This paper describes the influence of a forest road on the forest yield, according to a computer model. We have analysed the changes of the map on wood extraction types, and forest taxes in the areas chosen on which the road has a direct impact. The calculation compares construction and maintenance costs with a difference in forest taxes as a consequence of altered wood extraction costs. The discounted value of costs and yield is compared according to three criteria depending on assumptions on establishing the forests openness. Our research work has shown that the further increasing of a road network in open forest areas does not return construction and maintenance costs for roads, considering only the lower costs of wood extraction. Therefore, alongside the economic function, the road must have a series of social functions that cannot be established in financial terms as they have not been established as yet. The comparative procedure is entirely deterministic, repeatable and adapted to the use of a computer model that establishes the influence of existing or newly planned wood roads.
