A 3-D MODEL FOR OPTIMAL ALIGNMENT SEARCH SYSTEM OF HIGHWAY DESIGN BY EXTENDED DIGITAL MAPPING DATA

Abstract

Inflection of the three-dimensional information is promoted by CALS/EC. In this study, we try that we let three-dimensional CAD link OHPASS which is a road optimal alignment search program. We handle a Control Point by a road optimal alignment search program by GA with the three-dimensional topography provided through 3-D CAD from extended Digital Mapping data. We took the result in 3-D CAD and tried that we let the 3-D model that we made link VR. By VR, we can expect scene evaluation at the time of the road linear plan and that road structure evaluation, the consensus building and a briefing session can use it effectively.
