The modern approach to sustainableurban road planning combines traffic demands of the present and future challenges. It is based on the principle that the streets are public space for people, as well as the artery of traffic and transportation. In the urban context, it is necessary to design the street to meet the needs of people for walking, cycling, driving cars and public transport so that none of the modalities is not impeded. This thesis takes into account modern guidelines for planning of urban roads fo all modalities on the 3D model on Slovenska Street between Šubičeva Street and Gosposvetska Street in Ljubljana.
