The methodology is described and the the optimal density of forest roads has been found for the natural and industrial conditions of the North-Western Federal District. The authors propose decision-making models for choosing the forest roadbed and road topping designs. They also propose a model for evaluating alternative sections of forest roads, a model for selecting key points of the forest resource base and a final optimization model for making decisions on logging roads network design. The developed computer system allows the user to display information in a user-friendly and layer-by-layer form on the required road construction volumes and to obtain a wide list of indicators characterizing both individual sections and all roads as a whole. This system application demonstrated a reasonably good compliance with actual conditions and the ability to adapt to the user's tasks. The proposed solutions make it possible to achieve a significant economic effect for a planning horizon of 5—10 years or more.
