Abstract
Abstract: Recently, together with the self-driving car commercialization technology development, the precision road map is being made to support the policy. To make the precision road map, exact and precise spatial information around the road, which can enhance the reliability, are needed to be established. Therefore, in this study, the 3D high-precision road spatial information were built using MMS, which facilitates building of the high precision spatial information around the road. Through the information built, the positional information of various facilities required for precision road map were extracted. In the results of verifying the precision based on the information extracted, high precision within approximately 8cm was secured. In the results of this study, MMS-based road spatial information are deeded to be applied effectively not only to the precision road map but also in building and renewal of database for traffic safety installations, national highway management information, etc.
