This paper introduces a decision problem to evaluate when a single-lane roundabout incorporates a slip lane. Considers six origin-destination (O-D) traffic matrices that represent experimental of different unbalanced flow scenarios (traffic flow into and out of different roundabout approach is different) for a range of volume levels (low, moderate, and high). Performance of single-lane roundabouts with a slip lane is evaluated, based on the calculated roundabout average delay and the 95% queues results, using SIDRA under two control scenarios: yield and free-flow and results are compared to a roundabout with no slip lane. Slip lane right-turning traffic volumes range from 50 to 500 vehicles per hour. Results indicate that a free-flow slip lane exit type provides significant reductions in total roundabout average delay and the 95% queues and can be presented, and perhaps more efficient way, as the best alternative using a decision tree diagrams.
