Abstract:

This report summarizes the findings of a research project aimed at assessing the accuracy of both analytical and microsimulation tools in describing the operational performance of a variety of intersection and interchange types under North Carolina conditions. The three tools evaluated in this study were SYNCHRO10, SIDRA9 and Trans Modeler5. In addition, some basic comparisons with the FHWA CAP-X sketch planning tool was carried out for some sites. The original, Pre-Covid scope of work was to cover ten congested interrupted flow facilities in the field. The revised scope reduced the field effort to six sites, including an isolated and coordinated signalized intersection; a single lane roundabout; a traditional diamond interchange; an offset intersection and a continuous flow intersection with an additional two alternative intersection (AI) sites (Diverging Diamond Interchange and a Reduced Conflict Intersection) processed via a sensitivity analysis to variations in demand volumes, capacity and control conditions.
