Challenge Problems
Push your limits with challenges.
Question 1
A city intersection has a saturation flow rate of 1750 vehicles/hour. During peak hours, the cycle time is 70 seconds with an effective green time of 40 seconds. Calculate the lane capacity and discuss its implications on intersection design.
💡 Hint: Follow the capacity formula to derive your answer.
Question 2
In a new traffic signal design, loss time during signal change is projected to be 5 seconds. How would you account for this in your lane capacity calculation if the green time remains unchanged?
💡 Hint: Always consider how lost time affects total available time for vehicles.
