Interchanges design with analyses of selected interchanges at Rijeka ring

Raskrižja povezuju dviju ili više prometnica te smatraju se najosjetljivijim područjima u prometnoj mreži zbog smanjene sigurnosti i kapaciteta prometa. Za izradu novih ili rekonstrukciju starih raskrižja projektanti moraju zadovoljiti sve propisane uvijete i zakone o gradnji cesta. Rad se bavi podjelom i opisom osnovnih tipova raskrižja. Analiziraju se elementi i projektiranje raskrižja izvan razine. Opisuje se Riječka obilaznica s analizom čvorova Draga i Sv. Kuzam i proračunom potrebne duljine rampa za uključivanje i isključivanje.Intersections connect two or more roads and are considered the most sensitive areas in the transport network due to reduced safety and traffic capacity. For the construction of new or reconstruction of old intersections, designers must fulfill all the prescribed conditions and laws on road construction. The final paper deals with the division and description of the basic types of intersections. Elements and design of off-level intersections are analyzed. The Rijeka bypass is described with an analysis of the intersections Draga and Sv. Kuzam and the calculation of the required length of the ramp for on and off
