c) (R + S) tan θ/2 + L/2. The total tangent length of a curve is the distance along the curve between the points where the curve intersects the tangents that define the beginning and end of the curve. In a transition curve, which is a curve used to connect two straight sections of a road or other transportation facility, the total tangent length is given by the formula (R + S) tan θ/2 + L/2, where R is the radius of the main curve, θ is the angle of deflection, S is the shift, and L is the length of the transition curve. The radius R and the shift S are used to determine the position of the curve relative to the straight sections, while the angle of deflection θ and the length L are used to define the shape and size of the curve. The total tangent length of the curve is the sum of the length of the main curve and the length of the transition curve, and is used to determine the length of the roadway or other transportation facility required to accommodate the curve.
