Watch cars make their way through a 4-way intersection, by "claiming" the quarters of the intersection they need to cross to make it to the direction they want to go. If a quarter is already claimed, a car will wait before driving onto the intersection. This way, several cars can cross at once, but they won't lock up or crash. * click the traffic signs to change the directions cars can turn * When a car "claims" a quarter, it is highlighted in the same color. * You can see where the cars want to go by looking at the blinkers/turn signals in the headlights. * adjust the slider to increase/decrease traffic
