2 cards from this section. Quick, good the night before a test.
Define Greenshield’s model.
Think about the basic equation it represents.
What does jam density refer to?
Consider the scenario where no vehicles can move.
What is the basic assumption of Greenshield’s model?
Consider how speed behaves as density changes.
True or False: Shock waves can only move backward in traffic streams.
Reflect on the movement of vehicles and how obstructions affect flow.
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.
Make sure you are following the model's guidelines!
Discuss how different traffic behaviors during peak times deviate from simplistic models like Greenshield’s.
Think about human behavior in traffic.
