The Impact

The article discusses the importance of investments in railway infrastructure for improving the transport accessibility of the Rzeszów agglomeration. For an intensively developing and expanding Rzeszów agglomeration, accessibility plays a key role not only in determining the value of residential and commercial real estate but, above all, in meeting the needs related to the mobility of the region’s inhabitants from one place to another (e.g. to work or school). Therefore, transport accessibility is an important element of spatial organization and has a significant impact on the level and pace of the socio-economic development in the region. The paper consists of a theoretical part and a case study characterising several investment projects in the railway transport infrastructure. The aim of the article is to present the impact planned and implemented investments in rail transport to improvement of accessibility, and thus the level and quality of life of the inhabitants of the Rzeszów agglomeration. The considerations were supplemented with an attempt to assess the current transport accessibility in the region and the changes that will occur as a result of the implemented investments.

The Impact

The article considers the problem of seasonal uneven transportation and its impact on transport infrastructure loading. The objective of the study is to develop scientifically sound recommendations for monitoring seasonal unevenness of transportation and infrastructure loading based on its adequate assessment; conducting economic assessment of the impact of seasonality of transportation on the indicators of current and investment activity of railway transport; making recommendations to further reduce unevenness of transportation, or at least prevent its growth. The authors solved the following tasks: a reasoned, logically structured sequence of economic assessment of the impact of seasonality of transportation on the indicators of current and investment activities of railway transport was formed, and scientifically based recommendations were proposed to further reduce uneven transportation (toprevent its growth). The following methods were used: logical and analytical tools, methods of statistical analysis, economic-mathematical modelling and technical and economic calculations. As a result of the study, the authors revealed that seasonal uneven loading of railway infrastructure leads to a decrease in quality of transportation and a deterioration in the market image of the railway industry, an increase in operating costs and cost of transportation, that is, to a decrease in efficiency and competitiveness of railways. The uneven transportation negatively affects the effectiveness of investments in development of railway transport. The analysis made it possible to formulate a theoretical model of influence of seasonal unevenness of railway infrastructure loading on efficiency of its use and development. It is advisable to use the methodological toolkit for assessing seasonal unevenness of railway infrastructure loading for its in-depth retrospective analysis, identifying the main factors affecting unevenness indicators and determining the maximum permissible level of seasonal unevenness. The developed model of influence of seasonal unevenness of loading on use and development of railway infrastructure allows to carry out economic assessment of seasonal unevenness, is a tool to improve planning and management of transportation activities and development of railways. The reduction in seasonal unevenness of transportation should be considered as a factor increasing the economic efficiency of not only the current, but also investment activity of the railway transport, while its growth should be considered as a specific type of risk for effectiveness of implementation of railway infrastructure development projects.

Qualitative Characteristics

The development of infrastructure, and transport infrastructure in particular, can be attributed to key factors in the economic growth of regions. In conditions of the development of society, the requirements for infrastructure are constantly increasing, which inevitably changes its quantitative and qualitative characteristics, modifying the structures of the infrastructure complex of a specific region. At the same time, it is necessary to take into account both the impact of the social and economic situation in a particular region on the development of infrastructure, and the reverse impact of infrastructure on regional development. In this connection, the transport infrastructure in the article is proposed to be considered as a subsystem of the regional economic system, which establishes institutional links and provides transport services both to the sectors of the regional economy and to the population. The increase in government spending on infrastructure development provides a multiplier effect in the economy. However, in modern conditions, a country may face investment restrictions. Most likely, in the coming years, the share of government spending on infrastructure will decline due to falling incomes first of all when selling energy resources. Obviously, in such conditions it is necessary to change the traditional formsand methods of managing the infrastructure complex, to find new "growth poles". The urgency of improving the spatial organization of the economy is explained by the need to increase the quality of life of the population on the basis of increasing the efficiency of the functioning of the regional economy. The use of transport accessibility as a criterion for the development of regions destroys departmental barriers,promotes a combination of sectoral and territorial planning, allows to take into account both the efficiency of the commercial activity of the transport complex itself, its quantitative and qualitative characteristics, and the impact of transport on economic and demographic processes, the standard of living of the population, and territorial economic development.At the same time, one of the problematic aspects of ensuring transport accessibility is its assessment. Since, if there are difficulties with the adequacy of the results of the assessment of existing realities, then decisions to increase it, as well as decisions related to the development of regions, may prove to be erroneous.The article analyzes different approaches to assessing the impact of transport on the social and economic development of regions. Methods for determining the impact of the territorial concentration of the transport infrastructure, taking into account production, social and population factors, are proposed.

Required Quality

Current geopolitical and economic conditions for the functioning of railway transport in most post-Soviet states are such that it is extremely difficult to provide required quality of transport services and break-even operations at high expenses for maintaining the railway infrastructure and rolling stock. Dynamics of transportation of the Tajik Railway (TSR) is shown, which displays that most of its sections are classified as low-intensity ones. The paper proposes methodical principles, setting and qualitative analysis of the task of rationalization of operational work and organization of car flows for international transportation, taking into account the specifics of the Tajik Railway. There is a problem of complex maintenance of the efficiency of operational work in modern conditions based on the synthesis of the tasks of self-management (rational internal operational technology of the Tajik Railway) and coordination tasks (technological interaction with railway administrations of other states). Author substantiated the necessity of solving this problem. Proposed classification of technological restrictions and controlled variables in the performance of transport takes into account methods for changing external conditions for the functioning of the railway landfill and methods for increasing internal efficiency of its operation. The search for the solution of the problem involves direct search of variants along its ordered set with clipping of groups of variants that do not correspond to constraints, with the subsequent finding of compromise control over a set of effective alternatives.

The Impact

Abstract The main objective of the current study was to assess the impact of the water taken from the ‘Tunisian Refining Industries Company’ on meiobenthic nematodes, before and after a series of treatments in decantation basins followed by its discharge in Bizerte bay, Tunisia. The comparison of environmental parameters of the two types of water was clearly indicative of an improvement in the quality of treated waters after a significant reduction in their loads in hydrocarbons. Overall, the water retained a good quality after being treated by ‘Tunisian Refining Industries Company’ before discharge in the sea. At the end of the experiment, differential responses were observed according to the richness of sediment in organic matter and hydrocarbons. Thus, it was apparent that the nematode assemblage exposed to the treated waters was closer to controls and associated to higher values of abundance, than that under untreated ones. It was also assumed that the species Microlaimus honestus De Man, 1922, Paramonohystera proteus Wieser, 1956 and Cyartonema germanicum Juario, 1972 are sensitive bioindicators of bad environmental statues and of hydrocarbon presence in the environment. On the other hand, Metoncholaimus pristiurus (Zur Strassen, 1894) Filipjev, 1918 would rather be classified as a positive bioindicative species of this type of pollutants.
