Employing a unique set of traffic signs, this research examines the effectiveness of two versions of the You Only Look Once (YOLO) object detection framework: YOLOv8 and YOLOv9. The aim is to provide a detailed understanding of each version’s strengths and weaknesses in traffic sign detection, with implications for enhancing real-world object detection in dynamic traffic scenarios. Preliminary findings indicate that YOLOv9 outperforms YOLOv8, demonstrating higher precision and F1-score. This highlights YOLOv9’s potential for robust traffic sign detection solutions. Despite assessment, our research represents an essential contribution to the discipline of computer vision including applications to traffic sign recognition. The study’s results offer a useful resource for practitioners and researchers selecting optimal models for similar applications, ultimately contributing to developing smarter and more efficient transportation networks.
