The Horizon Europe research project metaCCAZE has recently released a new Blog Post authored by Evi Koliou on AI and Smart Cities. As stated, AI-driven solutions can transform urban environments, since smart traffic control systems are no longer a futuristic concept but a present reality. These AI-driven systems optimise traffic flow, reduce congestion, and cut down emissions. By leveraging connected vehicle data and digital twins—technology that simulates real-world scenarios—we can develop road safety strategies that save lives.
