摘要：	The U.S. is facing a national crisis as increased traffic and the ensuing congestion and delays it brings adversely affect commerce and quality of life in general. This article describes an informal study of 4 case problems and several simulation scenarios examining geometric design and control delay. The study findings suggest that roundabouts may be a viable option for some stop- or signal-controlled diamond interchanges with low to moderate volumes. Based on the modeling scenarios, roundabout interchanges provide noticeable reductions in control delays, which directly affect the amount of time that drivers sit in traffic. The modern roundabout also uses a narrower bridge, therefore contributing to savings in construction costs.
