This paper describes a mechanism for creating 3D highway shapes and producing drawings with the data input and creation function in OHPASS. The functions developed include a method for creating 3D terrain and control points that are input using Civil 3D, and a function for incorporating the calculated results back into Civil 3D.

In addition the system is linked with UC-win/Road Ver.9.0 (produced by FORUM8 Co. Ltd.) 3D VR (Virtual reality) system designed especially for creating a variety of 3D models and running many types of realistic simulations within the 3D VR environment built by the software itself. UC-win/Road is capable of providing various real-time presentations with CG after generating a three-dimensional VR space, and is being utilized extensively in landscape examination, design consultation, and for presentations at project briefings.

The authors have developed a function that loads the results of the road alignment examination obtained in OHPASS, and displays them as horizontal and vertical drawings within the UC-win/Road 3D VR environment. As a feature of OHPASS, it is possible to examine two or more alignments by changing design conditions. Now a function for selecting and loading each and every alignment has been added so that the multiple results of the road alignment examination can be loaded.

In the study, described in this paper, the authors have attempted to link OHPASS, an optimal road alignment search program, with three-dimensional CAD. In addition, by enabling the optimal design calculation results to be loaded into 3D CAD, graphical representations of the design the results can be linked with a 3D VR system. As the design results can be linked with a 3D VR system, they can used to create an integrated 3D VR system. The 3D VR system enables the realistic surrounding landscape of the designed project to be viewed. Within the 3D VR system, dynamic 3D space can be controlled in real time, for example, it is possible to 'drive' on the designed road in virtual space as if we are actually driving .These driving experiences and the visualization in the 3D VR system allows us to examine and evaluate the designed project effectively.
