A Concept for Ubiquitous Transportation Systems and Related Development Methodology

Abstract

The purpose of this study is primarily to clarify the concept for ubiquitous transportation systems (UTS) based on ubiquitous computing. Additionally, the key conceptual terminologies related to the ubiquitous computing are reinterpreted for the transportation domain. The 8 key properties are proposed as the necessary and sufficient conditions for the ubiquitous transportation system, which can be represented by "4A" & "4T" "4A" stands for Anytime, anywhere, anything, and anybody, and "4T" stands for Transparency, Together, Transcendence, and Trustworthy. And the architecture-based methodology for UTS is also proposed through comparative analysis of systems development methodologies. Finally, the differences between the existing ITS and UTS are explained.
