Challenge Problems
Push your limits with challenges.
Question 1
Given a data set of densities and speeds, derive the Greenshield coefficients and evaluate how they show the behavior of a congested before and after flow.
💡 Hint: Use statistical tools to identify patterns in the data.
Question 2
Model a hypothetical traffic scenario using Greenshield's equations to predict traffic behavior at peak times. What variations might you expect?
💡 Hint: Think about real-world impacts on the theoretical model you learned.
