AI-powered predictive traffic system combining live camera streams, recorded video archives, and YOLO/OpenCV vehicle detection to forecast congestion levels and optimize signal timing. Input feeds flow through vehicle detection, tracking, and density analysis modules that classify traffic as low, medium, or high and calculate adaptive signal timings. This architecture demonstrates end-to-end computer vision pipeline design for smart city applications, reducing congestion and improving traffic flow efficiency. Fork and customize this diagram on Diagrams.so to adapt detection models, add real-time data sources, or integrate with traffic management systems. The modular three-layer design allows independent scaling of detection, analysis, and visualization components.
