Abstract

S.A.T., Autonomous Transport System [1] is the first 3D Public-Private Transportation System and its design has emerged, not from the traditional transportation schemes, but from urban planning studies derived from a cutting edge Urban Theory. The formulation of the \“Tetra-re-dimension Urban Theory” [1] as a Manifesto, defines the necessity of a paradigmatic shift in terms of the present obsolete conception of cities, based on traditional models of urbanism. The genesis of S.A.T. makes it \“the tool” that would outline the transformation process towards a new Urban Paradigm in the frame of newmillennium mega-cities S.A.T. works based on a 3D-displacement (vertical, horizontal and in gradient). All present means of transportation work on a 2Dbasis; therefore S.A.T. endorses a radical change regarding the conception and regeneration of urban sceneries, breaking-up with the static-use of contemporary cities into what we have defined as 'interactive-verticalism', a 4D-City [1]. S.A.T. addresses a new transportation category and would act systemically as a modifier to all existing means of transportation and as a catalyst as well, to their further development. The research presented in this paper makes focus on Cost Analysis, and aims to develop a framework of ex ante evaluation for the S.A.T. Project from a cost perspective, which could be used by decision makers as well as system designers and promoters. This framework consists of six cost categories, two of which are direct costs; the other four are indirect costs. For each category, certain indicators are defined and cost models are formulated. A real case study has been carried out in the Netherlands, showing a comparison between the S.A.T. system and a Metro system. Finally, conclusions and recommendations for future research are given. Keywords: cost-analysis, future transport system, policy makers.
