"Unjamming Traffic with Computers" by Kenneth R. Howard. ScientificAmerican, October 1997, pages 86-88.

This article describes current methods of mathematically modeling trafficpatterns. Some of these methods are based on a mathematical construct known ascellular automata. More sophisticated systems are under development whichinclude simulation of such driver behavior as cutting off other drivers.
