The primary sources of anthropogenic and technogenic impacts on the environment of urban and suburban areas of the Voronezh and Saratov Regions which are part of the Khopyor River Region have been identified. Among the combined urbanized and man-made sources it is necessary to distinguish the activity of pedestrians and road transport. These conditions characterize the local background of the total anthropo-technological load in relation to the settlements of the research area. Its main manifestations include soil compaction, density of the road and path network and clutter. Arithmetic mean values of degradation impacts were analyzed for settlements in the subregion under consideration. A scale of point-based environmental assessment of the state of the environment is developed for differentiated localities in the Khopyor River Region. High anthropogenic and technogenic load is found in Balashov, middle - in Borisoglebsk, Rtishchevo, low - in Povorino and Gribanovsky, an extremely low load - in Romanovka, Arkadak and Novokhopersk. The obtained and analyzed values of anthropogenic and technogenic loads on the environment demonstrate the features of its state and the direction of its degradation, the levels of environmental comfort of urbanized areas for the population. The system of environmental quality management, urban and suburban environmental management in the Khopyor River Region should be reoriented to an ecosystem basis using the environmental assessment criteria and the environmental monitoring results presented and analyzed in this paper.

Branch Xa of Pan-European Transport Corridor X has a strategic importance for Croatia since this corridor (Corridor branch) enables linking of Croatia with Slovenia and Austria, which, according to the current data on the structure of trade in goods from countries, is counted among five most important Croatian trading partners. Therefore, the valorization of the branch of Corridor X has unquestionable importance for the Croatian economy and the associated surroundings that gravitate in the transport route. Conditional on the numerous geo-transport and socioeconomic factors, the valorization of transport corridor on the transport market is determined also by the value of transport (traffic) services that are determined by the costs incurred in its production. Accordingly, the underlying problem of the present study is to analyze the external costs of the branch of Corridor X which, although, belong to the category of social costs borne by society, have the intention to become, over various regulatory measures (excise), an integral part of the costs of the conveyor. With the aim of the research in this study, which, generally, supports the need for internalization of the external costs, as the essential factors of valorization of the transport corridors, a comparative analysis of external costs of the branch of Corridor X between the road and rail transport was performed. As input data, the results of in-depth analysis were used, resulting from the studies of the European Commission for the European Union, specifically Studies for Corridor X and Studies on East-Mediterranean transport routes. The research results show that the mean values of external costs of freight rail transport on the branch Xa are almost five times fewer than the average value of external costs of road transport and that, in accordance with the purpose of these investigations, the internalization of external costs is unquestionably required for planning the traffic flows and valorization of the route.

On The Road

The dimensions and weight of machines, structures, and components that need to be transported safely by road are growing constantly. One of the safest and most widely used transport systems on the road today due to their versatility and configuration are modular trailers. These trailers have hydraulic pendulum axles that are that are attached in pairs to the rigid platform above. In turn, these modular trailers are subject to limitations on the load that each axle carries, the tipping angle, and the oil pressure of the suspension system in order to guarantee safe transport by road. Optimizing the configuration of these modular trailers accurately and safely is a complex task. Factors to be considered include the load’s characteristics, the trailer’s mechanical properties, and road route conditions including the road’s slope and camber, precipitation and direction, and force of the wind. This paper presents a theoretical model that can be used for the optimal configuration of hydraulic cylinder suspension of special transport by road using modular trailers. It considers the previously mentioned factors and guarantees the safe stability of road transport. The proposed model was validated experimentally by placing a nacelle wind turbine at different points within a modular trailer. The weight of the wind turbine was 42,500 kg and its dimensions were 5133 × 2650 × 2975 mm. Once the proposed model was validated, an optimization algorithm was employed to find the optimal center of gravity for load, number of trailers, number of axles, oil pressures, and hydraulic configuration. The optimization algorithm was based on the iterative and automatic testing of the proposed model for different positions on the trailer and different hydraulic configurations. The optimization algorithm was tested with a cylindrical tank that weighed 108,500 kg and had dimensions of 19,500 × 3200 × 2500 mm. The results showed that the proposed model and optimization algorithm could safely optimize the configuration of the hydraulic suspension of modular trailers in special road transport, increase the accuracy and reliability of the calculation of the load configuration, save time, simplify the calculation process, and be easily implemented.

About 36% of fatal road accidents in Norway involve at least one driver who is “at work”. It has been argued that the implementation of rules clearly defining the responsibility of road transport companies to prevent work related accidents, by implementing safety management systems (SMS), could lead to increased safety. In the present study we tested the validity of this suggestion, by examining the influence of different sector rules on work-related accident prevention in Norwegian road and maritime transport. In contrast to the road sector, the maritime sector has had rules requiring SMS for over 20 years, clearly defining the shipping companies responsibility for prevention of work-related accidents. The aims of the study were to: (1) examine how the different sector rules influence perceptions of whether the responsibility to prevent work-related accidents is clearly defined in each sector; and (2) compare respondents’ perceptions of the quality of their sectors’ efforts to prevent work-related accidents, and factors influencing this. The study was based on a small-scale survey (N = 112) and qualitative interviews with sector experts (N = 17) from companies, authorities, and NGOs in the road and the maritime sectors. Results indicate that respondents in the maritime sector perceive the responsibility to prevent work-related accidents as far more clearly defined, and they rate their sector’s efforts to prevent accidents as higher than respondents in road. Multivariate analyses indicate that this is related to the scope of safety regulations in the sectors studied, controlled for several important framework conditions. Based on the results, we conclude that the implementation of SMS rules focused on transport companies’ responsibility to prevent work-related accidents could improve safety in the road sector. However, due to barriers to SMS implementation in the road sector, we suggest starting with a simplified version of SMS.

The work, based on previously little available for research, as well as materials and documents found in archival institutions, reflects the legal basis for ensuring road safety in 1948-1953, the state and organizational and legal measures taken in the field of combating accidents in road transport at the republican level by the example Ukrainian Soviet Socialist Republic. Attention is focused on the key problems that determine the development of the road safety system, the measures taken, their effectiveness, mistakes and achievements. Measures to counteract accidents in vehicles are investigated from a historical and legal standpoint, a critical and detailed analysis of decrees and orders of the government, departmental regulatory legal acts. It was found that the presence of a significant number of administrative decisions of the republican authorities of Soviet Ukraine, although it was a rather progressive step for its time, did not fully take into account the reality of achieving the set goals, local conditions and peculiarities. At the same time, the functioning of the emerging road safety system was significantly hampered by the lack of a unified national policy in the context of the rapid growth and development of the country’s automobile and road complex.

Allocation Decisions

Shelter location and traffic allocation decisions are critical for an efficient evacuation plan. In this study, we propose a scenario-based two-stage stochastic evacuation planning model that optimally locates shelter sites and that assigns evacuees to nearest shelters and to shortest paths within a tolerance degree to minimize the expected total evacuation time. Our model considers the uncertainty in the evacuation demand and the disruption in the road network and shelter sites. We present a case study for a potential earthquake in Istanbul. We compare the performance of the stochastic programming solutions to solutions based on single scenarios and mean values.

This paper aimed to present a model of natural environment management in national parks in Poland in the context of increased tourist traffic. The research area comprised Polish national parks as they are characterized by barely altered nature, little human impact, and undisturbed natural phenomena. The methods involved the observational method, literature analysis and criticism, and the in-depth interview method employed in November 2019. The respondents included national park management staff. The questions were prepared in accordance with the Berlin Declaration principles of sustainable tourism development and were extended with the authors’ own items. The questionnaire contained 17 questions, grouped in four parts: science and documentation; tourism; cooperation and education; environmental threats. The results indicate that in order for actions to prove efficient in a park, a conservation plan should be carefully developed. Its correctness requires monitoring the state of the environment, tourist traffic size and trends, and tourists’ impact on the environment. An important condition for effective tourism management in parks is to increase the competences of the administering bodies and knowledge regarding individuals’ responsibilities. Boards should be able to evaluate and modify conservation plans, spatial development plans, municipality development strategies, and projects for investments within the parks.
