Challenge Problems
Push your limits with advanced challenges
Given an approach with 900 vehicles per hour, how would you assess the need for a rotary versus a traditional traffic light? Provide your rationale based on design principles.
💡 Hint: Consider how traffic interactions are handled differently in each system.
If a rotary’s design permits a weaving width of 15 meters, calculate the maximum weaving traffic flow assuming the average entry and exit widths are 10 meters each.
💡 Hint: Stop and consider the relationship between width and traffic efficiency.
