2.32. Draw a neat sketch of a reverse curve provided to join two parallel straights.

Try these first

1. 1.

   What is a reverse curve?

   Hint

   Think about how curves can connect two lines.

2. 2.

   Name one element needed for sketching a reverse curve.

   Hint

   These are parts of the sketch!

3. 3.

   What is a reverse curve?

   • A straight line
   • Two curves in opposite directions
   • A sharp angle

   Hint

   Think about how curves connect two lines.

4. 4.

   True or False: The radius of a curve does not affect its sharpness.

   • True
   • False

   Hint

   A smaller radius usually means a sharper curve.

5. 5.

   Design a reverse curve connecting two parallel roads. Given the two radii and the angle of deflection, calculate the necessary dimensions.

   Hint

   Use the formula for the length of an arc.

6. 6.

   Evaluate how changing the radius of one arc in a reverse curve affects the overall road safety and driving experience.

   Hint

   Consider real-life scenarios like highway turns.
