The guideway is the most expensive item in a PRT system. Yet in all but a few cases the design of the guideway was more or less an afterthoughtsomething that did not require a great deal of attention. This is a major reason many PRT systems have not survived. Primary attention had to be placed on the development and design of the control system because it was the single technological advance that made consideration of PRT possible. With limited resources, control downgraded the importance of everything else about a PRT system. During the long history of PRT development and design, guideways have been designed for Veyar, Monocab, TTI, StaRRcar, Uniflo, Dashaveyor, Morgantown, The Aerospace Corporation PRT System, Cabintaxi, CVS, Aramis, ELAN-SIG, VEC, Swede Track, Mitchell, SkyCab, Taxi 2000, PRT 2000, Microrail, Skytran, MonicPRT, ULTra, Vectus, and others. This plethora of designs likely has had much to do with the reluctance of city planners to recommend PRT. No two of these guideway designs are very close to each other. Now that the control problem is well understood, it is time to turn more attention to the guideway. The purpose of this paper is to stress the importance of adequate consideration of guideway design requirements and criteria as the basis for the design of guideways that have the potential of becoming standardized and widely deployed.At the University of Minnesota early in my work on PRT I coordinated a Task Force on New Concepts in Urban Transportation. We conducted planning studies of PRT for Minneapolis, St. Paul, and Duluth and soon saw that such studies were mandatory to real understanding of the problems of designing and installing a PRT system, including its guideway. We discussed our work with many public officials, planners, and interested citizens not only in Minnesota, but in many locations around the United States, Canada, Europe, and Asia. We reviewed the work of the many government-funded studies related to AGT design. The most helpful for guideway de-

TAXI 2000 is the result of a comprehensive process of "top-down'' design optimization beginning "from scratch" and subject to a variety of practical constraints. It builds on over two decades of work on automated transit in virtually every industrialized country and on a comprehensive theory of transit economics and technology developed by the author. The system's low cost is a result of discovery of optimum configurations and of technology advances not available a decade ago. The paper includes a description of the system and the process of and basis for its development; discussions of technical areas of dependability, safety, evacuation and rescue, power requirements, and performance; discussions of the state of development, development plans, process of certification, and problems in implementation of the PRT concept. General DescriptionTAXI 2000 is a new urban transportation system designed from the beginning based on thorough interdisciplinary analysis of transit needs and requirements in specific urban areas. It evolved from a process of "top-down'' design aimed at finding a combination of technologies that would solve real problems of urban areas, considering the moderate density patterns in which people do, in fact, live. This is in contrast to the commonly practiced approach of rail transit planners, which is to promote very high-density living patterns already known to be socially undesirable, but which make these conventional rail systems approach economic viability. To achieve our aim of providing service where people are has required that we strive rigorously to both minimize cost and maximize service. The remarkable feature of the true personal J.
