Geographical location of Lithuania determines its role as a transit country. This fact obliges to assure an efficient movement of the goods through the territory of Lithuania. One of the directions to evolve transport sector can be the development of combined road-rail transport (CT). The purpose of the dissertation – on the basis of analysis of scientific works and best practical experience in the field of CT to determine means that stipulate development of CT, arrange them according to the particularity of Lithuanian transport sector, and create a model for the development of combined carriages through the territory of Lithuania. In order to reach this purpose, following tasks are accomplished: 1.Determined all combined road-rail transport elements and their importance; 2.Investigated current market of CT in the EU and technological measures that assure development of these carriages; 3.Carried out an investigation of capabilities of Lithuanian transport system stressing an interaction of road and rail transport; 4.Created model which involves linkage of infrastructure of different transport modes in to one network and assures an optimal exploitation of infrastructure by flows of different transport modes. 5.Explained technological factors that influence possibilities to develop combined carriages through the territory of Lithuania.

Modern railway is a sophisticated system depending on consistency between all its elements. It is not only a self-explanatory component of nowadays-social wealth, however it is also one of environment polluters. What is an actual impact of the railways on the environment of our country, what are the problems and how they are solved? The present master’s study reviews the main law acts, regulating a management of environmental protection of AB “Lietuvos geležinkeliai” (Limited Liability Company “Lithuanian Railways”), a situation of the management of environmental protection, the main problems and perspectives. The objective of the present study is to consider and assess the impact of AB “Lietuvos geležinkeliai” on the environment, to analyse the management of environmental protection in the enterprise, to forecast the means to decrease negative impact or to avoid it, as well as to assess the reasons, impedimental to efficient activities of this process. In order to ensure efficiently observation of the environmental protection, rational use of natural resources, an efficient management apparatus, conditioning efficient observation of the environmental protection, as well as sufficient financing are necessary. Therefore, the analysis of the impact of economical-industrial activities on the environment was selected as the main focus of the present study. The master’s study is comprised of 3 parts. In the first one, there are described legal acts of the Republic of... [to full text]

Disertacijoje nagrinėjama gyvenamųjų teritorijų susisiekimo sistema darnos požiūriu. Pagal sukurtą susisiekimo sistemos analizei naudojamą rodiklių sis-temą, disertacijoje nagrinėjami sprendimų paramos sistemos metodai, tinkantys gyvenamųjų teritorijų susisiekimo sistemos analizes uždaviniams spręsti, tai pat analizuojamos šių metodų integracijos galimybės su geografinėmis informa-cinėmis sistemomis (GIS). Pagrindinis darbo tikslas – sudaryti teorinį modelį, kuris leistų daugiatiksliais sprendimų priėmimo metodais bei GIS technologi-jomis įvertinti gyvenamųjų teritorijų susisiekimo sistemos darną ir darniai planuoti gyvenamųjų teritorijų susisiekimo sistemos vystymąsi ateityje. Dis-ertacijoje siūlomas modelis suteikia galimybę atlikti skirtingų gyvenamųjų teri-torijų susisiekimo sistemų rangavimą, analizuoti įvairias gyvenamųjų teritorijų susisiekimo sistemos vystimosi alternatyvas, jas palyginti bei atrinkti geriausią. Modelis yra integruotas su GIS ir suteikia galimybė atlikti gyvenamųjų teritorijų plėtros tendencijų modeliavimą. / The main goal of the current PhD thesis is urban transport system analysis according sustainability. In dissertation have been analyzed urban areas transport system using integrated decision support system methods with GIS. These methods have been adopted for urban transport system analysis, urban territories ranking according transport system level. Also the indicators system for urban transport system analysis was filled with other important indicators groups for urban sustainability (environmental, socio economic). The aim of the paper cov-ers creation of theoretical model, which could evaluate urban transport system sustainability and perform rational planning of urban future development ac-cording decision support methods and GIS technologies. Also this model could allow executing urban transport system ranking by engineering infrastructure, socio economic and environment aspects. Model could perform comparing of urban development scenarios and to indicate the best one, which satisfies trans-port systems indicators.
