3 cards from this section. Quick, good the night before a test.
What does the Link Cost Function represent?
Think about how flow impacts travel dynamics.
Define the term free flow travel time.
Consider what flow conditions are required for 'free flow'.
What does the variable 't' represent in the Link Cost Function?
Think about what is being measured over a link.
Is the following statement true or false: 'Travel time decreases as flow increases.'
Consider congestion effects on travel times.
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?
Apply the formula correctly, paying attention to parameters.
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?
Think about how dynamic assignments adapt to changing conditions.
