A new interstate highway is being built with a design speed of 120 km/h. For one of the horizontal curves, the radius (measured to the innermost vehicle path) is tentatively planned as 300 m. The limiting value for coefficient of side friction at 120 km/h is 0.09. What rate of superelevation is required for this curve at the 120 km/h design speed
