PUMAS (poo' • mas) -- is a collection of brief examples showing how math and science topics taught in K-12 classes can be used in interesting settings, including every day life.
The examples are written primarily by scientists, engineers, and other content experts having practical experience with the material. They are aimed mainly at classroom teachers, and are available to all interested parties via the PUMAS web site.
Our goal is to capture, for the benefit of pre-college education, the flavor of the vast experience that working scientists have with interesting and practical uses of math and science.

Probability and Traffic Signals by Elliott Ostler
It seems that traffic flow problems are becoming more and more common these days. In fact, despite the most noble efforts of city planners, even when there is very little traffic on the road, waiting seems to be a fact of life. So what is the probability that you will have to wait at a particular traffic signal, or perhaps more appropriately, what is the average amount of time you can plan on waiting? Let’s look at a simple probability analysis related to traffic lights to find out.

We are always looking for neat examples of Practical Uses of Math And Science.
