Abstract: In recent years, Smart Cities have become a focal point for integrating advanced technologies and intelligent systems to create sustainable urban environments. A key issue in these cities is reducing emissions, and smart traffic lights have emerged as an important tool in addressing this challenge. This work builds on a previously proposed system designed to reduce pollution through smart traffic lights, which was initially limited to three-way intersections and tested on a single traffic signal. We extend the system to manage various types of signalized intersections and evaluate its performance across multiple intersections in a city. Our findings show that smart traffic lights can reduce pollution even without coordination between traffic lights and vehicles.
