Overview

• The static 120 km/h speed limit on the AP-7 in Catalonia has been replaced with a dynamic AI-controlled system that adjusts in real time based on traffic, weather, and road conditions.
• The pilot project, currently deployed near Tarragona, aims to enhance traffic safety, reduce accidents, cut CO₂ emissions, and lower fuel consumption.
• Digital signs display updated speed limits, which can drop to as low as 80 km/h when risk factors such as poor visibility or high traffic density are detected.
• Critics have raised concerns about the system's accuracy, potential driver confusion, and the high costs of maintenance and operation.
• If successful, the system could be expanded to other regions in Spain, marking a significant step in the adoption of intelligent transport systems across Europe.
