Both for every individual and for society at large, transport today is of utmost importance. Our dependence upon transport is best seen when transport is obstructed for reasons such as extreme weather conditions. Transport nowadays relies mostly on road transport. Largely on account of it, negative effects like pollution, noise, accidents, congestion and climate change are increasingly becoming more pronounced. To limit these negative effects, it is necessary to enforce the sustainable mobility paradigm. Its basic goal is to find alternatives to today's predominant motoring. These alternatives are to be based on public transport, alternative fuel vehicles, walking, biking and combinations between them. In its preliminary chapters, this thesis presents reasons behind the necessity of change in the transport sector, continuing then to outlining the basic idea behind the sustainable mobility concept. Presentation of the Dutch model for combining bikes and trains is what follows, serving as a reference for the analysis of existing conditions in two Slovenian cities. It is these two chapters that present the core of my exploration. At the end of this thesis a proposal is presented of measures to improve possibilities for combining bikes and trains in Slovenia that are based on experiences taken from the Dutch model.
