In road design, it is most important to obtain an optimum road surface (left and right traffic ways, left and right road sides, left and right slopes, etc.) using a number of criteria (sometimes hundreds of criteria), which include a slope, absolute elevation, elevation relative to the groundwater level, distance from the top of pipe-culvert, and others. In most computer-aided design systems, a digital model of the project is built by using a Delone triangulation. This paper deals with a new mathematical apparatus for spatial setting out of box-section roads in the form of a nonclosed polyhedron. The proposed approach to optimizing the road design utilizes the building information modeling for box-section roads in the form of a moving unclosed smooth curvilinear polyhedron.
