The calculation of level of service (capacity of the roundabout) is based on an accelerated virtualization circulation process in a roundabout or roundabout.

Iran vehicles moving at the right speed. Comply with traffic rules and act as regular drivers, ie adequately know the path to follow. Furthermore, heavy vehicles have a slower rate and are slower to react, as would be expected.

Sets the service level values ​​(A to F) as the delay in the gazebo. As service level criteria will be used the Capacity Manual TRB 2010 (HCM 2010), The HCM 2010 considers the delay and the amount of time a driver spends in the queue (delay line) and time spent the front of the queue waiting to enter an acceptable roundabout (geometric delay) gap. Service levels are evaluated by rail, and set access roundabout.

Supports of 3-8 branches, and can be input or output, or input and output.
