Challenge Problems
Push your limits with challenges.
Question 1
A rotary has an entry radius of 10m. If the exit radius is 1.5 times this entry radius, what should the exit radius be?
💡 Hint: Multiply the entry radius by 1.5.
Question 2
Discuss the implications of having a very small weaving length at a rotary. How might it affect traffic safety and flow?
💡 Hint: Consider what happens when vehicles are too close together.
