Selection and management factor analysis of urban infrastructure for U-City construction

U-City (Ubiquitous City) projects are being actively pursued, where ubiquitous technology is applied to large-scale new city development. U-City is all about creating a ubiquitous environment which, on the basis of Information Technology (IT) infrastructure, is combined with construction technology to make our lives easier and more comfortable. More recently, the concept of a U-Eco City (Ubiquitous Eco-friendly City) is widely discussed to incorporate the notion of a ‘green city’ into the U-City concept, with relevant research efforts also underway. In accordance with this tendency, this paper sets the criteria for selecting the key infrastructure required to build an effective U-City and conducts expert surveys and a Delphi analysis. For roadway facilities on which the highest priority is known to be placed, this paper analyzes their required VE-based functions and extracts management factors. The AHP technique is employed to analyze the relative importance of the nine core management factors which are required to build the U-City in roadway facilities. Among these key factors, ‘Establishment of a Ubiquitous System’ is shown to be of the greatest importance, followed by ‘Analysis of an Automation System’, ‘Establishment of Factor Technology’ and ‘Ideation of an Eco-Friendly City’. Formulating U-City establishment plans on the basis of high-priority management factors will enable the effective construction of roadway facilities. Hence, this paper sets work standards for individual management factors and proposes development guidelines.
