In this model the turtles are cars traveling through an intersection. The user has the ability to control the number of carscoming from each direction, the speed of the cars, and the timing of the light at the traffic intersection. Once the number and speed of cars is selected, the user should run the simulation and adjust the timing of the traffic light so as to minimize the amount of waiting time of cars traveling through the intersection.
For detailed instructions on using the program, take a look at the info window from the Traffic Intersection model.
