Oh boy, here’s something that I suspect is going to become a major time sucker for me, Gridlock Buster–an online game developed by the Intelligent Transportation Systems Institute at the University of Minnesota.

Click on an intersection to change the traffic light, and let the cars go. The more you can get through without people becoming antsy, the more points you accumulate.

The aim of the challenge, according to the folks at the University of Minnesota, is to educate young people about the role of traffic management, and its impact on economic activity and environmental performance.

The game gradually increases in difficulty as you move up the levels. You contend with one and two intersections at first, and then more intersections, and more vehicles, so get ready to time traffic lights!
