This paper discusses and presents graphical representation of roads as 3D geometric object in virtual reality and Matlab in accordance with civil road construction rules concerning aspects for macro level: vertical and horizontal road alignment and micro level: surface rugosity. In the following are presented implementation methods and the advantages for road graphical modeling in 3D with the help of virtual reality in both macro and micro level. The goal of the paper is to present a modular approach for development of a fully integrated 3D road model using virtual reality with Matlab. The computed parameters are included into VRML/X3D files which are useful for development of car driving simulators.
