Naples' ring road has been certified by Italy's transport ministry as the country's first Smart Road. Sensors, traffic monitoring and car-to-road communication herald the mobility of tomorrow. Italy's smart mobility revolution starts in Naples. Tangenziale di Napoli is in fact the first road infrastructure in the country to have obtained official Smart Road certification from the Ministry of Infrastructure and Transport. The recognition confirms the adoption of advanced technologies for infrastructure monitoring, intelligent traffic management and real-time communication between the road and connected vehicles, including self-driving ones. It is a milestone that projects Italy into a new era of mobility, turning one of the main urban arteries in the South into a national model of innovation. The project that transformed Tangenziale di Napoli The initiative is the result of collaboration between Tangenziale di Napoli, a company of the Autostrade per l'Italia Group, the Ministry of Infrastructure and Transport, the National Centre for Sustainable Mobility (MOST) and Movyon, the technology hub of the Aspi Group. The aim was clear: to make the infrastructure capable of collecting, processing and sharing real-time information to improve the safety, efficiency and sustainability of traffic flows. Today Tangenziale di Napoli is one of the most advanced Italian laboratories dedicated to connected and cooperative mobility. The three features that define a Smart Road To obtain certification, Tangenziale di Napoli had to meet three key requirements laid down by the regulations. Intelligent traffic monitoring Sensors capable of collecting continuous data on traffic have been installed along the entire network. The information is processed by advanced traffic models that support operators in the control centre in their decisions on how to manage traffic. This approach makes it possible to intervene in a preventive way, reducing congestion and critical issues before they turn into emergencies. Real-time weather monitoring and hydrogeological
