Using the microscopic computer model NETSIM (NETwork SIMulation), a proposed roundabout at the intersection between Fifth Street and Edmonds Drive in Carson City, Nevada was analyzed in comparison with a four-way stop and a signal controlled intersection. It was found that the roundabout had the lowest average time delays and fuel consumption of the intersection for each type of control modeled, being consistent with field observations. The study provided the qualitative steps to take in simulating the operation of roundabouts and helped NDOT in determining if the location was suitable for a roundabout. It was concluded that the NETSIM model can be used to simulate roundabout operations with an acceptable degree of accuracy, and be useful when making a presentation to administrators or the general public.
