This thesis deals with the public financing of the road transport issue, particularly in the Czech Republic. The quantitative analysis of the revenues from the road transport and capital and maintenance costs on road transport in the Czech Republic in 2001 - 2007 is the fundamental part of this thesis. The vehicle excise tax, fuel tax, road tolls, parking policy revenues and other specific charges belong to the public revenues from the road transport. The output of the thesis is the assessment whether the public revenues from the road transport at least cover the capital and maintenance costs on the road infrastructure and the road transport is therefore a source of the revenues to public sources, or whether, on the contrary, the road transport represents the drain for the public sources and thus also for the tax payers. The evaluation of this situation while including the externalities of road transport is also part of this thesis.
