Minimum Radius of Horizontal Curve| Stations of PC and PT of Horizontal Curve
In this video, we are going to learn how to calculate the minimum radius of the horizontal curve from superelevation and we will also learn how to calculate the stations of PC and PT of horizontal curve.
Question: Consider a four-lane highway (2 lanes in each direction and no median) which has a horizontal curve. Each lane is 12 ft wide, and the design speed is expected to be 65 mph, and the super-elevation is 6%. The central angle of the curve is 60 degrees. The station of PI is 305+10. Determine.
The minimum radius for this curve
