Kiertoliittymän

Kiertoliittymän is a type of intersection located in Finland and other countries particularly in Europe. The name is translated to "roundabout" in English, referring to its circular or elliptical design. This type of intersection consists of a circular road with one or more lanes, where incoming traffic must navigate around a central island.

Kiertoliittymän is often used to improve traffic flow and reduce congestion at busy intersections. The central island separates incoming traffic streams, preventing the possibility of conflicting traffic flows. Unlike traditional intersections, Kiertoliittymän intersections do not have traffic lights, and drivers navigate through the roundabout by yielding to traffic already in the circle.

The decision to implement a Kiertoliittymän often depends on factors such as traffic volume, safety, and economic considerations. In the design process, traffic engineers and planners consider the number of lanes, pedestrian crossings, and motorway connections to optimize traffic movement. Proper signing is also important to help drivers navigate through the roundabout effectively.

Kiertoliittymän has been widely adopted in Finland and other European countries, with benefits including reduced congestion, improved air quality, and increased road safety. However, it may present challenges for some drivers, particularly those from areas where roundabouts are less common.
