Due to the need for mass construction of transport routes there is a need to develop theoretical foundations and methods of their design, which will simplify the design process, develop geometric models to optimize transport links, improve existing and create new methods of geometric modeling of optimal trajectories. terrain and road parameters. In the process of designing transport links, the main objective function is the economic effect of their construction. The cost-effectiveness of the overpass should include minimizing the length of the road, taking into account construction costs, which also depend on the minimum allowable parameters of transport routes, the peculiarities of traffic. To develop an optimization model for determining the trajectory of the road in the territorial design, the analysis of geometric parameters of the features of transport routes such as the minimum: turning radius in terms of Rgor; profile angle of rise of the path angle α; profile angle of descent path angle β, profile radius of path convex curves Rprof1; profile radius of the path concave curves Rprof2; step of supporting structures of engineering supports ∆L. And also the maximum height of transport engineering support ∆H. These indicators will serve as limitations in optimizing the trajectory of overpasses. А conditional classification of relief surfaces taking into account geometrical features and parameters of different types of overpasses is offered. Its use will promote increase of quality of designing of transport ways on a terrain relief, simplification of design process and improvement of quality of design planning decisions at territorial designing. The further use of the optimization model to determine the trajectory of roads for different types of transport will improve the quality of design, solving planning problems of spatial design.
