Abstract:
This paper proposes a method that leverages Visible Light Communication (VLC) to enhance traffic signal efficiency and optimize vehicle trajectories at urban intersections. By integrating VLC-based localization with learning-based traffic signal control, the system enables real-time communication between vehicles and infrastructure, facilitating data collection and coordinated decision-making. Designed for multi-intersection environments, the approach reduces pedestrian and vehicle waiting times while improving overall safety. Its adaptive framework dynamically adjusts to different traffic patterns within signal phases, ensuring flexibility and efficiency. Cooperative mechanisms regulate traffic flow across intersections, enhancing road network performance. Evaluated using the SUMO urban mobility simulator, the system demonstrates significant reductions in waiting and travel times. Additionally, an agent-based scheme optimizes traffic signal scheduling based on VLC-driven interactions. The proposed approach is decentralized, scalable, and well-suited for real-world traffic management applications.
