The increasing human need for transportation further increase the number of vehicle use in the community. The number of such vehicles makes the performance of a road network even harder because the decline in the performance of the road network. Traffic management is needed to resolve the issue, because good planning can improve the performance and reduce accidents. Besides the number of vehicle, a decline in the performance of the road network is also influenced by the behaviour of drivers and the drivers‟ ability to drive vehicles. This study was to evaluate a roundabout in Cianjur using simulation of AIMSUN to know the expected performance. The primary data collection was carried out in the field in the form of traffic flow, queue length and travel time. Secondary data of the roundabout map were obtained from the relevant agencies and used as the basic model. After the basic model was completed, the verification or error checking to see visually the model was performed. Calibration and validation were the next step to make the model as closely as posible to the existing condition. The last was to give the alternative improvements to increase the performance of the roundabout. In the first alternative improvement, the result was not significant or outside the range of 2.10 with the level confidence 95%. This shows that the first alternative is not effective by changing the movement of the vehicle in the roundabout. As for the second alternative improvement, better result was obtained because the parameters of the queue length and travel time were in the range of 2.10 to the same level of confidence 95%. It indicates that the redesign of the roundabout is better and produces significant result.
