Integration of a Real-time Traffic State Estimation and a Decentralized Game-Theoretic Traffic Signal Controller

This project proposes to enhance a decentralized traffic signal controller based on a Nash Bargaining game-theoretic framework, integrating a Kalman filtering (KF) algorithm for real-time traffic state estimation. By combining KF with the traffic signal controller, the project aims to optimize signal phasing sequences at intersections based on turning movements and traffic density, thereby reducing queue lengths, delays, and emissions. The approach involves traffic data collection through loop detectors and probe vehicle data, and it will address saturation flow rates for shared lanes. This integration intends to achieve efficient system performance across varying probe vehicle market penetration levels, ultimately providing a robust solution for improved traffic flow and reduced environmental impact at intersections.

The study expects to demonstrate reduced congestion and environmental impact at signalized intersections by optimizing traffic flow, vehicle delay, and queue length. The results will quantify the improved performance of the integrated KF and game-theoretic model across various levels of data availability, offering an adaptable approach for real-world applications in eco-driving and traffic management.
