        TrafficJam - Part 3: Brainstorm

        The students meet Dave Musicant, a computer science professor and explain that they want to try to reduce the amount of time they spend waiting at red lights at the intersection by their school.  They brainstorm what kinds of data they will need to collect at the intersection.  They decide to time the current traffic light cycle and green/yellow/red phases, count the number of cars that approach the intersection from each direction and how many of them continue straight or turn, and count the number of pedestrians crossing in every direction.
