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.

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 5° curve (measured at the centerline of the inside lane) is being designed for a highway with a design speed of 100 km/h. The curve is on a 2% upgrade, and driver reaction time may be taken as 2.5 seconds. What is the closest any roadside object may be placed to the centerline of the inside lane of the roadway while maintaining adequate stopping sight distance?
