Challenge Problems

Push your limits with challenges.

Question 1

Consider a scenario where a link's initial flow is 50 vehicles with a free flow time of 10 minutes. If the link's capacity is 100 vehicles, calculate the expected travel time using the cost function if α = 0.15 and β = 4.0. What implications does this have for traffic management?

💡 Hint: Apply the formula correctly, paying attention to parameters.

Question 2

Devise a traffic assignment strategy based on an increasing flow pattern observed in a city. How would you incorporate the Link Cost Function to optimize routes and minimize congestion?

💡 Hint: Think about how dynamic assignments adapt to changing conditions.
