2.7.3. Characteristics of a vertical curve

Try these first

1. 1.

   What is the purpose of a vertical curve in road design?

   Hint

   Think about how changes in elevation affect driving.

2. 2.

   Name two types of vertical curves.

   Hint

   Consider how they relate to elevation changes.

3. 3.

   What is a vertical curve primarily used for?

   • To enhance visibility and comfort
   • To increase road width
   • To lower costs

   Hint

   Consider the impact of changing grades on visibility.

4. 4.

   True or False: All vertical curves are circular.

   • True
   • False

   Hint

   Think about the shape that fits best for gradual slopes.

5. 5.

   Design a vertical curve that connects a gradient of +3% to -2% over a distance. Determine the proper length and assess the safety considerations necessary.

   Hint

   Calculate the total change and apply the rate of change formula.

6. 6.

   Evaluate the safety risks if a vertical curve is significantly shorter than recommended standards, particularly for a high-speed road area.

   Hint

   Focus on the importance of gradual changes for road users.
