2.29. Show the various elements of a simple circular curve on a neatly drawn sketch.

Try these first

1. 1.

   Define the term 'Circular Curve'.

   Hint

   Think about how roads curve.

2. 2.

   What is the significance of the Point of Intersection (PI)?

   Hint

   Relate it to road turns.

3. 3.

   What defines a circular curve?

   • A straight line
   • A curve connecting two tangents
   • A zigzag path

   Hint

   Think about how curves are used in roads.

4. 4.

   True or False: The Point of Tangent is where the curve begins.

   • True
   • False

   Hint

   Remember the starting point of a curve.

5. 5.

   Design a circular curve with given parameters: radius of 100m and deflection angle of 60 degrees. What components must be included in your diagram?

   Hint

   Focus on the layout of the curve and accurately labeling each part.

6. 6.

   If a circular curve has a radius of 500 m, calculate the theoretical deflection angle needed to transition smoothly between two straight paths intersecting at 30 degrees.

   Hint

   Use your understanding of geometry to approach this problem.
