An empirical model for estimating roundabout entry capacity for conditions in Jordan has been developed. The performance of the model was compared with the performance of capacity models in Europe. Data, collected from different cities in Jordan, consisted of 775 min of at-capacity operation and included both roundabout traffic and geometric variables. The analysis indicated that circulating traffic flow, widths of entry and circulating roadway, central island diameter, and distance between an entry and a near-side exit had a significant influence on entry capacity. Compared with German, Danish, and French roundabout models, the Jordanian capacity model provided comparable estimates, especially with low levels of circulating traffic.
