Of interest to urban planners, environmentalists, transportation planners, engineers, and others from a variety of disciplines, this University of Washington site provides information on unconventional transportation technologies with an eye to replace cars and trucks with environmentally sound mass transit and freight options. Special attention is therefore paid to non-auto technologies. A few of the innovative transportation designs included here are supported vehicles like the Cabintaxi and suspended vehicles like the Sky Train. While some of the descriptions of these unusual vehicles are on-site, there are also many hyperlinks leading users to external sites containing new and fascinating technology.
