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.
