Challenge Problems
Push your limits with challenges.
Question 1
Consider a road where the density increases from 0 to 50 vehicles/km over a span of time. Graph the flow-density curve and identify the peak flow rate based on your assumptions.
💡 Hint: Determine how you would expect flow to behave as density increases.
Question 2
Analyze a scenario where adding an additional lane doubles the vehicle flow. What implications does this have for the flow-density relationship?
💡 Hint: Consider how density and flow interact when infrastructure improvements are made.
