Stuck in rush hour traffic one night about ten years ago, my friend Andre turned to me and predicted that someday people would zip around above traffic in their own personal pods. I told him it was one of the dumbest things I had ever heard.
But it looks like Andre was on to something. For years transportation types have been debating the viability of what is known as Personal Rapid Transit (PRT), and now several projects are underway that indicate the age of the pod may be upon us.PRTs are systems of independent vehicles that provide private, on-demand, nonstop travel for people or small freight, riding on small, overhead guideways. The cars run above existing roads and are powered entirely by electricity. Advocates of pod transport say it offers the convenience and personal experience of an auto without the gasoline, insurance, pollution, accidents, or congestion.
