Evaluation of roundabout performance in Sharjah
The City of Sharjah is one of the major cities in the confederacy of the UAE. The city highways tend to be of a high standard with at least dual carriageways linking various parts of the city as well as other emirates. Being influenced by the British presence, its roadway network was constructed with roundabouts that serve as the main traffic control devices at most junctions. There are approximately 50 roundabout junctions in the city of Sharjah. Most of these roundabouts have the same shape (circular) and serve four approaches. However, there are some junctions that have oval and other shapes with more than 4 approaches. Geometric and traffic data were collected for several different junctions. Traffic flow parameters were collected for the arrival demand, discharge flow, circulating flow, and the exiting traffic flow for each approach. This paper is intended to demonstrate the operational behaviour of conflicting traffic streams at roundabout. The relationship between the approaching, entering, circulating and exiting traffic volumes for a particular roundabout are demonstrated in order to better understand the operational performance of a roundabout.
