UTILIZATION OF THREE-DIMENSIONAL INFORMATION IN ROAD CONSTRUCTION PROJECTS

Abstract

 In this research targeting road construction projects, schemes were investigated for utilizing three-dimensional (3D) data distributed in accordance with ISO (Internatio nal Organization for Standardization) and produced by 3D computer-aided design (CAD) software based on the concept of product data models. First, existing literature was classified by work stage as the context for utilizing 3D data. Next, the establishment of standards for exchanging 3D data, revising relevant systems, constructing road data models, realizing work process models, developing 3D CAD engines, and providing 3D data utilization environments are discussed, both as measures that should be undertaken and as future research topics for promoting the utilization of 3D data. Finally, the potential for utilizing 3D data in road construction projects by local government is examined, and the items to be implemented for this purpose are summarized.
