The Advanced Transport Group at the University of Bristol, upon considering current traffic congestion problems in England and throughout the world, attempted to "identify the ideal system for future urban transport." The group's work has led to the development of the Urban Light Transport (ULTra) System. This paper, published in September 2002, describes the engineering challenges and accomplishments of the endeavor. Thus far, a test track has been constructed, and an initial vehicle design was successfully demonstrated. The ULTra home page provides much more information, documents, and videos.
