33.1. Overview

Try these first

1. 1.

   What are the three key parameters of traffic flow?

   Hint

   Think about what you measure in traffic studies.

2. 2.

   What concept does Greenshield's model focus on?

   Hint

   Remember the first model we discussed.

3. 3.

   Which mathematical model focuses on a linear relationship between traffic speed and density?

   • A) Greenberg’s Model
   • B) Greenshield's Model
   • C) Underwood's Model

   Hint

   Think about the first model we discussed in class.

4. 4.

   True or False: Traffic stream models are only theoretical and have no practical application.

   • True
   • False

   Hint

   Consider how these models impact city planning and operations.

5. 5.

   You are tasked with developing a new traffic flow model based on real-time data. Outline the steps you would take to ensure its effectiveness and applicability in urban settings.

   Hint

   Consider all the parameters we discussed and how they fit into a real-world application.

6. 6.

   Critically examine how traffic parameters change during peak traffic hours and propose adjustments to the existing models to account for these changes.

   Hint

   Think about human behavior during rush hour versus regular hours.
