Technology that cannot be excluded from 4th industry is self-driving sector. The self-driving sector can be seen as a key set of technologies in the fourth industry, especially in the DB sector is getting more and more popular as a business. The DB, which was previously produced and managed in two dimensions, is now evolving into three dimensions. Among the data obtained by Mobile Mapping System () to produce the HD MAP necessary for self-driving, Point Cloud, which is LiDAR data, is used as a DB because it contains accurate location information. However, at present, it is not widely used as a base data for 3D modeling in addition to HD MAP production. In this study, MMS Point Cloud was used to extract facilities around the road and to overlay the location to expand the usability of Point Cloud. Building utility poles and communication poles DB from Point Cloud and comparing road name address base and location, it is believed that the accuracy of the location of the facility DB extracted from Point Cloud is also higher than the basic road name address of the road, It is necessary to study the expansion of the facility field sufficiently.

Extension IFC schema of subsidiary facilities were developed for the purpose of establishing an information model standard for roads. The IFC entities, types and properties for subsidiary facilities were defined through an analysis of the road design documents for the extraction physical component and design information. The converter and viewer for applying the new schema were then developed. Subsidiary facilities BIM models were converted to new IFC models to verify the research results. Standard BIM-based delivery and verification systems are enabled by using a standard model converted by new schema. Furthermore, it can establish an open BIM environment using an IFC over the entire life cycle of the civil engineering project.

This paper provides information for quantitative evaluation of transportation technology, technology development, and transportation R&D and construction engineering policy agenda. Technology classification structure and key words were established and survey was performed to identify key words of technology for transportation. Then, competitiveness of patents and journal articles is evaluated for Korea, USA, Japan, Germany, France, and England. As a result, USA is the most competitive country for all technology categories based on patents and journal articles. Korea is grouped in upper-middle class for overall transportation technology level. However, there are some variances among the level of technologies. The results of this research can be utilized to establish a road map for transportation R&D and plans.

도로명주소는 2014년부터 본격 사용 중에 있으며 점차 활용이 증가하고 있다. 도로명은 행정구역과 함께 사용되며 거점을 표현하는 기준점으로서 도로명의 간결성은 우편/물류 등의 다양한 분야에서 주소정보를 입력하는 업무에서 중요한 요소이다. 본 논문에서는 도로명주소 체계에서 정의된 도로명 부여 규칙을 토대로 실제 사용 중인 도로명에 대해 살펴보고 도로명 주소 입력 간편화 등의 관점에서의 개선 방향을 제시한다.

컴퓨터의 발전에 따라 현재 제4세대 수치사진측량의 활용도가 광범위하게 진행되고 있다. 특히 비디오동영상을 이용하여 실용적이며, 비전문가들도 활용할 수 있는 부분들이 증가하고 있다. 이러한 현시점에서 국가산업의 중추적인 시설물 도로분야에서 도로안전진단과 유지관리목적으로 도로정보획득 및 도로정보수집에 많은 연구를 하고 있다. 따라서, 본 연구에서는 실용성, 경제성이 있는 비전문가용인 디지털비디오 동영상을 이용하여 도로중심선의 3차원 위치정보를 추출하여 도로정보화사업의 기본적인 자료로 제공되리라 판단된다.

Since IFC (Industry Foundation Classes) 4 is based on the representation of 3D elements for an architecture project, and does not define standardized shapes for civil projects such as roads, bridges, and tunnels etc, it has limitations in securing interoperability for exchanging a shape information model for the civil projects. Besides, since road facilities have a linear reference, which is modeled along the center alignment, it is difficult the designers to create a standardized 3D road model. The aim of this study is to configure structure elements and their attribute for a road in the perspective of 3D design for developing a shape information model for the road. To solve these issues, this study analyzes the design documents, which consist of a road design handbook, guide, specifications and standards, and then extract shape elements and their attributes of road structures. Such shape elements are defined as an entity item and we review a hierarchical structure of a road shape defined by a virtual road model. The detailed elements and their attributes can be utilized as a 3D shape information model for constructing BIM (Building Information Modeling) environment for Infrastructures. Besides, it is expected that the suggested items will be utilized as a base data for extending to IFC for a road subdividing the detailed shapes, types and attributes for road projects.
