Kehätiet
Kehätiet, meaning "ring roads" in Finnish, are a common feature in urban planning, particularly in Finland and other Nordic countries. These roads are designed to encircle or partially encircle a city or a significant urban area, serving to divert traffic away from the city center. The primary purpose of kehätiet is to improve traffic flow, reduce congestion within the core of the city, and provide alternative routes for through traffic.
By channeling traffic around residential and commercial areas, kehätiet aim to enhance the quality of life
The construction and design of kehätiet vary depending on the size and density of the urban area
