Optimization of Roundabout at Jadranska Avenue - Dubrovnik Avenue in the City of Zagreb

Porastom prometa u Gradu Zagrebu kroz posljednjih desetak godina došlo je do značajnog smanjenja razine usluge i sigurnosti prometa na raskrižju s kružnim tokom prometa Jadranska avenija-Avenija Dubrovnik. Raskrižje s kružnim tokom prometa predstavlja najveći prometni problem u Zagrebu. Na tri od četiri privoza stvaraju se dugački repovi čekanja u vršnom satnom opterećenju zbog čega dolazi do nemogućnosti slobodnog kretanja vozila ukoliko nema prometnih redara. Također, to je i mjesto s najvećim brojem prometnih nesreća. Iz svega navedenoga proizlazi potreba za prijedlogom rješenja kojim bi se povećala razina usluge i sigurnost odvijanja prometa, te izrada simulacije za predloženu rekonstrukciju.With the growth of traffic in Zagreb over the last decade, there has been a significant reduction in the level of service and traffic safety in the relevant roundabout. Relevant roundabout is the highest traffic problem in Zagreb, and could be said throughout Croatia. Three of the four approach create large waiting queue in peak hour, which results in reduction of free traffic flow movement if there are no traffic officers. Also, this is the location with the largest number of traffic accidents in the whole city and the country. From all of this, there is a need to propose a solution that would increase the level of service and security of traffic and making a simulation for the proposed reconstruction
