tvåfältsväg

Tvåfältsväg refers to a type of road with two traffic lanes, one in each direction. This is a common configuration for roads of varying capacities, from rural routes to major arterial streets within urban areas. The design typically includes a center line to separate opposing traffic flows.

In many countries, a tvåfältsväg is the most basic form of a two-lane highway. It can be found in both rural and suburban settings. The speed limits and road characteristics can vary significantly depending on the specific road and its intended use. Some tvåfältsvägar are undivided, meaning there is no physical barrier or median separating the lanes of opposing traffic. In such cases, a painted line is used for separation.

The capacity of a tvåfältsväg is generally lower than roads with multiple lanes in each direction or divided highways. Factors such as road width, shoulder presence, and traffic volume influence its efficiency. Upgrades from a tvåfältsväg can include widening, adding passing lanes, or converting it to a four-lane road or a divided highway to handle increased traffic demand and improve safety. The term emphasizes the fundamental layout of having a single lane for travel in each direction.
