32. What is the term used to describe the transition zone between normal cross slope and full super-elevation on a highway curve?
- Spiral curve
- Critical section
- Superelevated section
- Transition curve
Answer
The correct answer is: D) Transition curve
Explanation
The transition curve gradually introduces super-elevation, minimizing abrupt changes in cross slope for smoother vehicle transition.
