Unconventional designs for interrupted facilities are considered as popular alternatives to mitigate poor operational performance on arterial roads. With limited resources and increasing demand for cost-effective solutions, unconventional intersection designs have become an integral part of the widely used mitigation measures. In order to evaluate the potential effects on the urban arterial corridor, a simulation-based study on evaluating the operational performance of alternate designs was conducted. The study corridor comprised 15 intersections along the NC-49 corridor (from I-485 to I-85). The alternate designs used in this study align with the proposed plans in the State Transportation Improvement Program (STIP).
