Question:
The shape of the most commonly designed highway vertical curve is
The shape of the most commonly designed highway vertical curve is
Show Hint
Parabolic curves are commonly used in highway design for vertical curves due to their smoothness and ease of transition between grades.
Updated On: Jan 2, 2026
- circular (single radius)
- circular (multiple radii)
- parabolic
- spiral
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
The most commonly designed vertical curves for highways are parabolic. This is because a parabolic curve provides a smoother transition between different grades, which is safer and more comfortable for drivers. The other types of curves (circular, spiral) are used less commonly in highway design due to factors such as comfort and ease of construction.
Final Answer: (C) parabolic

- A car is travelling at a speed of 60 km/hr on a section of a National Highway having a downward gradient of 2%. The driver of the car suddenly observes a stopped vehicle on the car path at a distance 130 m ahead, and applies brake. If the brake efficiency is 60%, coefficient of friction is 0.7, driver's reaction time is 2.5 s, and acceleration due to gravity is 9.81 m/s2, the distance (in meters) required by the driver to bring the car to a safe stop lies in the range
