Traffic flow modeling - This could be systems dynamics or agent-based (see http://en.wikipedia.org/wiki/Traffic_flow) and part of the Measuring the World unit. The simulation would involve modeling a section of traffic to see results of uses of traffic control devices. The validation/verification part of this could be to observe an actual section of traffic here in Richmond.

Comments
Pros
- A lot of people have already researched this, and it's easy to validate by standing out and watching traffic in an intersection
- Some statistics and probability
Cons
- Not much science behind this
- We can't change the model and see how it affects real life
Comments
- Could be a good one to teach the verification and validation process
- Charlie did a class like this years ago where they did stand there and count cars and then wrote a simulation
- Make people walk through different halls: have one hallway up and one down, versus both both directions
- Should take less time even if it does walk longer
- Maybe we don't need to do a lot of physical stuff with this one since people are already familiar with traffic
- Idea: bunch of cars that have to get somewhere, and you have a limited amount of concrete and traffic control and you have to get cars from point a to point b, and you can control how long and control the lights
To Do
- Probably going outside is not practical, but we could look at the speed of cars on the webcam, and we know the % of cars that stop at the pedestrian walk, we could play with this
- See if there's some sort of existing traffic-organizing model
- Tie in to Monte Carlo simulations?
