Transition curves are provided on the approach to horizontal curves in order to __.
A. reduce jerk to allowable levels
B. increase jerk to allowable levels
C. minimize the length of the horizontal curve
D. simplify the laying out and construction of the horizontal curve
Answer:A
Transition curves are provided on the approach to horizontal curves in order to __.
A. reduce jerk to allowable levels B. increase jerk to allowable levels C. minimize the length of the horizontal curve D. simplify the laying out and construction of the horizontal curve
Explanation: The radius of the transition curve reduces from infinity at the point of intersection to the desired radius of the circular curve.
