17.3.1. Type of Summit Curve

Try these first

1. 1.

   What type of curve is preferred in summit curves for road design?

   Hint

   Consider the type of curve most commonly associated with simple geometric shapes.

2. 2.

   Why is sight distance important in road design?

   Hint

   Think about how visibility affects driving safety.

3. 3.

   What is the preferred type of curve used in summit curves?

   • Circular
   • Parabolic
   • Linear

   Hint

   Think about the characteristics of different curve types.

4. 4.

   True or False: Stopping sight distance and overtaking sight distance are the same.

   • True
   • False

   Hint

   Consider the context of each distance's application.

5. 5.

   Calculate the stopping sight distance for a vehicle moving at 60 km/h, considering a reaction time of 2 seconds.

   Hint

   Convert speed from km/h to m/s for calculations.

6. 6.

   Discuss the effect of improper summit curve design on traffic flow and safety.

   Hint

   Think about how changes in road design impact driving behavior and safety.
