. A simple circular curve exists with a degree of curve D = 10, and

e= 0.10. A structure is proposed on land on the inside of curve. Assume the road is on level grade. Determine: (a) The radius of the curve (b) The current maximum safe speed of the curve (c) The minimum distance allowable between the proposed structure and the centerline of the curve such that the current maximum safe speed of the curve would not need to be reduced
