A turbo-roundabout is a relatively new type of roundabout, which provides a spiraling flow of traffic, requiring drivers to choose their direction before entering the roundabout. Professor L.G.H. Fortuijn first introduced it the late 1990's as a safer and more efficient alternative to the standard multi-lane roundabouts.

turbo roundabouts are adaptable to the U.S. context, providing an effective roundabout solution for higher-volume intersections. The goal of this document is to synthesize existing published resources (e.g., reports, papers, presentations, videos, and tools) on

describe the characteristics of turbo roundabouts, highlighting the design and traffic control features, operational capabilities, and potential safety benefits of these roundabout alternatives. 1 A 2 x 2 roundabout is characterized by two entry lanes approaching two circulating lanes.

Learn about the flexibility and unique features that make TORUS the most sophisticated and dynamic roundabout design software. As turbo-roundabouts spread throughout the world as an alternative to standard multi-lane roundabouts, new design software will be needed to handle the growing demand.

Turbo roundabouts are multi-lane roundabouts with spiral road markings and with entry and circulating lanes separated by raised lane-dividers. The Turbo Roundabout was introduced in the Netherlands to solve capacity and safety issues that often occur in …

The turbo roundabout directs vehicles to approach more radially, significantly reducing the distance a vehicle must clear when entering. In some cases, the turbo roundabout has been shown to decrease crashes by 50% compared to traditional roundabouts.

Jan 9, 2024 · Research suggests turbo roundabouts lead to fewer conflicts (down 50% compared to two lane alternatives) and increased capacity (45% more traffic can be handled on average). Moreover, they serve to decrease congestion and vehicle speeds alike.

prompted implementation of turbo roundabouts • Describe the geometric and operational characteristics of turbo roundabouts • Identify public outreach strategies for turbo roundabouts • Locate available resources to inform turbo roundabout implementation in the U.S.

With various tools – raised or non-raised lane dividers, simple lane markings, – a turbo-roundabout is channeling vehicle movements in a narrower area than a regular multi-lane roundabout. In other words, vehicles' driving speed on the circulatory lane is lowered to guarantee maximum safety.

Turbo roundabouts decrease congestion and increase safety, which is ever important in a popular and touristic place such as the Okanagan Valley. Why does Canada need Turbo roundabouts? It all comes down to safety. Roundabouts in general …
