Danes je problematika varovanja okolja čedalje pomembnejša, zato se moramo zavedati, da smo prav ljudje glavni krivci za onesnaževanje okolja. Eden izmed glavnih onesnaževalcev je prometni sektor, ki se nenehno povečuje. Zlasti je skrb zbujajoča vztrajna rast cestnega osebnega in tovornega prometa v mestih. Diplomsko delo je sestavljeno iz treh delov, ki se med sabo povezujejo in dopolnjujejo. V uvodu opredelimo problem, za katerega v celotnem diplomskem delu iščemo ustrezne, to je, dovolj celovite rešitve. Sledi prvo poglavje, in sicer teoretična izhodišča, kjer najprej predstavimo prometno politiko Evropske unije, nato preidemo na prometno politiko Republike Slovenije in na koncu predstavimo še prometno politiko Mestne Občine Ljubljana. V drugem delu predstavimo obstoječe stanje v Mestni občini Ljubljana ter zglede dobrih praks v tujini, potem pa te primerjamo s stanjem v Mestni občini Ljubljana. V zadnjem delu podamo na podlagi pomanjkljivosti, ki smo jih zaznali v prejšnjem poglavju, nabor rešitev za izboljšanje prometa v Mestni občini Ljubljana. Nowadays, the issue of environmental protection is becoming increasingly important, so it is imperative we realize that it is us, humans, who are the main cause of environmental pollution. One of the major polluters of the environment is the transport sector which continues to grow steadily. Of particular concern is the continued growth of road passenger and freight transport in urban areas. This thesis is divided into three parts, which are, in turn, interlinked and complementary. In the introduction we define the problem for which we seek solutions throughout the rest of the thesis. These solutions must be relevant to the issue, that is, they must be sufficiently comprehensive. Following are the theoretical starting points in the first chapter, where we introduce the European Union's transport policy, then move on to the transport policy of the Republic of Slovenia, and finally present the transport policy of the Municipality of Ljubljana. In the second part of the thesis we present the current situation in the Municipality of Ljubljana and examples of good practice abroad, which we then go on to compare with the state of affairs in the Municipality of Ljubljana. In the last part we propose a set of solutions to improve freight traffic in the City of Ljubljana, based upon the analysis of deficiencies that were detected in the previous section of the thesis.
