The circulation of entry vehicles and circulating vehicles in confluence made the conflict point. Avoidance the conflict is the need to increase road performance. The roundabout of the road is one of the utilities to increase the performances of traffic and reduce congestion. The prevention step is to maximize the utilities to control and manage the traffic. The roundabout dispersed and controlled the traffic flow. According to Makassar roundabout observation, the queuing and delay of vehicles recently occurs. This study aims to an analysis of the roundabout using the microsimulation Vissim program. The model uses the geometric condition of the road and volume of the vehicle that produce the models based on real condition and validation. This model performed the visual condition and calculated the capacity and shows the emission of the operational vehicle, and the general performances are summarized for operation performances at roundabout confluence sections. The result indicated that the roundabout is still useful to reduce the potential of queuing and delay the time of vehicles, and it needs supervision periodically for preventing the traffic from the potential congestion, especially in developing countries. The research result is useful as a reference for improving the capacity of roundabouts. ## Keywords - Roundabout - VisSim - Microsimulation - Transport engineering - Queueing theory - Traffic congestion - Traffic flow (computer networking) - Geometric design - Level of service - Computer science - Engineering - Computer network --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
