Challenge Problems
Push your limits with challenges.
Question 1
For a road with a free flow speed of 80 km/h and jam density of 250 vehicles/km, calculate the maximum possible flow. Then, find the traffic flow when the density is 100 vehicles/km.
💡 Hint: Use Greenshield's equations for your calculations.
Question 2
Suppose you notice that the speed approaches 60 km/h as the density reduces to 40 vehicles/km on a certain road. Assuming linearity, calculate the free flow speed and jam density.
💡 Hint: Use the inverse relationships to backtrack your values.
