Problem 7 A simple curve having a radius of 150 m. connects two tangents that meet with an intersection angle of 55° 30'. The curve is to be shifted by moving the forward tangent 20 m. outward to a position parallel to its original position. Find the radius of the new curve if the P.C. shall be retained. Answer: R₂ = 231.64 m.
A horizontal curve is being designed for a new two-lane highway (12-ft lanes). The PC is at station 150+50, design speed is 55 mi/h, and a superelevation of 0.08 fuft is to be used. If the central angle of the curve is 40 degrees, design a curve for the highway by computing the minimum radius and stationing of the PI and PT??

An arterial road is to be connected to a frontage road by a reverse curve with parallel tangents. The distance between the centerline of the two tangent section is 18 m. The PC of the curve is located at station (38+125.31) and the central angle of each of the component curves is 25°. Determine the radius of each of the two curves in the reverse curve if they have the same radius and central angle. Determine the station of PT. Determine the maximum speed to be allowed on this curve if the superelevation rate is 8%.

A. Reversed curve with diverging tangents is to pass through three lines to form a center line of a proposed road. the first line AB has a bearing of N 88° E. and a distance of 125 m., BC has a bearing of N 60° E and a distance of 350 m., while on that of CD has a bearing of S 40° E and a distance of 305 m. If the first tangent has a distance of only % of the common tangent measured from the point of intersection of the first curve determine the radius of the curves and station of PT if PC is 12 + 350

Determine the values and stationing (sta. PT) for a compound curve to be placed on an exist loop of a freeway. The stationing of the loop construction will start at the point the taper departs the freeway with a station of 10+00. The Pl of the compound curve will begin 2,700ft after the taper starts.
