INTERSECTION ANALYSIS <br />To complete the intersection analysis, the traffic volumes derived from the development pods were <br />applied to the study intersections shown in figure 11. Travel demand was projected from 2014‐2025 by <br />the trend line analysis method. <br />This method projects Annual Average Daily Traffic (AADT) based on historical trends. Traffic volumes <br />over the past 15 years in this area has increased at 3% annually accordingly. Traffic in the study <br />intersections were increased to the year 2025 by that rate. <br />Both the 2014 and 2025 traffic volumes at the intersections are shown in the following figures. Cross <br />sections for the 5 intersections were determined based on the estimated traffic from the capacity <br />analysis, and coordination with NCDOT. The Level of Service (LOS) was calculated for each new and <br />existing intersection using Synchro. LOS is based on a measure of the average time delay at an <br />intersection and ranges from A to F, with A having the shortest delay time and F having the longest. <br />According to NCDOT Level of Service Definitions the six levels of service are defined as: <br />LOS A: Describes primarily free flow conditions <br />LOS B: Represents reasonably free flow conditions <br />LOS C: Provides for stable operations, but flows approach the range in which small increases will cause <br />substantial deterioration in service <br />LOS D: Borders on unstable flow <br />LOS E: Describes operation at capacity <br />LOS F: Describes forced or breakdown flow <br />The five intersections studied by Volkert were: <br />1)New Road A at Ben Wilson Road <br />2)New Road A at West Ten Road <br />3)West Ten Road at Buckhorn Road <br />4)New Road H at Mt. Willing Road <br />5)US‐70/I‐85 Connector <br /> 86
