Challenge Problems

Push your limits with challenges.

Question 1

Design a rotary for a suburban area where the approaching traffic volume is moderate. Discuss how you would determine the entry and exit radii based on expected speed limits and pedestrian traffic.

💡 Hint: Consider ratios and pedestrian flow discussed in the text.

Question 2

Analyze the relationship between the entry and exit radii in a busy urban rotary and propose measurements based on the design requirements of reducing speed and accommodating heavy traffic.

💡 Hint: Look at the problem from both a safety and flow perspective.
