The 1999 base year traffic <br />volumes were increased by 3.0 percent per year for six years to reflect the 2005 <br />anticipated background traffic volumes. <br />To obtain total 2005 build -out traffic volumes the development traffic was added <br />to the existing and background traffic volumes. The AM and PM peak -hour <br />turning movements for the studied intersections were then calculated and <br />analyzed for the 2005 build -out year. Figures 2 and 3 show the projected AM <br />and PM peak -hour traffic volumes respectively with the proposed site for the <br />year 2005. <br />Roadway Improvements <br />The following roadway improvements were identified to bring the roadway <br />network up to an acceptable Level -of- Service. <br />• Old NC 86 will need to be widened to a four -lane section with turn lanes <br />from I -40 to I -85. This improvement is consistent with the current <br />thoroughfare plan. <br />• The interchange of I -40 and Old NC 86 will require ramp widening, <br />signalization and turn lane additions. <br />• The interchange of I -85 and Old NC 86 will also require ramp widening, <br />signalization and turn lane additions. <br />Figure 4 shows the roadway improvements that will be needed to accommodate <br />the year 2005 total traffic volumes while Table 3 summarizes the Level -of- <br />Service at each of the studied intersections. <br />
