Question 1
What does Greenberg’s model predict about speed as density approaches zero?
- Speed tends to zero
- Speed tends to infinity
- Speed remains constant
💡 Hint: Think about the extremes of the model.
Question 2
Is it true that Greenberg's logarithmic model can accurately predict speeds at all densities?
- True
- False
💡 Hint: Consider the limitations discussed.

Challenge Problems
Push your limits with challenges.
Question 1
Calculate the speed when the free flow speed is 50 km/h, jam density is 150 vehicles/km, and density is 75 vehicles/km using Greenberg’s model.
💡 Hint: Use the logarithm rules to compute.
Question 2
Discuss the implications of the model predicting infinite speed at zero density. How can this affect traffic planning?
💡 Hint: Consider how planners use models for predictions in real contexts.
