Economic Fundamentals for Selecting Directions for Modernization of Highway Network

The paper proposes a methodological approach to selection of rational directions for modernization of highway network while taking into account an increasing requirements of the national economy in a modern transport infrastructure being formed under conditions of the development of national transport and logistics system. The initial data required for variant development of design solutions contain information on existing transport and operational characteristics of the road network, intraand inter regional transport and economic relations, formed logistics supply chains, volume and structure of transportation and possible development stages for certain sections of highways. In this case initial data have a certain degree of uncertainty that requires to take design decisions with due consideration of the possibility to change information in a certain interval. The proposed options to use economic criteria make it possible to assess efficiency of logistics systems and their participants carry out operations pertaining to supply and handling of products and cargoes on specific sections of a road network and these measures are proceeding from common goals based not only on national or regional level, but also on the global level in the context of strategic planning. Study objectives play a significant role in selection of a calculation method, as well as its structure, a degree of its aggregation. Construction of an optimal scheme for modernization of a highway network presupposes to determine such totality of design solutions for construction, reconstruction and repair of motor roads with year-wise distribution for calculation period and certain network sections and such distribution of their freight flows when an amount of the reduced costs for transportation of the entire volume of products and modernization of motor roads would be minimal in accordance with transportation rates.
