Multiple-vehicle Trajectory Planning Framework Considering Vulnerable Road Users

This study aims to address the challenge of real-time trajectory planning for connected and automated vehicles (CAVs) while considering vulnerable road users (VRUs) in the environment. The problem lies in efficiently planning trajectories for CAVs in the presence of unpredictable VRUs, ensuring safety and avoiding crashes. The solution involves modeling the decision-making processes of CAVs and VRUs through game theory, incorporating the uncertainty of VRUs' motion using confidence intervals, and designing efficient heuristic algorithms for real-time problem solving. The project's expected outcomes include a technical paper describing the developed trajectory planning framework, along with simulation videos showcasing its effectiveness. This proposal seeks to fill a research gap by exploring novel solutions for this complex problem and contribute to the field of CAV operations. The proposed framework's concepts and validation methods are intended for educational purposes and potential practical implementation in future CAV operations.
