Challenge Problems

Push your limits with challenges.

Question 1

Given a free-flow speed of 70 km/h, a jam density of 250 vehicles/km, and n = 1.2, calculate the speed at a density of 125 vehicles/km.

💡 Hint: Substitute the values into the model equation to find v.

Question 2

Discuss the implications of applying Pipes’ Generalized Model with n = 0.8 in a busy urban area. How might this affect traffic management strategies?

💡 Hint: Consider how gradual changes in speed could influence traffic flows and management systems.
