Outline of Final Research Achievements

In recent years, while the informatization of construction production has progressed, mainly through BIM/CIM, research on the management of knowledge and wisdom required at the design stage is still in its infancy. In this study, the pyramid model of information defined in previous studies is applied to road design, and an information model that can store information on the considerations and innovations in the design process and the thinking of designers and operators in decision-making is constructed. A flow analysis of the existing road design process was carried out to clarify the existence of an information chain structure and to show that the process can be defined as a recursive structure based on sectioning and that each design stage can be expressed as a function with topography, geology and environment as inputs and geometric structure as outputs. The results show that the design phase can be expressed as a function of input geomorphology and output geometry.
