A horizontal curve offers a switch between two tangent strips of roadway. It allows a vehicle to negotiate a turn at a steady rate rather than a sharp cut. The design of the curve is reliant on the projected design speed for the roadway, as well as other factors including drainage and friction. See more Horizontal curve has several geometric properties.
