Andorra's Turbo Roundabouts Cut Travel Times 15% and Boost Safety Despite Driver Confusion

Andorra's turbo roundabouts at KM0 and Prada Casadet continue to show a 15% reduction in travel times, alongside improved safety, though some drivers—particularly visitors—still struggle with the new layout.

David Forné, Secretary of State for Transport and Energy Transition, which oversees the Mobility department, reiterated these benefits in recent statements. He noted that updated signage has boosted traffic flow and eliminated unexpected vehicle crossings, making safety the standout gain. "The best part, beyond the travel time, is safety because you no longer encounter a car crossing your path," Forné said. At Prada Casadet, previously among the nation's most accident-prone sites, no injury-related incidents have occurred since the 3 March launch, with only minor material damage collisions reported and deemed insignificant.

The layout directs straight-bound drivers to the right lane and those turning to the left, enhancing overall fluidity—especially during peak hours—while improving trajectory efficiency. The pilot, intended as a potential permanent fixture, targets only roundabouts with specific traffic patterns suitable for turbo designs, a format used abroad but not invented locally. Officials emphasize that full evaluations remain ongoing.

Recent observations highlight lingering challenges. At midday on a busy day at Prada Casadet, a Spanish-plated vehicle hesitated abruptly in the left lane, meant for turns following the roundabout path, prompting a local van to honk. Traffic police describe initial functioning as "correct" but urge caution pending more data.

Local workers near the site acknowledge the area's past troubles but note persistent confusion among outsiders. Pedro Rodríguez, manager of the Cambalache restaurant, passes twice daily and anticipates issues from foreign plates: "If I see an out-of-country plate, I know they'll cross my path." Sergio Faria, owner of Giro Metal workshop and originally from Lisbon, finds the system straightforward compared to Portugal's demanding Relógio roundabout, yet observes: "People continue doing it wrong."
