In the existing state of Umut Hospital, the vehicles could barely pass the intersection point, waiting time and tailback length was very high due to signalization times. The entire traffic volume was transferred to the same roundabout junction and this caused a traffic congestion at the heart of intersection point. In the context of our project, intersection types have changed and traffic volume was decreased. The total time which is passed in the intersection point decreased by re planning the signalization-phase diagrams.
