On August 12, as thousands prepared to witness a rare total solar eclipse, Asturias and the Dirección General de Tráfico (DGT) rolled out a system to monitor traffic flows to 16 of the region’s most visited beaches. Authorities acted on forecasts of exceptionally high visitor numbers along the coast, estimating between 400,000 and 1.5 million additional journeys across Spain for the event.
The system combines ground-based sensors and artificial intelligence-powered cameras, feeding live data into the Digital Twin of Asturias’ territory. The platform pulls information from multiple sources to give authorities an up-to-date picture of mobility patterns. They can use it to detect congestion and make real-time decisions about access and parking.
Technology in Action
Unlike traditional traffic monitoring, the new approach pairs sensor networks with AI-driven visual analysis. Data is processed centrally and shared with the DGT’s management systems, helping authorities respond quickly to bottlenecks or incidents. Variable message panels on highways and basic roads can alert drivers to delays and restrictions, or direct them to alternative routes before they reach affected areas.
This pilot is among the first operational uses of Asturias’ Digital Twin, a project announced earlier in 2024 to modernize traffic management in coastal zones. Its deployment during the eclipse put the system to a real-world test, measuring its ability to handle sudden surges in visitor numbers, especially where parking and road capacity are limited.
Direct Communication with Drivers
Local authorities use the sensor data, which is also integrated into the DGT’s national traffic management network. Alerts can then be sent immediately through established channels, including roadside panels and digital platforms, as well as the DGT’s 011 phone service. During the eclipse, authorities also shared updates on social media and navigation apps, and through radio broadcasts.
The initiative reflects a broader shift toward connected mobility in Spain, where the DGT is investing in digital infrastructure to improve road safety and efficiency. Technologies such as the DGT 3.0 platform and real-time incident reporting increasingly shape how traffic information reaches the public.
Lessons for the Future
The eclipse provided a unique stress test, and the government of Asturias sees wider potential for the system. Officials plan to assess its effectiveness in future special operations, including emergency response and civil protection, as well as tourism management. Monitoring and responding to rapid changes in traffic demand could prove valuable during summer peaks and festivals, or when unexpected events occur.
Asturias has been developing its connected mobility strategy since at least 2024, with plans to digitalize road networks and install tunnel sensors, while building real-time data transmission capabilities. Collaboration with the DGT and national transport authorities is seen as basic to scaling these innovations beyond the pilot phase.
As the region reviews the results from August 12, the experience may offer a model for how Spanish coastal destinations manage mobility challenges in the years ahead.
