An increased need for transport network leads to additional transport investments which are considered to be an important factor in the area of economic growth regardless their size, layout and efficiency. Transport infrastructure investments may have beneficial influence on the development, such as booming economic growth, improved quality of life, easy access as well as adverse effects on the environment. Large -scale investments in the transport infrastructure result in a more comprehensive assessment, crucial in the area of transport planning and its policy. The basic tool for assessing the economic benefits of infrastructure investments is the cost-benefit analysis, which is indispensable in the projects and programs that are financially supported by the European Union.
In the last decade environmental policy has been considered to play a significant role in the transport policy, which is essential due to positive and negative effects of transport infrastructure investments on the local and global environment. Therefore, integrating environmental effects of investments in cost-benefit analysis is of paramount importance. We are aware that economic implementation strategies and environmental infrastructure interventions are besides direct costs of basic investments significantly affected by the costs and benefits of layout strategies. For that reason the subject matter of the thesis has been the methodology of cost-benefit analysis arising from the environmental effects of the investment, upgraded and modified according to the specific case of transport investments. Such an approach enables proper economic cost- benefit analysis of the environmental investment elements, generated by environmental interventions, which is of utmost importance and has long-term environmental benefits.
