1 - Give a horizontal curve with a radius of 450 m, delta angle 35 and the PI station of 15+20, compute the curve data and the station of PT. 2- A 6 horizontal curve covers an angle 68. Determine the radius, the length of the curve and the middle distance from the chord. (Metric units) 3- What super elevation rate would you recommend for a roadway with a design speed of 110 km/hr and the radius of curvature of 480 m? Assume side friction is 0.12. 4- A road is being designed capable of allowing 110 km/hr vehicle speed. The super elevation is 0.06 and the coefficient of side friction is 0.11. Determine minimum radius of curve. 5- The mayor of Jazan wants to erect a large sign welcoming visitors as they enter the city. The road has four 12 ft lanes with 4 ft shoulder. It is also a horizontal curve radius of 1200 ft. The speed limit is 45 mph. How far should the sign be placed from the highway to avoid potential stopping sight distance issues?
