Learn how to manage traffic

I have never been that interested in what is called "intelligent transportation systems" (ITS), which is focused on better managing the road network. But the reality is that you see how if road closures and accident scenes (and the road network impacted by a particular accident) are better managed, then traffic tie ups, especially during rush hour would be reduced.

The other crazy thing is that message boards on highways actually produce traffic tieups and slowdowns, as people slow down to read the message.

Anyway, the Center for Transportation Studies at the University of Minnesota has created an online simulation, Gridlock Buster, a traffic control game based on tools and ideas that traffic control engineers use in their everyday work.

I haven't played it yet, but I intend to as it is something that I need to know more about (without necessarily taking a class in traffic engineering, which I probably will have to do sooner rather than later).
