Abstract
Roundabouts are an increasingly popular alternative to traffic signals for intersection control in the United States. Roundabouts have a number of advantages over traffic signals dependi ng on the conditions. They reduce the severity of c rashes since head-on and rightangle conflicts are nearly eliminated. They reduce through traffic speeds to provide a “calmer” roadwa y environment. They may consume less land area since turn pocket lanes are not needed and also have lower energy and maintenan ce costs. This study evaluated performance of Santasi roundab out in Kumasi, Ghana using micro simulation model. Traffic and geometric data were collected on the field. The analysis revealed that Santasi roundabout was operating at a level of service F, which represented worst conditions. Signalized intersection with 4 ap proach lanes was proposed to control all the moveme nts. Exclusive pedestrian phases were proposed to protect pedestrians .
