Chapter 2: Modeling What We’ve Observed: Queuing Systems
65
The purpose of this activity is to provide a framework for you to think about traffic flow at signalized
intersections. In this activity, you will build a base of knowledge of modeling traffic flow at a signalized
intersection using queuing theory as your model framework. You will learn to recognize patterns through
visualizing arrivals and departures at a signalized intersection. You will also make connections between
words and charts, finding alignment between alternative ways of representing traffic flow patterns.
•
Connect your observation of traffic flow at a signalized intersection with a model framework
•
Represent and interpret queuing diagrams for a range of traffic flow and control conditions
•
