| Sažetak: | Problem zagađenja zraka usljed saobraćaja je naročito prisutan u urbanim sredinama. Sa porastom saobraćajnog opterećenja, povećava se i emisija štetnih gasova. Ovaj rad proučava kako odabir kružnog toka umjesto klasične semaforizirane raskrsnice može uticati na zagađenje zraka. Analizirane su raskrsnice na dvije lokacije u Sarajevu. Lokacija prve raskrsnice je na presjeku ulica ‘’Hamdije Čemerlića – Put života’’. Lokacija druge raskrsnice je na presjeku ulica ‘’Patriotske lige – Bolnička’’. Sve raskrsnice su modelirane u softverskom paketu PTV Vissim. Izvršena je uporedna analiza za semaforiziranu raskrsnicu i kružni tok na istoj lokaciji u pogledu uticaja na životnu sredinu i osnovnih faktora emisije. Dobijeni su različiti rezultati na obje lokacije. Na prvoj lokaciji se kružni tok pokazao kao bolje rješenje, dok je na drugoj lokaciji klasična semaforizirana raskrsnica bolje rješenje sa aspekta zagađenja životne sredine. Rezultati također pokazuju da propusna moć raskrsnice znatno utiče na emisiju štetnih gasova. |

| ANALYSIS OF THE IMPACT OF THE ROAD INTERSECTION TYPE ON ENVIRONMENTAL IMPACTS AND EMISSIONS | |
| Summary: | The air pollution problem due to traffic is mainly present in urban areas. With the increase in traffic load, the pollution emissions are increased. This work analyzes how a transformation of classic traffic intersections in the roundabout can affect air pollution. Two intersections in Sarajevo were analyzed. The location of the first intersection is at the cross-section of streets “Hamdija Čemerlić” and “Put života”. The location of the second intersection is at the cross-section of the streets “Patriotske lige” and “Bolničke”. All intersections are modeled in the PTV Vissim software package. A comprehensive analysis of a classic traffic intersection and a roundabout in the same location regarding the influence on the environmental impacts and pollution emissions was carried out. Different results were obtained at both locations. In the first location, the roundabout proved to be a better solution, while in the second location, a classic traffic intersection is a better solution from the aspect of pollution. The results also show that the intersection's capacity significantly affects the emission of harmful gases. |
