The development of road network infrastructure is an important component of the economic development of the European Union. Updating of the road network contributes to the integration of the economies of countries into a coherent whole. The road network provides the free movement of citizens, the movement of goods and the effective implementation of various services. The increase in the length of the road network leads to an increase in the financial and material costs necessary to ensure its maintenance and repair. One of the ways to reduce costs is by strengthening the physic-mechanical and operational characteristics of the pavement due to the widespread use of cement concrete. The quality of the pavement of cement concrete depends largely on the rational selection of its composition. This allows a significant increase in the durability of road pavement. The purpose of the research was: the development of recommendations for the rational selection of the composition of the road pavement material of cement concrete, aimed at upgrading longevity, and taking into account its frost resistance grade. According to the goal, the following tasks were developed: the analyses of the climatic zones in which the road network of the European Union is located; the development of a research plan, a selection of the response function and influence factors; the study of physico-mechanical and operational characteristics of the researched material of road pavement; on the basis of the obtained data, the calculation of the complex of experimental-statistical models, which describe the physico-mechanical and operational characteristics of the road pavement material; on the basis of experimental statistical models, a method was proposed for selecting the rational compositions of the cement concrete pavement road material depending on the conditions of its application. The results presented in the article can be used in engineering and scientific practice for the selection of road pavement from cement concrete for highways.

This article contributes to the research on the expansion of the Swedish post-war road network by illuminating the role of tourism in addition to political and industrial agendas. Specifically, it examines the “conceptual construction” of the Blue Highway, which currently stretches from the Atlantic Coast of Norway, traverses through Sweden and Finland, and enters into Russia. The focus is on Swedish governmental reports and national press between the 1950s and the 1970s. The article identifies three overlapping meanings attached to the Blue Highway: a political agenda of improving the relationships between the Nordic countries, industrial interests, and tourism. Political ambitions of Nordic community building were clearly pronounced at the onset of the project. Industrial actors depended on the road for the building of power plants and dams. The road became gradually more connected with the view of tourism as the motor of regional development.

The choice of the most beneficial road alignment variant is a multicriteria issue, based on transport, economic, social and environmental criteria. The criteria chosen for a multicriteria analysis can be expressed through measurable or immeasurable parameters. In order to compare and assess the variants it is necessary to normalize the criteria, which means a rescaling of their value, so that the criteria values fall into a specific range. The main aim of normalization is to assign an identical weight to each criterion in relation to other criteria. This article presents a review of the influence of criteria normalization methods and the variant assessment methods on the choice of the most beneficial road alignment variant on the example of the bypass of the town of Księżyno, which is a stretch of Regional Road 678 near Bialystok. Four variants of road alignment were compared and their ranking was created using six assessment methods. It was proven that the choices of the criteria normalization method as well as the variant assessment method both have signifi­cant influence on the result of the multicriteria analysis in the decision-making process of selecting the road alignment.

Summary Asclepias syriaca is an invasive alien plant that has recently spread in Central Europe. The spatiotemporal spread of A. syriaca was reconstructed based on the distribution data for Austria. A. syriaca has increased in abundance and range, especially after the year 2005. At present, the species occurs primarily in eastern Austria (Vienna, Lower Austria), while it was rarely recorded in southern and western Austria. Further spread and range filling is probable. Moreover, the distribution of A. syriaca along roadsides and the role of road type and adjoining land use in facilitating its spread were studied in an area of high presence of the species in Lower Austria in 2018. It was shown that A. syriaca occurred regularly along roadsides and the chance of finding A. syriaca was higher along unpaved roads and along roadsides bordered by forests and grassland. The results indicate that the road network contributes to the spread of A. syriaca in the study area, most likely by providing suitable and well connected habitats. If A. syriaca densities are to be lowered, emphasis should be placed on both a proper roadside management (e.g., mowing regimes) and on the control of the species in the respective adjacent habitat.

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.

Abstract The selection of a road route plan is an essential preliminary task. The choice of the route greatly influences its function, role in the road network, economic development of the areas along the route, and the return on investment. In this paper, qualitative analysis and evaluation of the details of the proposed route options in terms of ecological environment and engineering economy are carried out through fuzzy hierarchical analysis, based on the route data from Bushang to Bizhou, to combine the principles of the routes and develop several route options. Among the pre-determined route options, screening and comparison are carried out, and Option II is proposed as the recommended route.

This paper presents the results of analyses that concern the benefits from the planned construction of a dam across the Vistula in Siarzewo. The simulated transport model developed in the VISUM environment has been used to determine the forecast traffic intensity, the value of traffic volume indices, transport activity, travel times of drivers and passengers as well as the costs of environmental impact. The above-mentioned characteristics have enabled to determine savings both in terms of traffic costs and environmental impacts resulting from the dam construction. The paper indicates that the implementation of the investment project improves traffic conditions on the road network and reduces the transport environmental impact in Kujawsko-Pomorskie Province. Moreover, it has been found that the revealed effects concern in particular the first years after the launch of the project. The development of the road network diminishes the role of the analysed investment project significantly.
