<html><body>EcoTraffic is an EdgeAI smart traffic system that optimizes urban traffic flow in Barcelona in real time.Three intelligent nodes communicate via MQTT:- Vehicle Node (Arduino UNO Q + webcam): detects cars using YoloX-Nano running locally, calculates waiting times and queue length, and sends smart alerts only when anomalies are detected.- Traffic Light Node (Arduino UNO Q + webcam): receives alerts, detects cars and pedestrians locally, calculates a dynamic demand score and decides when to change the traffic light cycle. Emergency vehicles get immediate green light- Dashboard: visualizes everything in real time with an interactive map, global metrics and CO₂ saved.All inference runs locally on Arduino UNO Q — no cloud, zero latency, under 50€ per node. Privacy by design — images never leave the device.Estimated impact: 30% reduction in waiting times, 18% reduction in CO₂ emissions.</body></html>
