Question

Perpendicular offset from the junction of a transition curve and circular curve to the tangent is equal to:

• A. 1 times shift
• B. 0.5 times shift
• C. 2 times shift
• D. 4 times shift

Hint:

Offset = 4 × shift in transition curve design.

Answer 1

The Correct Option is D

The perpendicular offset from the tangent to the circular curve through the transition curve is 4 times the shift. This relationship comes from the geometry of transition curves.
