Exercise 7 Consider a four lanes highway (a lane width w = 3.6m) on which the design speed is U = 110 km/h. The highway has a change in the direction and a horizontal curve is needed to link the two segments of the highway. The superelevation proposed here is edes = 6%. The highway is normal crown with exc = 2%. 1. What is the minimum curvature Radius Rmin in this case? 2. Suppose in this question that the design radius used is Rdes = 1.5 Rmin. What are the values of the tangent runoff L, and the tangent runout L, if the number of lanes to be rotated are two lanes?
