This study deals with the 3-legged roundabout. The objective of this study is to analyze the effectiveness of 3-legged roundabout using aaSIDRA. In pursuing the above, this study gives particular attention to comparative analysis among the roundabout, signalized and non-signalized intersections. The main results are the followings. First, in the case of single-lane approach, the effectiveness of signalized intersections with total entering volume more than 1,500pcph and non-signalized intersections with total entering volume more than 900pcph are analyzed to be rapidly decreasing. Thus, the effectiveness of roundabout is evaluated to be better than those of signalized and non-signalized intersections. Second, in the case of double-lane approach, the effectiveness of roundabout with total entering volume less than 3,000pcph are analyzed to be good. However, in the case of more than 3,000pcph, the signalized intersections are evaluated to be better than the roundabouts.
