A. A curving roadway has a curve with a radius of 640 m. The superelevation has been set at 5% and the coefficient of side friction is found to be 0.20. In addition, the traffic engineer has designed the speed as 125 km/hr, and the angle is 74°. i. Explain whether this speed will provide a safe vehicle operation or not? ii. Find middle ordinate iii. Curve length iii. Tangent Length v. Sketch the curve elements with all values B. Describe the major elements that geometric design of highways deals with? (write between 100-150 words)
