iTraffic Light Deluxe is a 2D arcade simulation game for Mac. The idea is very simple, prevent crashes and congestion; just like a real life engineer. You control when the lights let the traffic flow, so that not too many cars accumulate at the intersection. If it gets too crowded you loose. Also, you need to plan strategically when to let it flow in order to prevent accidents with other cars.
