Abstract

A highway geometric information system has been developed in this study by utilizing the advantages of the laser scanning technique. The system can accurately interpret the geometric information of highway and can be applied to actual works. To accurately interpret the geometric information of highway, horizontal data on highway were collected promptly and accurately, and then transmitted on a real-time basis using the socket network method. Continuously scanned data were then registered and geo-referenced and the developed technique was verified to have a higher accuracy than other techniques through an accuracy analysis. An algorithm that can automatically separate a horizontal alignment into a straight line, a transition curve, and a circular curve to develop the highway geometric information system. It can increase its efficiency compared to the conventional methods. In addition, an algorithm that can automatically extract design elements of horizontal alignments of highway and applied to an object highway. If we used the construction system that was built, it is judged that it can contribute to use of the development of extraction road element technology.
