Interactive Quizzes

Quick quizzes to reinforce your learning

Question 1

What is the basic assumption of Greenshield’s model?

Speed decreases linearly with density
Speed increases exponentially with density
Flow is constant regardless of density

💡 Hint: Consider how speed behaves as density changes.

Question 2

True or False: Shock waves can only move backward in traffic streams.

True
False

💡 Hint: Reflect on the movement of vehicles and how obstructions affect flow.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a free flow speed of 60 km/h and a jam density of 200 vehicles/km, calculate the maximum flow using Greenshield's model.

💡 Hint: Make sure you are following the model's guidelines!

Challenge 2 Hard

Discuss how different traffic behaviors during peak times deviate from simplistic models like Greenshield’s.

💡 Hint: Think about human behavior in traffic.
