A)should meet the original straight tangentially
B)should meet the circular curve tangentially
C)the rate of increase of curvature along the transition curve should be same as that of increase of super-elevation
D)all of the above

Question

Quizplus · Accepted Answer

A transition curve serves several purposes: it provides a gradual change from a straight path to a curved path, ensuring that the transition meets both the straight and curved paths tangentially. Additionally, it allows for a gradual increase in curvature and super-elevation, making the change smoother for vehicles. Thus, all the statements A, B, and C are correct regarding the purpose and characteristics of a transition curve.
