Dyer August 26, 1999 Page 2 Thoroughfare Pign The 1997 Transportation Flan for the Town of Hillsborough indicates the zteed for NC $6 and Old NC $6 to be widened to multi-lane facilities within the project vicinity. Trip Generation Based on the methodology of the ITE Trip Generation Manual {6th i;dition), the proposed development is expected to generate approximately 35,36? trips per average weekday. The breakdown of entering and exiting traffic at peak hours is listed below. PEAK HOUR ENTER E.X,j1T .~~ , A.M 1,450 835 PM 1,SZ0 2.008 ObservationslReeommendatio~as Given the rnafznitude of this development anal its proximity to I-40 and l-$5, we recommend a complete Traffic Impact Analysis (TIA) be performed which identifies current land use proposals within the site, and addresses the capacity of the I-40 I Old NC 86 interchange as it stands to be affected by the proposed development. Given the limited information available addressing land use, the location of the proposed driveway caztnections, and the lane geometry of these connections, it should be noted that the following traffic related eonnxnents are preliminary. Old NC 86 Access. Southern Drive Given, the high traffic volumes expected on Old NC 86 and the function of Old NC $6 as a major north-south connector between I-40 and the Town of Hillsborough, it appears a multi- lane divided t ~~ _ _ ype.facility is appropriate for Old NC 86 in the vicinity of the project. In order to provide ~fuIl moveizaent access onto Oid NC 86 it will be necessary to eompIy with the current t1~Iedian Crossover Guidelines {June, 1998}, should a divided type facility be implemented. With a 55 mile per hoax speed limit postine, a minimum of 1,500 feet is required between median openings; with a 45 mile per hour speed limit pasting, a minimum of 1,000 feet is required between median openings. This criterion should be considered when determining the final location of the proposed driveway connection onto OId NC 8b. • We recommend the existing service road Located approximately 1,400 feet north of the I-~0 / Old NC 86 interchange and the proposed driveway be aligned. • Given the high traffic volumes associated with the site and its southernmost access connection, a multilane facility should be constructed {as a rzainimum) betweexx the southern I-40 !Old NC 86 ramp terminal and the main development entrance. OId NC 86 Access, Northern Drive • We concur with the proposed location of the driveway Located opposite Lafayette Drive. • We recommend providing a northbound right-turn lane on Old NC 86 to renaot-e turning vehicles from the through ctzavement. • We concur with the proposed Southbound left-turn lane on Old NC 86.
