"Throughout the past decade, states, cities and regional transportation agencies have been experimenting with intelligent transportation toys to ease the flow of traffic and improve safety. In the past few years, that experimentation has accelerated. With both road and transit capacity strained and money for new construction scarce, high-tech solutions are becoming the premier way to squeeze more space out of existing highways and make bus and subway systems more rider-friendly."
