A horizontal curve with a 300 intersecting angle on a two-lane highway with 12-ft has a 60 mph design speed. The radius for the horizontal curve has been set to 1,250 ft. The PI is located at station 85 + 29.14 and the normal crown on the tangent is 2%. Determine:
a) Tangent to Spiral (TS) station,
b) Spiral to Curve (SC) station,
c) Curve to Spiral (CS) station, and d) Spiral to Tangent (ST) station.

A single-lane racetrack is being constructed with a 150 mph design speed. A curve on this track has a radius of 4500 ft, central angle of 30 degrees, and a PI located at station 150+40. If the coefficient of side friction is 0.3, what superelevation is required for safe vehicle travel at the design speed? Also, determine the length of the curve and station of the PC and PT.

ou are asked to design a horizontal curve for a two-lane road. The road has 12-ft lanes. Due to expensive excavation, it is determined that a maximum of 35 ft can be cleared from the road’s centerline toward the inside lane to provide for stopping sight distance. Also, local guidelines dictate a maximum superelevation of 0.08 ft/ft. Determine the design speed for this curve (mph)?

A horizontal curve of radius 5620 ft is designed for 60 mph. The roadway is a 4-lane undivided highway with 12-ft lanes. A tree is located on the inside of the curve only 42 ft from the center of the road. Does it pose a stopping sight distance problem for the drivers travelling at the design speed? Show all supporting calculations.

A horizontal curve on a two lane road is 175 ft long and has a radius of 500 ft to the center of the road. There is a tree 24 ft from the edge of the road in the middle of the curve. The lanes of the road are 12 ft wide each. What is the sight distance available through this curve? Recommend a maximum safe speed limit (within 5 mph) for this curve.
