Question
E]
A simple circular horizontal curve connects the following two bearings:
• N 75° W
• S 85° E
The station number at the point of intersection (PI) is 120+50.00, and the radius of the curve is
3000ft.
(a). Calculate the degree of curve, curve length, and tangent length.
(b). Determine the station numbers at PC and PT.
(c). A sight obstruction is located at a distance of 10.00ft from the center of the inside lane of this
curved two-lane two-way highway section, what is the available sight distance on the curve?
