Modeling

SURFACE 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 mov-ing unclosed smooth curvilinear
