ARCADY (Assessment of Roundabout Capacity and Delay) has been developed over the last 30 years by TRL and is used for predicting capacities, queues, delays (both queueing and geometric) and accident risk at roundabouts.  ARCADY is an easy-to-use and helpful tool to aid the busy traffic engineer in designing new roundabouts as well as assessing the effects of modifying existing designs.
