The program uses the operational methodologies in the 2010 Highway Capacity Manual (HCM), along with specific default parameters from North Carolina data, to determine level-of-service (LOS) threshold \u201ccapacities\u201d for freeways, multilane highways, two-lane highways and arterial streets. The program is unique in that it provides a graphical display of the measure of effectiveness (MOE) plotted against AADT for each facility type. Users see best case, default case, and worst case curves, plus a highlighted curve for the LOS selected for the analysis. The focus of this effort was to provide technical support to NCDOT programmers who re-programed NCLOS and analyze NCDOT traffic data for the development of default values and input limitations
