Try these first

1. 1.

   Define a simple curve.

   Hint

   Think about the shape and its endpoints.

2. 2.

   What is a transition curve?

   Hint

   Consider its purpose in easing curves.

3. 3.

   What defines a simple curve?

   • A curve with varying radius
   • A constant radius arc
   • A straight line connection

   Hint

   Focus on the features of the curve.

4. 4.

   True or False: Reverse curves can enhance safety on high-speed roads.

   • True
   • False

   Hint

   Consider how abrupt turns affect safety.

5. 5.

   Hint

   Consider the balance between speed and curvature.

6. 6.

   Evaluate the implications of using reverse curves in a residential area. What would be the potential hazards?

   Hint

   Think about visibility and speed in tight spaces.
