2.37. Give any five general requirements of a transition curve.

Try these first

1. 1.

   What is a transition curve?

   Hint

   Think about how roads change direction.

2. 2.

   Name one requirement of a transition curve.

   Hint

   Consider the factors affecting vehicle navigation.

3. 3.

   What is the purpose of a transition curve?

   • To connect two straight roads
   • To smoothly transition between straight and curved roads
   • To increase road width

   Hint

   Think about why sharp transitions are problematic.

4. 4.

   True or False: Super-elevation is not important in transition curves.

   • True
   • False

   Hint

   Recall the role of banking in curves.

5. 5.

   Design a transition curve for a roadway with a speed limit of 100 km/h. Calculate the necessary length and radius.

   Hint

   Refer to engineering design tables for specific calculations.

6. 6.

   Examine the consequences of a straight edge connecting two curves without a transition. What safety measures could be implemented?

   Hint

   Consider the role of design in mitigating hazards.
