17.2.4. Creeper lane

Try these first

1. 1.

   What is a creeper lane?

   Hint

   Think about why slower vehicles need their own lane.

2. 2.

   When should a creeper lane ideally be introduced?

   Hint

   Consider the speed in relation to the design speed.

3. 3.

   When should a creeper lane be introduced?

   • When speed is above design speed
   • When speed drops to half of design speed
   • When traffic is light

   Hint

   Consider the impact of speed on road flow.

4. 4.

   True or False: Creeper lanes should end abruptly.

   • True
   • False

   Hint

   Think about how vehicles would transition when merging.

5. 5.

   Consider a steep road segment where the design speed is 60 km/h. At what speed would a creeper lane be implemented? Discuss the implications for traffic flow.

   Hint

   Focus on calculating half the design speed.

6. 6.

   Evaluate a scenario where creeper lanes are inadequately designed leading to safety risks. What measures would you recommend to improve the situation?

   Hint

   Think about how to enhance driver visibility and ease of merging.
