Evaluation of conditions in the traffic flow on the crossroad of the main road M4 and Milutin Milankovic Boulevard in Banja Luka

The design and construction of roundabouts, as a solution that will replace the classic intersection, has great application in our area, because it has proven to be the best traffic solution. The aim of this paper is to determine whether the roundabout will provide better traffic conditions than a traffic light. Baseline data were collected by counting traffic at the intersection in question and then processed in the SIDRA INTERSECTION software program. The program analysis covers the following criteria: service level, time losses, costs and emissions. Reducing speed has increased the safety of all road users, which in addition to the environmental aspect is the most important positive effect. With traffic congestion, traffic intensity and service levels have been raised. The construction of the roundabout would continue the trend of construction of roundabouts in Banja Luka, which, in addition to traffic amenities, gives this city an aesthetically pleasing new dimension.
