from quadratic to linear time, enabling more efficient real-time processing. The significance of this work lies in its contribution to the development of safer and more efficient autonomous vehicle systems. By accurately modeling human behavior and integrating these models into control algorithms, the research provides a foundation for ADAS and autonomous vehicles to anticipate human actions, reduce crash risks, and operate smoothly in mixed traffic. The personalized driving models also address the need for autonomous systems to accommodate diverse driving styles, enhancing user acceptance. Furthermore, the improved computational methods for model sensitivity analysis support the real-time implementation of complex behavioral models in vehicle control systems.
