The 2000 HCM provides skeleton coverage of modern roundabouts, but does not define LOS: the measure of effectiveness is the quotient of the volume to the capacity. A modern roundabout in the United States is a roundabout in which traffic inside the circle always has priority. Entering traffic is controlled by a yield sign.

Carrying capacity is also optimal at a width of 3.0 to 3.1 metres (9.8 to 10.2 ft), both for motor traffic and for bicycles. [8] Throughput is maximal at 18 miles per hour (29 km/h); as lane width decreases to 3.0 to 3.1 metres (9.8 to 10.2 ft), traffic speed diminishes, and so does the interval between vehicles. [8] [9]
In transportation engineering, traffic flow is the study of interactions between travellers (including pedestrians, cyclists, drivers, and their vehicles) and infrastructure (including highways, signage, and traffic control devices), with the aim of understanding and developing an optimal transport network with efficient movement of traffic and minimal traffic congestion problems.
