Principles of spatial design for haulage roads

The purpose of the study is to review and analyze the experience of specialists in the field of spatial design of haulage roads for further improving the methodological foundations by providing clarity and visually acceptable degree of spatial curves. Drivers perception of the haulage road as well as overspeeding lead to critical situations or road accidents. A decrease in speed at seemingly abrupt bends on the road affects the efficiency of the log trucking transport. Therefore, the perspective view of the road should clearly orient the driver, that is, be visually clear, clearly changing, ensuring the constancy or modulated reduction of the traffic condition. The need for an optimal spatial solution of the road increases. It is required to determine the conditions under which the visual smoothness and clarity of the most common simple spatial curves when looking from points corresponding to the normal position of the eyes of car drivers is ensured.
