The highway is greatly changed by the constant economic growth for a long times the traffic situation such as the large volumes and the performance vehicles, the performance enlargement of vehicles, the high speedization, etc., due to growth economic. A study of an optimal route selection model is researched over late 1980s by development of computer and GSIS, and consisted including research about the optimal route that uses digital terrain model in domestic such as the earth volume calculations, the mass curve output and the automation system construction. Lately, the study of the driving simulation of the highway and the virtual reality using VGIS(Virtual Geographic Information System) is researched. This study shows when the alternative highway selection considered surrounding facilities, development plan and according to estimate amount of traffic and the additional possibility of view analysis and environment effect analysis element will study through 3D simulation method.
